This definitely makes it seem that the vent is partially blocked and these explosions are helping "clear the throat" of the volcano (NOTE: this does NOT mean I think something big is going to happen, rather just that it seems to be the reasonable explanation for the bifurcation of the plume). My hunch is that even now, very little "new" juvenile magma has been erupted from Sinabung, but that is pure speculation until there are any analyses of the ash shard morphology or composition.</p> <p>There is also <a href="http://tv1.rtp.pt/noticias/index.php?t=Vulcao-Sinabung-entrou-em-erupcao.rtp&amp;headline=20&amp;visual=9&amp;article=371051&amp;tm=7" target="_blank">some video from Portuguese television</a> Some of the most recent images from the volcano show a strong, single plume with some rock avalanches (possible block and ash flows) on the flanks.<a href="http://www.dailymail.co.uk/news/worldnews/article-1307360/Flights-diverted-21-000-people-evacuated-Indonesian-volcano-continues-erupt-second-day.html" target="_blank"> Evacuations have increased to over 21,000 people</a> living near the volcano and some flights have been diverted due to the taller ash plume. The biggest threat right now is the ash fall from the explosions and as such, the <a href="http://af.reuters.com/article/worldNews/idAFTRE67S07K20100830" target="_blank">government is providing face masks and moving people to sturdier shelter</a>.

What comes next might be a guess for everyone at this point as the Surono, head of the Indonesian Center for Volcanology and Geological Disaster Mitigation admitted again <em>"We don't know what set it off, how long it will continue or whether to expect pyroclastic flows or more powerful eruptions."</em></p> <p><strong><a href="http://scienceblogs.com/eruptions/2010/08/a_busy_day_for_etna_and_galera.php" target="_blank">Etna</a></strong><br /> Not to be forgotten, Etna continues to show signs that it is entering a new cycle of eruptive activity as well (albeit much less of a surprise than Sinabung). Dr. Boris Behncke points us to <a href="http://www.ct.ingv.it/index.php?option=com_content&amp;view=article&amp;id=236%3Aetna-update-29-august-2010&amp;catid=24%3Anews&amp;Itemid=370&amp;lang=en" target="_blank">some new updates from the INGV</a> (<em>italian - top and english - bottom</em>) that describe the explosions and collapses that have been producing the ash fall on Sicily.

Go figure, it's often difficult even to forecast the behavior of a volcano that is extremely well monitored! All depends on the signs that a volcano gives, and how they fit with previous records. At Sinabung there is little of the two, poor instrumental monitoring, and no data for comparison. I hope the volcanologists there will soon have the possibility to install more monitoring equipment - at Pinatubo in 1991, such action helped to save tens of thousands of lives.</p> </div> <drupal-render-placeholder callback="comment.lazy_builders:renderLinks" arguments="0=2210768&amp;1=default&amp;2=en&amp;3=" token="SjvPYkJnuKQwt0ujjnKCBs64Mo9Fk6610UGOsENmC6A"></drupal-render-placeholder> </div> <footer> <em>By <a rel="nofollow" href="http://www.ct.ingv.it" lang="" typeof="schema:Person" property="schema:name" datatype="" content="Boris Behncke, Catania, Italy">Boris Behncke,… (not verified)</a> on 30 Aug 2010 <a href="https://scienceblogs.com/taxonomy/term/27899/feed#comment-2210768">#permalink</a></em> <article typeof="schema:Person" about="/user/0"> <div class="field field--name-user-picture field--type-image field--label-hidden field--item"> <a href="/user/0" hreflang="und"><img src="/files/styles/thumbnail/public/default_images/icon-user.png?itok=yQw_eG_q" width="100" height="100" alt="User Image" typeof="foaf:Image" class="img-responsive" /> </a> </div> </article> </footer> </article> <article data-comment-user-id="148" id="comment-2210769" class="js-comment comment-wrapper clearfix"> <mark class="hidden" data-comment-timestamp="1283152228"></mark> <div class="well"> <strong></strong> <div class="field field--name-comment-body field--type-text-long field--label-hidden field--item"><p>Thanks for correction, Boris.

But did you get my email, or did it get lost in the black hole of the internet known as /dev/null.</p> <p>As for the Sinabung volcano, the few indicators that I get are no good. This eruption appears to be on the phase of dropping and re-starting again with more power. Given the few and little data that I get. But overall this does not look good at the moment. It is also a big factor that the volcano is awakening from a long period of dormancy, and that might not be a good thing.</p> <p>I am assuming (given the data) that new magma is pushing out and re-warming older magma that was left in the magma tubes inside the volcano since the current eruption started. When the new material might reached the surface is a good guess, but I think that is going to happen sooner rather then later.</p> </div> <drupal-render-placeholder callback="comment.lazy_builders:renderLinks" arguments="0=2210773&amp;1=default&amp;2=en&amp;3=" token="FLGIOEn-8DqreFwAhs1g4W-K317rGA3vb9zKrbm5zJc"></drupal-render-placeholder> </div> <footer> <em>By <a rel="nofollow" href="http://earthquakes.jonfr.com" lang="" typeof="schema:Person" property="schema:name" datatype="">Jón FrÃmann (not verified)</a> on 30 Aug 2010 <a href="https://scienceblogs.com/taxonomy/term/27899/feed#comment-2210773">#permalink</a></em> <article typeof="schema:Person" about="/user/0"> <div class="field field--name-user-picture field--type-image field--label-hidden field--item"> <a href="/user/0" hreflang="und"><img src="/files/styles/thumbnail/public/default_images/icon-user.png?itok=yQw_eG_q" width="100" height="100" alt="User Image" typeof="foaf:Image" class="img-responsive" /> </a> </div> </article> </footer> </article> <article data-comment-user-id="0" id="comment-2210774" class="js-comment comment-wrapper clearfix"> <mark class="hidden" data-comment-timestamp="1283160647"></mark> <div class="well"> <strong></strong> <div class="field field--name-comment-body field--type-text-long field--label-hidden field--item"><p>Even if events this far bear an uncanny resemblance to both Tambora and Pinatubo, that's not to say a major eruption is inevitable. </p> <p>Or? ;)</p> </div> <drupal-render-placeholder callback="comment.lazy_builders:renderLinks" arguments="0=2210774&amp;1=default&amp;2=en&amp;3=" token="p7RUCP46LWmxlQZWiT2FBghXNqTFwzTg0zOJuidK4qE"></drupal-render-placeholder> </div> <footer> <em>By <span lang="" typeof="schema:Person" property="schema:name" datatype="">Henrik, Swe (not verified)</span> on 30 Aug 2010 <a href="https://scienceblogs.com/taxonomy/term/27899/feed#comment-2210774">#permalink</a></em> <article typeof="schema:Person" about="/user/0"> <div class="field field--name-user-picture field--type-image field--label-hidden field--item"> <a href="/user/0" hreflang="und"><img src="/files/styles/thumbnail/public/default_images/icon-user.png?itok=yQw_eG_q" width="100" height="100" alt="User Image" typeof="foaf:Image" class="img-responsive" /> </a> </div> </article> </footer> </article> <article data-comment-user-id="0" id="comment-2210775" class="js-comment comment-wrapper clearfix"> <mark class="hidden" data-comment-timestamp="1283164735"></mark> <div class="well"> <strong></strong> <div class="field field--name-comment-body field--type-text-long field--label-hidden field--item"><p>Here is a new news from BBC News.</p> <p><a href="http://www.bbc.co.uk/news/world-asia-pacific-11127918">www.bbc.co.uk/news/world-asia-pacific-11127918</a></p> <p>It is interesting to notice that the eruption is bigger the second time then in the beginning.</p> </div> <drupal-render-placeholder callback="comment.lazy_builders:renderLinks" arguments="0=2210775&amp;1=default&amp;2=en&amp;3=" token="XQGyXWJyFtLEsD2GSvDYdt9d6cZ8yfnEsoouRx4CZv4"></drupal-render-placeholder> </div> <footer> <em>By <a rel="nofollow" href="http://earthquakes.jonfr.com" lang="" typeof="schema:Person" property="schema:name" datatype="">Jón FrÃmann (not verified)</a> on 30 Aug 2010 <a href="https://scienceblogs.com/taxonomy/term/27899/feed#comment-2210775">#permalink</a></em> <article typeof="schema:Person" about="/user/0"> <div class="field field--name-user-picture field--type-image field--label-hidden field--item"> <a href="/user/0" hreflang="und"><img src="/files/styles/thumbnail/public/default_images/icon-user.png?itok=yQw_eG_q" width="100" height="100" alt="User Image" typeof="foaf:Image" class="img-responsive" /> </a> </div> </article> </footer> </article> <article data-comment-user-id="0" id="comment-2210776" class="js-comment comment-wrapper clearfix"> <mark class="hidden" data-comment-timestamp="1283165064"></mark> <div class="well"> <strong></strong> <div class="field field--name-comment-body field--type-text-long field--label-hidden field--item"><p>"Is Sinabung monitoring data publicly available??"

Above that is the stratosphere.</p> <p>In a paper... the one I can't @#$$@# find, there was a discussion about the effects of relative moisture content of tropical air verses higher latitudes on the amount of SO2 that actually made it that high. In a nutshell, the higher humidity tends to leech the SO2 faster from the eruptive column. </p> <p>What this roughly means is that a lower percentage of the SO2 actually makes it to the stratosphere as SO2... already converted H2SO4? Maybe. But tropical systems have to have more punch to reach it. </p> <p>If the system comes up with a Pinatubo level eruption, then I'll start looking for more of those purple sunsets.

Take a look at Friday's pictures and note the large, yellowish area high up on the flank. It's evidence of of solfataric activity from a flank vent (correct Drs K, B, EKoh, Gijs?). Together with the weird, initially horizontal vent visible in the OP, I'd personally stay well away from that side of the volcano.</p> <p>@Raving (#39). A great deal of our human pursuits fall into the "non-neccessity, frivolous waste" category such as the fact that in the '60s, US women spent twice as much on cosmetics as Uncle Sam did on NASA annually. So yes, even if I admit to being a cricket afficionado, I would in the name of intellectual honesty have to include Mohammad Amir and others currently under investigation. What really is an outrage though is that AC Milan just spent over 100 million euros to obtain the services of one of my country men and no one is ever going to convince me that this money couldn't have served humanity far better. Why not a 10% "Football Tax" to fund neccessary public safety projects? ;)</p> <p>@Les Francis (#42)! Hang on! The operant phrase is "quoted as saying". Dr Surono may very well have said that Sinabung was not monitored because it was a Category B volcano and the journalist, either with an axe to grind or wanting to increase his journalistic standing, exchanged "Category B" for "extinct". With some 129(?) active, or Category A, volcanoes to worry about and who knows how many thousand Category B &amp; C volcanoes or volcanic complexes in the country, do you really blame him personally for not watching Sinabung?

All of you who watch the two Etna tremor graphs that are accessible to the public, be aware you're seeing a very partial image of what is going on.</p> <p>Somebody remarked in an earlier thread on the fact that not all data are made public - I had explained this with Civil Defense issues, which as a matter of fact is the truth: since our institute is largely funded by the Italian Civil Defense department, they do have some sort of an intellectual property of these data, although in the end it's us - the scientists of the INGV - who are competent to elaborate and interpret the data.</p> <p>The way how such instrumental data and their interpretation - often a very sensitive affair, since we're talking about the lives and property of millions of people being at stake - should be made public is very much discussed, not only here in Italy. It is a general aim to avoid confusion as much as possible, which is likely to increase with a higher number of interpretations and speculations in circulation, also on blogs as this one, which is under constant observation by the news media waiting for the most sensational and horrible breaking news.</p> <p>Unfortunately there have been events in the past when disagreement between different groups of scientists was directly brought to the news media by the very actors - the volcanologists - with devastating consequences for the credibility of our discipline. The most outstanding example is the Soufrière (Guadeloupe - West Indies) 1976-1977 crisis. In that case two groups of volcanologists had contrasting views on the threat presented by a volcano that had in the past had both cataclysmic, pyroclastic-flow-producing eruptions and small, harmless phreatic explosions. Those views were discussed before the news media from all over the world, causing confusion and disbelief among the affected population (about 73,000 people were evacuated from their homes and business for about 4 months), and eventually the volcano did not erupt catastrophically.</p> <p>It is well possible that the immensely - yet avoidable - disastrous consequences of the relatively small eruption of Nevado del Ruiz (Colombia) on 13 November 1985 were at least in part due to the Soufrière 1976-1977 affair. In order to avoid economic and political pressure, authorities hesitated to carry out evacuations that might turn out unnecessary. The deadly mudflows triggered by the eruption, which killed 23,000 people, travelled several hours after the observed onset of the eruption before they reached populated areas.</p> <p>After the Soufrière crisis and still more so after the Nevado del Ruiz disaster, it has become a philosophy in volcanology to avoid publicly expressing disagreement and speculation that could create confusion. It is preferred to have a single, relatively small team work on a restless volcano during a crisis, and voice their findings via a single outlet to the public. This practice has been applied during a number of recent volcanic crises, most notably Pinatubo (1991) and Soufrière Hills on Montserrat since 1995 (initially different teams working on Montserrat and expressing different views on the risk caused a high degree of consternation in the population and authorities).</p> <p>Maybe this helps a bit to understand why the making public of raw data is viewed by many as inopportune. One may disagree about the usefulness of such limitations, but that's the story behind it.</p> </div> <drupal-render-placeholder callback="comment.lazy_builders:renderLinks" arguments="0=2210840&amp;1=default&amp;2=en&amp;3=" token="fMjYrAi5RL9dk02JXoG5K0QQSq5zqXdg5gDa7nsvQgs"></drupal-render-placeholder> </div> <footer> <em>By <a rel="nofollow" href="http://www.ct.ingv.it" lang="" typeof="schema:Person" property="schema:name" datatype="" content="Boris Behncke, Catania, Italy">Boris Behncke,… (not verified)</a> on 31 Aug 2010 <a href="https://scienceblogs.com/taxonomy/term/27899/feed#comment-2210840">#permalink</a></em> <article typeof="schema:Person" about="/user/0"> <div class="field field--name-user-picture field--type-image field--label-hidden field--item"> <a href="/user/0" hreflang="und"><img src="/files/styles/thumbnail/public/default_images/icon-user.png?itok=yQw_eG_q" width="100" height="100" alt="User Image" typeof="foaf:Image" class="img-responsive" /> </a> </div> </article> </footer> </article> <article data-comment-user-id="0" id="comment-2210841" class="js-comment comment-wrapper clearfix"> <mark class="hidden" data-comment-timestamp="1283229980"></mark> <div class="well"> <strong></strong> <div class="field field--name-comment-body field--type-text-long field--label-hidden field--item"><p>@16 - sorry to go back so far.

I don't know whether making raw seismic data public first will help a lot, though, because it's actually a tremendously complex matter, as I have had the honor to discover when collaborating with experts in volcano seismology in the past two, three years.</p> <p>So what is needed is constant public outreach not only rendering the data available but also explaining them, thus helping to prevent that everybody makes their own little or big story of the data without really understanding them. This is something many of us here in the INGV are strongly advertising - and to some degree really performing - but the current shortening of funding is not helpful when it comes to communicating with the public. Much of what is being done is voluntary. The reduction in funding is certainly not due to a wrong attitude of the scientists here, but of the government. You can see some of the efforts made in recent months by the INGV on YouTube, where scientists are now regularly giving summaries of the seismic activity in Italy: <a href="http://www.youtube.com/user/INGVterremoti">www.youtube.com/user/INGVterremoti</a><br /> Similar contributions are also envisaged for the volcanic activity in Italy.</p> <p>@Raving #80, the military present in the photo gallery you refer to is actually the Alpine Rescue Service, whose staff is making enormous efforts in saving people from distress on the mountain (unfortunately once in vain) every year, every month, every week. These people are all intensely involved in safety issues at Etna, so it is important to understand that their presence at the inauguration of the new control room was fully justified. But surely, a ceremony like this inauguration always has a political touch to it, like it or not, which is part of the work in a public institution. Unfortunately, the response from the political side is currently extremely dissatisfying.</p> <p>@Jón FrÃmann #77, there is currently little evidence that significant quantities of magma are at shallow depth in the feeder system of Etna, it rather looks a pressure buildup similar to that of early September 1979, which culminated with a powerful - and unfortunately deadly - phreatic explosion (which is why access to Etna's summit craters is currently forbidden). Very often during recent decades, when the central conduits of Etna are recharging, long before magma arrives at the surface, there are phreatic or phreatomagmatic explosions. "Long before" means, in most cases, weeks to months. Rarely has there been a totally sudden onset of violent magmatic activity during such a phase of recharge. But time will tell, certainly the incrase in tremor amplitude is adding to the suspense ...</p> </div> <drupal-render-placeholder callback="comment.lazy_builders:renderLinks" arguments="0=2210850&amp;1=default&amp;2=en&amp;3=" token="of8w1ZyrvZSJ9z-BETs_GMUMlfuXBpkPgH5mPh84iVY"></drupal-render-placeholder> </div> <footer> <em>By <a rel="nofollow" href="http://www.ct.ingv.it" lang="" typeof="schema:Person" property="schema:name" datatype="" content="Boris Behncke, Catania, Italy">Boris Behncke,… (not verified)</a> on 31 Aug 2010 <a href="https://scienceblogs.com/taxonomy/term/27899/feed#comment-2210850">#permalink</a></em> <article typeof="schema:Person" about="/user/0"> <div class="field field--name-user-picture field--type-image field--label-hidden field--item"> <a href="/user/0" hreflang="und"><img src="/files/styles/thumbnail/public/default_images/icon-user.png?itok=yQw_eG_q" width="100" height="100" alt="User Image" typeof="foaf:Image" class="img-responsive" /> </a> </div> </article> </footer> </article> <article data-comment-user-id="0" id="comment-2210851" class="js-comment comment-wrapper clearfix"> <mark class="hidden" data-comment-timestamp="1283248693"></mark> <div class="well"> <strong></strong> <div class="field field--name-comment-body field--type-text-long field--label-hidden field--item"><p>Hi, all.

(AP Photo / Roone Patikawa) </p> <p>TEMPO Interactive, a thin white smoke billowing from the top Sinabung in North Sumatra. Height is 20 meters. Five officers of Volcanology and Geological Hazard Mitigation, Geological Agency, Saturday (28 / 8) noted that all the events from the nearest village. </p> <p>16:00 to 19:00 o'clock pm, the peak of the mountain shrouded in fog. The next time till 24.00 pm was not observed any smoke from the active crater. "Mountains do not show any signs of increased activity," the report is the fifth officer. </p> <p>They end up delaying the installation of seismic activity monitoring tool or a seismograph. "We've brought, but the tools have not been installed," said M Hendrasto, head of Volcano Observation and Investigation, Center for Volcanology and Geological Hazard Mitigation. </p> <p>Visual observation of the apparently less sophisticated. Understandably Sunday (29 / 8) at 0:08 pm, there was a roar from the mountain which is located in Tanah Karo. Four minutes later with the eruption of smoke reaching 1500 meters from the lip of the crater. Volcanology who berkantir in Bandung, a direct change Sinabung type of type B into type A and its status is declared "vigilant". </p> <p>These eruptions create panic residents and officials. Why not, because state officials North Sumatra symptoms thick smoke and ash that had emerged since Friday night was common. Even Saturday night carried out counseling to residents that the mountain with an altitude of 2460 meters, is safe. </p> <p>Five officers of Volcanology who came on Saturday just to make observations and coordinate with local governments. Optimism that the mountain will not erupt making them inattentive to install seismographs. New device is installed after the volcanic eruption at a distance of 2.5 kilometers from the summit Sinabung. </p> <p>The result of volcanic and tectonic earthquake recordings from the same appliance can not be monitored from the volcano observation post in Bandung, like other volcanoes. The tape was sent the manual to the Directorate of Volcanology. Yet another volcano type A, can be monitored directly from the central office in Bandung via satellite. </p> <p>"Mount Type B is a volcano that has no character in a magmatic eruption," said Surono, Head of Volcanology. Based on the priority threats, the mountain of type B are not monitored routinely. Sinabung addition, other type B mountain is Mount Merbabu adjacent to the Mount Merapi in Yogyakarta. Then Mount Sibayak in North Sumatra, which is adjacent to Sinabung. </p> <p>Of the 150 volcanoes in Indonesia, the government divided into three types of delam. This classification is based on the standard documentation of the Netherlands since 1600. Type A is a mountain that had erupted after the 1600s the number of 80 units. There are 34 two mountains into type B because the last eruption circa 1600s. The rest is a volcanic type C that there is absolutely no eruptions. </p> <p>Number of volcanoes in Indonesia because the region is the meeting place of three plates of the world. To monitor the volcano spread across the archipelago, the government makes a priority scale. High visibility with full equipment provided to the volcano type A, type B while the volcano is considered sleep. </p> <p>This startling sleeping mountain residents, especially to experts. "The pattern of short eruption, less than 24 hours. It is unusual," said Irwan Meilano, researcher and professor of geodesy Bandung Institute of Technology. He suspects the eruption of the possible results of the process Sinabung plate movement since long. </p> <p>Like when the earthquake in Aceh in 2005, said Irwan, further increasing the activity of a fire in the mountains of Sumatra fault. Sumatra is characterized by the relationship between volcanic activity and the Earth's plates. Almost all the volcanoes are generally lined up on the fault or the fault of Sumatra. "There is a good example of the relationship with the tectonic, volcanic activity," said Irwan who received an honorary doctorate from Japan. </p> <p>According to Irwan, in Indonesia, many of volcano-like Sinabung. Never erupted dozens to hundreds of years ago, but so far as not active. For example Mount Tangkuban and Mount Guntur in Garut. </p> <p>Head of Department of Mines and Energy Government of North Sumatra Province, admitted his side had Utunta Kaban convince displaced residents will Sinabung security. Therefore, he said, in the knowledge during this eruption could be said Sinabung anomaly. "This is the power of God." </p> <p>Irwan explained there is always a period of time long enough to smoke issuing from the mountains and causing earthquakes volcanic eruption. In the case Sinabung eruption, magma probably rose as high as 3-5 kilometers from the magma chamber in the bowels of the earth. </p> <p>Apparently, Irwan said, there is a fairly strong pressure. "There may be changes in tectonic conditions such as an earthquake that changed the pattern of magmatic," he said. But he did not know about type of explosion and strength because there is no historical record of volcanic eruptions, a distance of 90 kilometers from Medan city. </p> <p>To confirm the presence or absence and the potential for the next eruption, scientists need to record the seismic records and information on mountain conditions. So far at least, according to Irwan, molten lava continues to come out to this day can be interpreted as a marker will decrease the eruption. Indeed previous eruptions have been open the volcanic rocks that cover the crater hole. </p> <p>"That's the good news of molten lava," he said. The bad news continues to escape the lava that can freely point to any side of the mountain. It is feared that the lava will go into the river and down to the settlement becomes lava. In addition, there are also potential eruption trigger Sinabung volcanic eruption on nearby. </p> <p>Fortunately Widyanto | ANWAR SISWADI | SOETANA Monang Hasibuan (FIELD) </p> <p>Comments (9) </p> <p>Yes, we do have to believe in what Allah has promised.

What process or processes explain the very largest of eruptions? It would seem that whereas Yellowstone is powered by a hot spot, plate subduction is the answer in the case of Toba, Long Valley and La Garita, and meteor/asteroid strikes for the Siberian and Deccan traps. Should the Midway-to-Hawaii arc, considering its substantial volume, but not the time and thus distance factors, also be regarded as a VLE? It would seem there is a correlation between duration and violence on the one hand, and composition of the magma on the other, same as with "regular" volcanoes. LIPs relate to Kilauea same as very large calderas relate to Chaiten.</p> <p>If you make allowances for the time factor, there are similarities between the the recent Fimvörduhals/Eyjafjallajökull eruptions and the behaviour of the "Yellowstone" hot spot. In the case of the former, first primitive, basaltic, magma erupted, then older, more evolved, magma was remobilised and erupted. The "Yellowstone" hotspot has behaved in what to me appears to be a similar manner.</p> <p>First, "Yellowstone" is a misnomer as it implies a surface-related, fixed geographical location. The surface trace of the hotspot goes back some 17 million years (14-16 million years according to the USGS) through the Snake River Plain to the Columbia Plateau (or Columbia River Basalts). The history of this hotspot ought to be something like this:</p> <p>Some 25 mY ago, the hot spot on its way up through the astenosphere encountered the subducting (Juan de Fuca?) plate, which at that point was adjacent to the North American Plate and still rather solid, resulting in an uplift and accumulation of primitive magma. The uplift caused the plates to fracture and resulted in the Columbia River Basalts, several million years' worth of accumulated primitive magma reaching the surface in the geologic blink of an eye. The subsequent "remobilisation" of the old plate (and, possibly and partially, the overlying NAP) resulted in more evolved magmas, hence the caldera forming so-called "super-eruptions" of the Snake River Plain to Yellowstone. </p> <p>In the future (tens of millions of years) as the material of the subducting plate is assimilated into the astenosphere and (partially) remobilised by the hotspot, there will probably be fewer caldera-forming VLEs. Once the subducting plate is completely gone, the surface expressions of the hot spot might even result in a chain of very large basaltic shield volcanoes.

One esteemed professor smoked it, another ate it raw and the third drank a liquour based concoction of it. The only one (the famous one) who made it to the night-club was tossed out of the night-club after starting to rearrange the dance-floor. He had drunk the amanita muscaria-boose concoction.<br /> A russian guest-lecturer advised us of how they do it nowadays, since you have a tendency to get violently sick before getting the effect (like being hung-over before you get drunk).

In the last days we followed your posts about the Sinabung quite attentively because we are directly concerned with the actual developments. We come from Germany and at the moment we are staying in north Sumatra, because we work in Kabanjahe for two months. At the time of the eruption on sunday morning we stayed in Kabanjahe, but for our own security we where brought to Medan on sunday afternoon, which is about 60km away from mount Sinabung.<br /> Now we are staying in a hotel in Medan and watch the developments very closely. Our plan is maybe to move back to Kabanjahe this weekend, given that there are no more bigger eruptions until then. Kabanjahe is about 10km away from mount sinabung and we would stay there until October 5th.<br /> What do you think? Are the local predictions reliable enough, if they decrease the alert status? Or â if they do not decrease the alert status, what would you suggest to do in that case? Staying in Medan is annoying, too â even if we can do some of our work from here, we are not lucky with the situation, because our actual work is to give seminars to social workers in Kabanjahe.<br /> What about the risk when a new eruption happens? Our feeling is that it is not a good idea to go back â but we actually havenât got a clue about volcanoesâ¦</p> </div> <drupal-render-placeholder callback="comment.lazy_builders:renderLinks" arguments="0=2210872&amp;1=default&amp;2=en&amp;3=" token="Ptu8cjU3w3_SJzgbhNUw3v0Auk_31MqW8GcBn-TAqTk"></drupal-render-placeholder> </div> <footer> <em>By <span lang="" typeof="schema:Person" property="schema:name" datatype="">Nudge and Celly (not verified)</span> on 01 Sep 2010 <a href="https://scienceblogs.com/taxonomy/term/27899/feed#comment-2210872">#permalink</a></em> <article typeof="schema:Person" about="/user/0"> <div class="field field--name-user-picture field--type-image field--label-hidden field--item"> <a href="/user/0" hreflang="und"><img src="/files/styles/thumbnail/public/default_images/icon-user.png?itok=yQw_eG_q" width="100" height="100" alt="User Image" typeof="foaf:Image" class="img-responsive" /> </a> </div> </article> </footer> </article> <article data-comment-user-id="0" id="comment-2210873" class="js-comment comment-wrapper clearfix"> <mark class="hidden" data-comment-timestamp="1283392421"></mark> <div class="well"> <strong></strong> <div class="field field--name-comment-body field--type-text-long field--label-hidden field--item"><p>Hello Nudge and Celly!</p> <p>Our gracious blog-host has moved the entire blog to a new location.

My hunch is that this explosion might be the start of more and the heat from the magma interacted with groundwater near the summit to cause the explosion - a very common precursor activity at a composite cone like Sinabung (think about the events leading to the eruption at <a href="http://scienceblogs.com/eruptions/redoubt/" target="_blank">Redoubt</a>).[<em>speculation</em>] However, Surono, head of the Indonesian Center for Volcanology and Geological Disaster Mitigation, warned that <em>"we have little knowledge in terms on its eruptive patterns and general forms."</em></p> <p><a href="http://scienceblogs.com/eruptions/Sinabung.jpg"><img src="http://scienceblogs.com/eruptions/wp-content/blogs.dir/312/files/2012/04/i-231528a79b6d38a1ce86e72f98be89ac-Sinabung-thumb-400x213-55156.jpg" alt="i-231528a79b6d38a1ce86e72f98be89ac-Sinabung-thumb-400x213-55156.jpg" /></a><br /><em>A closer look at the August 29, 2010 eruption of Sinabung.

I try to be careful about such things as to look for imminent catastrophes, but since we had been discussing earlier about other possible mechanisms involved in intraplate volcanism (which is not the case here), such as crustal thinning due to underlying faults, I thought that, like it has been supposed for Krakatoa (Wikipedia), a thinner underlying crust could also explain the explosive origin of Toba's caldera, and that such thin crust could also be present under the segment of Sumatra Fault from Toba to Kempar, since a similar faulting pattern is present there.<br /> As for Katla and Eyjaf's connection, for what I've been reading, I'm still not 100% convinced there are no connections, but I'm getting there too.<br /> #23 @Motsfo: According to more knowledgeable people at this blog, those quakes are purely tectonic (see earlier threads).</p> </div> <drupal-render-placeholder callback="comment.lazy_builders:renderLinks" arguments="0=2210683&amp;1=default&amp;2=en&amp;3=" token="mJi-xZDuls88dq2Vu-cyTktBfBeTxvImNFsC0nQ6IhE"></drupal-render-placeholder> </div> <footer> <em>By <span lang="" typeof="schema:Person" property="schema:name" datatype="">Renato Rio (not verified)</span> on 29 Aug 2010 <a href="https://scienceblogs.com/taxonomy/term/27899/feed#comment-2210683">#permalink</a></em> <article typeof="schema:Person" about="/user/0"> <div class="field field--name-user-picture field--type-image field--label-hidden field--item"> <a href="/user/0" hreflang="und"><img src="/files/styles/thumbnail/public/default_images/icon-user.png?itok=yQw_eG_q" width="100" height="100" alt="User Image" typeof="foaf:Image" class="img-responsive" /> </a> </div> </article> </footer> </article> <article data-comment-user-id="0" id="comment-2210684" class="js-comment comment-wrapper clearfix"> <mark class="hidden" data-comment-timestamp="1283095433"></mark> <div class="well"> <strong></strong> <div class="field field--name-comment-body field--type-text-long field--label-hidden field--item"><p>#24 Correction: Kembar, Indonesia.<br /><a href="http://www.volcano.si.edu/world/volcano.cfm?vnum=060106=A">http://www.volcano.si.edu/world/volcano.cfm?vnum=060106=A</a></p> </div> <drupal-render-placeholder callback="comment.lazy_builders:renderLinks" arguments="0=2210684&amp;1=default&amp;2=en&amp;3=" token="fAQIQQw_kWnvJrS4ym02P84k2FtA1IzxYjFoJcNvX5s"></drupal-render-placeholder> </div> <footer> <em>By <span lang="" typeof="schema:Person" property="schema:name" datatype="">Renato Rio (not verified)</span> on 29 Aug 2010 <a href="https://scienceblogs.com/taxonomy/term/27899/feed#comment-2210684">#permalink</a></em> <article typeof="schema:Person" about="/user/0"> <div class="field field--name-user-picture field--type-image field--label-hidden field--item"> <a href="/user/0" hreflang="und"><img src="/files/styles/thumbnail/public/default_images/icon-user.png?itok=yQw_eG_q" width="100" height="100" alt="User Image" typeof="foaf:Image" class="img-responsive" /> </a> </div> </article> </footer> </article> <article data-comment-user-id="0" id="comment-2210685" class="js-comment comment-wrapper clearfix"> <mark class="hidden" data-comment-timestamp="1283098668"></mark> <div class="well"> <strong></strong> <div class="field field--name-comment-body field--type-text-long field--label-hidden field--item"><p>@Passerby @Maik:<br /> The more I dig in my quest for understanding the more puzzled I get. I thought the question about the existence of shield volcanoes at subduction zones was solved. But I went on, and here I am again, sharing my doubts with you guys. Feel free to ignore it, but I thought that maybe they could heat up the debates over this thread. (OK. After this post I must say good night and go back to my errands).<br /> Shield volcanoes = volcanic edifice formed either by more fluid, mafic magma, poor in SiO2, or pyroclastic surges (???!!!! - which means "very explosive eruption"), providing a wide angle of magma deposit.<br /> Andesitic magma = felsic, high SiO2 content.<br /> Then I stumbled on this article (<a href="http://www.nature.com/nature/journal/v461/n7268/full/nature08510.html#B1">http://www.nature.com/nature/journal/v461/n7268/full/nature08510.html#B1</a>) - abstract, calling for "A dearth of intermediate melts at subduction zone volcanoes and the petrogenesis of arc andesites"<br /> My question: how come there be "andesitic shield volcanoes" other than formed by SiO2 rich pyroclastic flows of explosive etiology? We are supposed to find conical-shaped "andesitic stratovolcanoes", because of their highly viscous lavas, but not "shield-shaped".<br /> So, I'm kind of back to where I started:<br /> Could Kembar be one of this type of "explosive" andesitic shield volcano, relating it to Toba's explosive genesis?<br /> Thanks for reading this.</p> </div> <drupal-render-placeholder callback="comment.lazy_builders:renderLinks" arguments="0=2210685&amp;1=default&amp;2=en&amp;3=" token="nAygOu0C3elqyETCiaSYn03duXep_CuNY_C_K7RJou8"></drupal-render-placeholder> </div> <footer> <em>By <span lang="" typeof="schema:Person" property="schema:name" datatype="">Renato Rio (not verified)</span> on 29 Aug 2010 <a href="https://scienceblogs.com/taxonomy/term/27899/feed#comment-2210685">#permalink</a></em> <article typeof="schema:Person" about="/user/0"> <div class="field field--name-user-picture field--type-image field--label-hidden field--item"> <a href="/user/0" hreflang="und"><img src="/files/styles/thumbnail/public/default_images/icon-user.png?itok=yQw_eG_q" width="100" height="100" alt="User Image" typeof="foaf:Image" class="img-responsive" /> </a> </div> </article> </footer> </article> <article data-comment-user-id="0" id="comment-2210686" class="js-comment comment-wrapper clearfix"> <mark class="hidden" data-comment-timestamp="1283101944"></mark> <div class="well"> <strong></strong> <div class="field field--name-comment-body field--type-text-long field--label-hidden field--item"><p>RR pointed out: According to Google Earth and SIV, there is a neighbor volcano (15 km to the NE), Sibayak, that emitted an ashcloud in 1881.</p> <p>If you look at the near neighbor, you're struck by the visual similarity of these two stratovolcanoes.</p> <p><a href="http://www.indonesiavolcanoes.com/mount-sibayak-trekking.htm">www.indonesiavolcanoes.com/mount-sibayak-trekking.htm</a></p> <p>I think Erik is correct.

In addition to the subduction zone and the associated Sunda Arc off the west coast of the island, Sumatra also has a large strike-slip fault, the so-called Great Sumatran Fault, running the entire length of the island. </p> <p>This fault zone accommodates most of the strike-slip motion associated with the oblique convergence between the Indo-Australian and Eurasian plates. The fault ends in the north just below the city of Banda Aceh, which was devastated in the 2004 Indian Ocean earthquake. </p> <p>&gt;&gt;&gt;&gt;After the December 2004 earthquake, pressure on the Great Sumatran Fault has increased tremendously, especially in the north.</p> <p>We have the northern end of this island dominated by a constrained and very large and powerful fault, that has increased in activity *markedly* since 2004. The volcanoes of interest lie parallel to this Great Fault.</p> <p>Now we have a jump in magmetic intrusion below a very quiet volcano considered 'safe' until a few days ago, having a more active neighbor with 2 active vents. We have geothermal field that supported the first power plant in Indonesia, one that is slated for expansion shortly.</p> <p>I wouldn't be worried about an eruption. I would be very, very worried about another massive earthquake in the area.</p> <p>Somebody tap on PVMBG's horn and get their attention. They have dozens of able geologists who should be looking for signs of rapidly increasing groundwater pressure, pronto!</p> </div> <drupal-render-placeholder callback="comment.lazy_builders:renderLinks" arguments="0=2210686&amp;1=default&amp;2=en&amp;3=" token="6w0OgNjYm8lkZoQyJZNRciwGQ4hLU3V9vLk3NVI5-C4"></drupal-render-placeholder> </div> <footer> <em>By <span lang="" typeof="schema:Person" property="schema:name" datatype="">Passerby (not verified)</span> on 29 Aug 2010 <a href="https://scienceblogs.com/taxonomy/term/27899/feed#comment-2210686">#permalink</a></em> <article typeof="schema:Person" about="/user/0"> <div class="field field--name-user-picture field--type-image field--label-hidden field--item"> <a href="/user/0" hreflang="und"><img src="/files/styles/thumbnail/public/default_images/icon-user.png?itok=yQw_eG_q" width="100" height="100" alt="User Image" typeof="foaf:Image" class="img-responsive" /> </a> </div> </article> </footer> </article> <article data-comment-user-id="0" id="comment-2210687" class="js-comment comment-wrapper clearfix"> <mark class="hidden" data-comment-timestamp="1283102623"></mark> <div class="well"> <strong></strong> <div class="field field--name-comment-body field--type-text-long field--label-hidden field--item"><p>Couldn't resist a quick lurking and... bingo!<br /> Hope the guys at PVMBG show your lucidity, Passerby.</p> </div> <drupal-render-placeholder callback="comment.lazy_builders:renderLinks" arguments="0=2210687&amp;1=default&amp;2=en&amp;3=" token="gQkojv7ZsNnypus7aylz_jmAtAPQS9RDHkRmK4x8WgQ"></drupal-render-placeholder> </div> <footer> <em>By <span lang="" typeof="schema:Person" property="schema:name" datatype="">Renato Rio (not verified)</span> on 29 Aug 2010 <a href="https://scienceblogs.com/taxonomy/term/27899/feed#comment-2210687">#permalink</a></em> <article typeof="schema:Person" about="/user/0"> <div class="field field--name-user-picture field--type-image field--label-hidden field--item"> <a href="/user/0" hreflang="und"><img src="/files/styles/thumbnail/public/default_images/icon-user.png?itok=yQw_eG_q" width="100" height="100" alt="User Image" typeof="foaf:Image" class="img-responsive" /> </a> </div> </article> </footer> </article> <article data-comment-user-id="0" id="comment-2210688" class="js-comment comment-wrapper clearfix"> <mark class="hidden" data-comment-timestamp="1283103326"></mark> <div class="well"> <strong></strong> <div class="field field--name-comment-body field--type-text-long field--label-hidden field--item"><p>Sorry about the lack of posts....well the volcano bussiness is off season<br /> I've been not only frantically prepping for class and my Eyja talk....any news from Pall Einerson?<br /> or from the volcano front<br /> i dont see nothing coming from icelandic univ's<br /> at least some sismic data</p> </div> <drupal-render-placeholder callback="comment.lazy_builders:renderLinks" arguments="0=2210688&amp;1=default&amp;2=en&amp;3=" token="B63QM_MldWkAG29UxIkvtjiTRTDY0RER7oLxhXCNfvs"></drupal-render-placeholder> </div> <footer> <em>By <a rel="nofollow" href="http://snowmicrophysics.blogspot.com/" lang="" typeof="schema:Person" property="schema:name" datatype="">small bulge (not verified)</a> on 29 Aug 2010 <a href="https://scienceblogs.com/taxonomy/term/27899/feed#comment-2210688">#permalink</a></em> <article typeof="schema:Person" about="/user/0"> <div class="field field--name-user-picture field--type-image field--label-hidden field--item"> <a href="/user/0" hreflang="und"><img src="/files/styles/thumbnail/public/default_images/icon-user.png?itok=yQw_eG_q" width="100" height="100" alt="User Image" typeof="foaf:Image" class="img-responsive" /> </a> </div> </article> </footer> </article> <article data-comment-user-id="0" id="comment-2210689" class="js-comment comment-wrapper clearfix"> <mark class="hidden" data-comment-timestamp="1283107859"></mark> <div class="well"> <strong></strong> <div class="field field--name-comment-body field--type-text-long field--label-hidden field--item"><p>Looks like another eruption, this time to at least 20,000 feet.</p> <p>IDD41300<br /> VA ADVISORY<br /> DTG: 20100830/0038Z<br /> VAAC: Darwin </p> <p>VOLCANO: Sinabung 0601-08<br /> PSN: N0310 E09823<br /> AREA: Sumatra<br /> SUMMIT ELEV: 2460M</p> <p>ADVISORY NR: 2010/3<br /> INFO SOURCE: CVGHM<br /> AVIATION COLOUR CODE: RED<br /> ERUPTION DETAILS: CVGHM REPORTED VA TO FL200 AT 30/2330Z.</p> <p>OBS VA DTG: 30/0030Z<br /> OBS VA CLD:<br /> SFC/FL200 N0315 E09830 - N0305 E09720 - N0205 E09810 -<br /> N0315 E09830 MOV SW 10KT</p> <p>FCST VA CLD +6HR: 30/0630Z<br /> SFC/FL200 N0315 E09830 - N0255 E09655 - N0130 E09725 - N0315 E09830<br /> FCST VA CLD +12HR: 30/1230Z<br /> SFC/FL200 N0315 E09830 - N0240 E09550 - N0100 E09645 - N0315 E09830<br /> FCST VA CLD +18HR: 30/1830Z<br /> SFC/FL200 N0315 E09830 - N0205 E09500 - S0020 E09625 - N0315 E09830 </p> <p>RMK: VA NOT IDENTIFIABLE ON SAT IMAGERY DUE TO METEOROLOGICAL<br /> CLOUD.

According to my ideas, and the ideas that I base that on. The Upptyppingar appears to be a volcano in formation. It has not erupted yet as a volcano with a magma chamber. But it is going to do so at one time in history. When that might happen I do not know.</p> <p>If we are extremely lucky we might get one off cone volcanoes there in less then 5 to 10 years. But I am expecting big eruption in 30 to 50 years, based on current models and given the number of earthquakes. But only time is going to tell me what is going to happen, and how this is going to evolve at Upptyppingar.</p> </div> <drupal-render-placeholder callback="comment.lazy_builders:renderLinks" arguments="0=2210691&amp;1=default&amp;2=en&amp;3=" token="TWZEuWIJfB9ZuXstmSoaCBxd35lKOWHc1abIAqYEjBc"></drupal-render-placeholder> </div> <footer> <em>By <a rel="nofollow" href="http://earthquakes.jonfr.com" lang="" typeof="schema:Person" property="schema:name" datatype="">Jón FrÃmann (not verified)</a> on 29 Aug 2010 <a href="https://scienceblogs.com/taxonomy/term/27899/feed#comment-2210691">#permalink</a></em> <article typeof="schema:Person" about="/user/0"> <div class="field field--name-user-picture field--type-image field--label-hidden field--item"> <a href="/user/0" hreflang="und"><img src="/files/styles/thumbnail/public/default_images/icon-user.png?itok=yQw_eG_q" width="100" height="100" alt="User Image" typeof="foaf:Image" class="img-responsive" /> </a> </div> </article> </footer> </article> <article data-comment-user-id="0" id="comment-2210692" class="js-comment comment-wrapper clearfix"> <mark class="hidden" data-comment-timestamp="1283109816"></mark> <div class="well"> <strong></strong> <div class="field field--name-comment-body field--type-text-long field--label-hidden field--item"><p>According to an article in the German news magazine 'Der Spiegel' locals reported seeing lava flowing from the Sinabung volcano:</p> <p><a href="http://www.spiegel.de/wissenschaft/natur/0,1518,714420,00.html">http://www.spiegel.de/wissenschaft/natur/0,1518,714420,00.html</a></p> <p>The google translation reads as follows:</p> <p>"Local media reported, citing witnesses, leaking lava was seen from miles - even in the tourist area of Berastagi to the north of the island.

Fluid, Hawaiian-style lava does not come out of this type of volcano, especially not at the start of a new eruption after long repose. Maybe there is a lava dome pushing from the summit, although I would expect this to happen later on, after the path for the rising magma has been cleared.</p> <p>There are indeed spectacular photos at Daylife, which show that there are several vents at the summit and on the side of the volcano:<br /><a href="http://www.daylife.com/photo/0e6T0SP25Vbfx?q=volcano">www.daylife.com/photo/0e6T0SP25Vbfx?q=volcano</a><br /><a href="http://www.daylife.com/photo/037rcQD2gSdXb?q=volcano">www.daylife.com/photo/037rcQD2gSdXb?q=volcano</a><br /><a href="http://www.daylife.com/photo/04bUeSkcd33Px?q=volcano">www.daylife.com/photo/04bUeSkcd33Px?q=volcano</a></p> <p>Three scenarios can be envisaged:</p> <p>(1) Soufrière de la Guadeloupe (1976-1977) - phreatic explosions and probably magma uprise, without culminating in a magmatic eruption; similar events have occurred at Fourpeaked (Alaska) in 2006, Koaryaksky (Kamchatka) in 2008-2009 and numerous other volcanoes. One particular example is Ontake in Japan, which erupted in 1979 after possibly up to 30,000 years, but all that happened was a few phreatic bursts and then the volcano calmed down again.</p> <p>(2) Unzen (1990-1995) - phreatic explosions followed by lava dome growth without much explosive activity. Much of the disaster caused by the Unzen eruption was due to collapse of the lava dome, which grew on a very steep, unstable flank and thus often crumbled, generating pyroclastic flows. A variation on the theme is Soufrière Hills (Montserrat) where initial phreatic explosions were also followed by dome growth and frequent dome collapse, but there was also strong explosive (Vulcanian to sub-Plinian) activity.</p> <p>(3) Pinatubo (1991) - initial phreatic explosions followed by dome growth and then a massive cataclysmic, caldera-forming eruption, which in turn was followed by lava dome growth.</p> <p>A Pinatubo-like scenario is possible but less likely than the other two scenarios. If Sinabung behaves like Unzen, i.e. if it builds a lava dome at its summit or on its steep upper flank, there is a high risk of pyroclastic flows generated by dome collapse. Seismic and deformation monitoring is imperative here, to see whether a large volume of magma is making its way to the surface, as at Pinatubo, or whether it is rather modest and will produce a lava dome-building eruption.</p> <p>Out of topic but certainly of interest, a little Etna update:</p> <p>Since the strong 25 August phreatomagmatic explosion at the Bocca Nuova at Etna's summit, there have been numerous smaller and 8 medium-intensity explosions, the latter of which generated conspicuous but short-lived ash emissions. Observations made at close range disclose that these events are virtually noiseless, and the ejected ash is altered, lithic (old, not new hot magmatic) material so far.</p> <p>Access to the summit craters of Etna is now prohibited by decree of the Prefecture of Catania. The situation is considered highly dangerous; during a strong phreatic or phreatomagmatic explosion at the Bocca Nuova on 12 September 1979, nine tourists were killed and more than 20 injured.</p> <p>It is likely that the current explosive sequence is a vent-clearing activity, as magma is reoccupying the conduits of the summit craters. Evidence for magma uprise is also in the fact that fumarole temperatures on the crater rims and on the outer southwest slope of the central summit cone (which hosts the Bocca Nuova and Voragine craters) are rising, leading to increased sulfur deposition (at temperatures above 120° C).</p> <p>Updates are posted in Italian and English at the INGV web site - <a href="http://www.ct.ingv.it">www.ct.ingv.it</a></p> </div> <drupal-render-placeholder callback="comment.lazy_builders:renderLinks" arguments="0=2210717&amp;1=default&amp;2=en&amp;3=" token="pz46RpJSsxG5ffRw4zbXtgXSJ9Ve1aDABOr5hp2hh9M"></drupal-render-placeholder> </div> <footer> <em>By <a rel="nofollow" href="http://www.ct.ingv.it" lang="" typeof="schema:Person" property="schema:name" datatype="" content="Boris Behncke, Catania, Italy">Boris Behncke,… (not verified)</a> on 29 Aug 2010 <a href="https://scienceblogs.com/taxonomy/term/27899/feed#comment-2210717">#permalink</a></em> <article typeof="schema:Person" about="/user/0"> <div class="field field--name-user-picture field--type-image field--label-hidden field--item"> <a href="/user/0" hreflang="und"><img src="/files/styles/thumbnail/public/default_images/icon-user.png?itok=yQw_eG_q" width="100" height="100" alt="User Image" typeof="foaf:Image" class="img-responsive" /> </a> </div> </article> </footer> </article> <article data-comment-user-id="0" id="comment-2210718" class="js-comment comment-wrapper clearfix"> <mark class="hidden" data-comment-timestamp="1283136728"></mark> <div class="well"> <strong></strong> <div class="field field--name-comment-body field--type-text-long field--label-hidden field--item"><p>Thanks so much for that insight Boris, very interesting read!</p> </div> <drupal-render-placeholder callback="comment.lazy_builders:renderLinks" arguments="0=2210718&amp;1=default&amp;2=en&amp;3=" token="NA7Tg1dRXo5ip2tqu0WxYSm6_6CiRxzBNVDUgPGY2JY"></drupal-render-placeholder> </div> <footer> <em>By <a rel="nofollow" href="http://www.typhoonfury.com" lang="" typeof="schema:Person" property="schema:name" datatype="">James Reynolds (not verified)</a> on 29 Aug 2010 <a href="https://scienceblogs.com/taxonomy/term/27899/feed#comment-2210718">#permalink</a></em> <article typeof="schema:Person" about="/user/0"> <div class="field field--name-user-picture field--type-image field--label-hidden field--item"> <a href="/user/0" hreflang="und"><img src="/files/styles/thumbnail/public/default_images/icon-user.png?itok=yQw_eG_q" width="100" height="100" alt="User Image" typeof="foaf:Image" class="img-responsive" /> </a> </div> </article> </footer> </article> <article data-comment-user-id="0" id="comment-2210719" class="js-comment comment-wrapper clearfix"> <mark class="hidden" data-comment-timestamp="1283139468"></mark> <div class="well"> <strong></strong> <div class="field field--name-comment-body field--type-text-long field--label-hidden field--item"><p>A short clip from BBC: <a href="http://www.bbc.co.uk/news/world-asia-pacific-11128800">http://www.bbc.co.uk/news/world-asia-pacific-11128800</a></p> </div> <drupal-render-placeholder callback="comment.lazy_builders:renderLinks" arguments="0=2210719&amp;1=default&amp;2=en&amp;3=" token="v4woZFP_uDL4atO-iayd1Z_QMFWY9qoXndbedFk13oo"></drupal-render-placeholder> </div> <footer> <em>By <span lang="" typeof="schema:Person" property="schema:name" datatype="">Max (not verified)</span> on 29 Aug 2010 <a href="https://scienceblogs.com/taxonomy/term/27899/feed#comment-2210719">#permalink</a></em> <article typeof="schema:Person" about="/user/0"> <div class="field field--name-user-picture field--type-image field--label-hidden field--item"> <a href="/user/0" hreflang="und"><img src="/files/styles/thumbnail/public/default_images/icon-user.png?itok=yQw_eG_q" width="100" height="100" alt="User Image" typeof="foaf:Image" class="img-responsive" /> </a> </div> </article> </footer> </article> <article data-comment-user-id="0" id="comment-2210720" class="js-comment comment-wrapper clearfix"> <mark class="hidden" data-comment-timestamp="1283139929"></mark> <div class="well"> <strong></strong> <div class="field field--name-comment-body field--type-text-long field--label-hidden field--item"><p>@#60 - Heh.

I suppose there might be a chance that bending crust that is 'prefractured' in an opposite orientation to bending axis could provide a route for magma flow to the surface. Just enough to provide hydrothermal heat source and fumaroles, but not vigorous eruptions in the recent past.</p> <p>So one could guess that a build up of stress on the Great Sumatran Fault, perhaps near the segments which haven't been active in several hundred years - note that the old rupture dates roughly correspond to the approximate period of last known large eruption for Sinabung) - are under considerable stress buildup from the 2004 Aceh quake.</p> <p>This is why I fear that a major EQ is much more likely than any large eruption, and why I concur with Erik that we're seeing old material being expelled under a sharp rise in pressure under Sinabung and perhaps under adjacent volcanic centers, given the anecdotal evidence of paired minor ash eruptions in early 1880s (same period as Krakatoa to the south, and mid-island Dempo and Kaba eruptions - all part of the southern domain subduction region of the GSF). </p> <p>This is the provenance of the Cal-Tech group who has been chugging away on the tectonics of North Sumatra for a decade.

This your blog is an outstanding example of generosity in sharing knowledge and arousing curiosity as a mean of improving our understanding of the world and the relationships between man, science and Nature.<br /> And I also want to thank Boris, ECho and all the other collaborators, as well as our fellow bloggers who, with their valuable comments and posts contribute to keep this blog "rocking". It's been a thrilling experience to be around.<br /> I must confess I'm still far from grasping the whole picture in which concerns magma and volcanoes, but I'm fascinated and eager to learn more.<br /> I'm specially interested in understanding the mechanisms governing plate tectonics and hotspots. Although my expertise is yet insufficient to go deep into the matter, I daresay that, concerning the mantle plume theory, there must be some kind of gap between what is being explained and what is really taking place underneath. Except for Hawaii, where mantle plume provides a very plausible explanation for volcanism, there must be a link between sinking of old plates and hotspots elsewhere. We've seen that kind of connection in Iceland and Yellowstone and recent EQ activity in ancient subduction zones appear as good examples of weird behaviors of magma formation.<br /> It has been said recently in this blog that the mantleplume.org would be a questionable source, though the article in Highly Allochthonous points to the site.<br /> Maybe you could give us some opinion about this as well as some other reliable sources in the net (or books) where a layman like me could get a good perspective in the actual course of debate.<br /> Many thanks in advance.</p> </div> <drupal-render-placeholder callback="comment.lazy_builders:renderLinks" arguments="0=2210593&amp;1=default&amp;2=en&amp;3=" token="91l_p6POsbzRphJ5B4qWbUBd32pd2V402VFEy_hq7Os"></drupal-render-placeholder> </div> <footer> <em>By <span lang="" typeof="schema:Person" property="schema:name" datatype="">Renato Rio (not verified)</span> on 27 Aug 2010 <a href="https://scienceblogs.com/taxonomy/term/27899/feed#comment-2210593">#permalink</a></em> <article typeof="schema:Person" about="/user/0"> <div class="field field--name-user-picture field--type-image field--label-hidden field--item"> <a href="/user/0" hreflang="und"><img src="/files/styles/thumbnail/public/default_images/icon-user.png?itok=yQw_eG_q" width="100" height="100" alt="User Image" typeof="foaf:Image" class="img-responsive" /> </a> </div> </article> </footer> </article> <article data-comment-user-id="0" id="comment-2210594" class="js-comment comment-wrapper clearfix"> <mark class="hidden" data-comment-timestamp="1282935564"></mark> <div class="well"> <strong></strong> <div class="field field--name-comment-body field--type-text-long field--label-hidden field--item"><p>@Passerby<br /> As soon as I have sent my last post I saw your comment on Chris Rowan's blog.

Ever since then, I've been noticing that all plots and graphs concerning quakes distribution and lithosphere deformation, as well as rising magmas, exhibit a cork screw / semi helical pattern. Of course, there are many forces at stake here and we don't know exactly how the stuff in the mantle behaves, whether fluid-like or semi-solid, to state precisely if they go "by the book" in either way. But since we are no experts, we're entitled to do some speculation in this non academic forum and get ready for the criticism. I'm too far from giving my own opinion, but trying to gather some information on this.<br /> What I've read so far draws me back from mantle plume and convection currents theories as being the main responsible for plate movement and magma formation and that gravity is still very much to be blamed. But this is a mere intuition on my part and I'm ready to be slapped on my face to be saying such a sacrilege. Passerby is helping us a lot with all the material he has been providing and I hope someday I'll be able to discuss the subject in a less amateur way. So, let him snort at his leisure.

Like the Halmera earthquake, this sequence appears to be linked to the westward subduction of the Philippine plate beneath the Sunda plate, with the earthquakes taking place in a deeply subducted part of the Philippine slab. The extension is probably the result of down dip tension as the slab sinks into the mantle, with the first shock apparently triggering similar events above and below it. </p> <p>But that only whetted our appetite to know why they are occurring at such depth. While it could be stretching and elongation, the fact that they tend to cluster at specific depths was shown by Lurking in his graph and more obviously, in USGS and PHIVOLCs EQ data that we picked up from a secondary source and couple of related papers.</p> <p>That made us wonder about the potential for *structure*, because these same critical depths of clustering were found in other places, like near the Cocos plate.</p> <p>That led to set of references that have, for me, been exciting to read and ponder. For instance, Dr. Courtillot's plume and tectonics map</p> <p><a href="http://www.geolsoc.org.uk/webdav/site/GSL/shared/images/ourviews/plumes/CourtillotHotspots.bmp">http://www.geolsoc.org.uk/webdav/site/GSL/shared/images/ourviews/plumes…</a></p> <p>shows two shallow hot spots, to the east of the subducting Cocos plate, off the coast of Southern Mexico. That could be rising heated and unfolding subducted plate (pleated) that doesn't have the overriding thick continental edge to contend with, so buoyancy, heating convective forces drive it up from shallower depths.

In 1979, nine tourists were killed at the very same crater that made today's explosion by a similar, though more powerful event. What is true is that since a few weeks we've seen a series of smaller explosive events (and collapse) in the Bocca Nuova, especially on 5 July and on 8 August. Normally such explosions occur when magma rises in the conduit and encounters fluids, and my best bet is that sometime within the next few days, or weeks, or maybe months, we will see new magma appear within the Bocca Nuova, as happened also in the summer of 1995 after more than 2 years of quiescence. There are frequent explosions also within the Northeast Crater, which is another of the four summit craters. These explosions are still very deep and you will not see any material being thrown out because it is happening presumably at a few hundred meters of depth. But you do hear these explosions when on the rim of the crater, and they appear to be growing in frequency and strength.<br /> So the signs are that magma is rising within the conduits leading up to the summit craters, and hopefully we will see some spectacular activity there before a new flank eruption will rip open one side of the mountain and stress the hell out of us and everybody else involved.</p> <p>I have posted some photos on my Flickr page: <a href="http://www.flickr.com/photos/etnaboris">www.flickr.com/photos/etnaboris</a></p> </div> <drupal-render-placeholder callback="comment.lazy_builders:renderLinks" arguments="0=2210515&amp;1=default&amp;2=en&amp;3=" token="oqXLrbBlhReeVuOr_J-aQtTBO9YtWK_CceGA9PQzdKY"></drupal-render-placeholder> </div> <footer> <em>By <a rel="nofollow" href="http://www.ct.ingv.it" lang="" typeof="schema:Person" property="schema:name" datatype="" content="Boris Behncke, Catania, Italy">Boris Behncke,… (not verified)</a> on 25 Aug 2010 <a href="https://scienceblogs.com/taxonomy/term/27899/feed#comment-2210515">#permalink</a></em> <article typeof="schema:Person" about="/user/0"> <div class="field field--name-user-picture field--type-image field--label-hidden field--item"> <a href="/user/0" hreflang="und"><img src="/files/styles/thumbnail/public/default_images/icon-user.png?itok=yQw_eG_q" width="100" height="100" alt="User Image" typeof="foaf:Image" class="img-responsive" /> </a> </div> </article> </footer> </article> <article data-comment-user-id="0" id="comment-2210516" class="js-comment comment-wrapper clearfix"> <mark class="hidden" data-comment-timestamp="1282745372"></mark> <div class="well"> <strong></strong> <div class="field field--name-comment-body field--type-text-long field--label-hidden field--item"><p>Ok.

Heaven had a radius about ninety percent that of PreEarth. These two, initially comprised a binary system (just like the Earth and Moon presently comprise a binary system) orbiting the Sun.</p> <p>Like a bullet rips through the skin of an apple, leaving most of the skin unscathed, Heaven crashed through the crust of PreEarth, taking most of its energy into the interior, while leaving much of the crust unscathed. Now, imagine that the mass of the apple and bullet are so large (planet sized) that the bullet cannot escape their combined gravity. Then you have the hypothesized situation. Of course, as PreEarth swallowed Heaven, it greatly expanded in size. This expansion, however, did not leave the remaining crust unscathed.</p> <p><b><i>The Evidence:</i></b></p> <p><b>1)</b> The hole in the Earth where the planet Heaven entered, i.e., the north west Pacific.<br /><b>2)</b> The impact mountains around the Pacific Ocean, i.e., the ring of fire.<br /><b>3)</b> Western impact mountains ripped off continental block.<br /><b>4)</b> The impact caused continental drift.<br /><b>5)</b> The theory predicts a single circular continent with splits, i.e., Pangaea.<br /><b>6)</b> The theory predicts oceanic crust very different from continental crust.<br /><b>7)</b> Warren Carey's evidence, is also evidence for this hypothesis.<br /><b>8</b><b>)</b> Apparent sea-floor ages explained as geochemical gradient due to mixing.<br /><b>9)</b> The theory predicts Earth's core is rotating faster than its mantle.<br /><b>10)</b> The theory predicts Earth's magnetic field is rapidly decreasing.<br /><b>11)</b> The theory predicts/explains magnetic reversals.<br /><b>12)</b> The theory allows the force of gravity to have been smaller in the past.<br /><b>13)</b> Removes the thermal catastrophe.<br /><b>14)</b> The theory provides a decent power source for continental drift.<br /><b>15)</b> Animations of the expansion plus drift can be produced.<br /><b>16)</b> Provides a new theory regarding the formation of the Moon.</p> <p>See <a href="http://preearth.net/evidence.html">http://preearth.net/evidence.html</a> where each point above is expanded upon:</p> <p><b><i>A brief history of the ideas.</i></b></p> <p>Many of the ideas above were first presented in a public lecture, on November 2, 2008, at the Alexandra Park Raceway, Auckland, New Zealand.

There have been a few more, but smaller, explosions, from the Bocca Nuova last night. No large rocks have been ejected, just ash, and the material appears to be a lot of old, altered rock with maybe a minor fraction of new magmatic material.</p> <p>@Jón FrÃmann, the signals that you see on the ESVO seismograms are explosion signals, caused by the deep explosions within the Northeast Crater. These have been occurring, though less frequently and less strongly, for many months. It is a very typical sign of Strombolian activity. But certainly the gradual increase indicates that magma may be rising within the conduit of the Northeast Crater. This is, so to say, Etna's most typical business.</p> <p>@Carl on Etna #28, the latest explosions were from the Bocca Nuova, but the Northeast Crater has continous deep explosions since a while.<br /> Catania has never, not one single time, been destroyed completely by lava flows. It has been threatened on a number of occasions, and its western outskirts were destroyed in 1669, but not its center. Today it would be far more difficult for a lava flow to reach the center of the town and the harbor, because of the multitude of multistorey buildings in reinforced concrete that constitute Catania's suburbs. These would provide a serious obstacle for a lava flow, which cannot be simply overrun or broken down by a lava flow.</p> <p>In any case there are no signs that at Etna a major destructive eruption is imminent (that would mean, a flank eruption from low elevation). What I consider the most likely scenario is that in the next few weeks to months we will see a gradual reactivation of the summit craters, and then for some time - which may be months to years - summit eruptions, which are the most beautiful thing one can imagine, and they are not a threat to populated areas and human property. They might occasionally disrupt air traffic, because they can release significant quantities of ash.</p> <p>Then, as more magma usually rises into the volcano's feeder system than exits from its summit craters, the mountain will gradually swell and become more unstable, and this will be recognized by the seismic activity and by the deformation monitoring, as well as gas emissions. In case of a major flank eruption - especially one from low on the flanks - there will possibly many weeks of premonitory deformation and seismicity, as was the case before the last eruption of this kind, in 1669.</p> <p>The worst scenario we're imagining is a flank eruption that develops extremely fast and emits lava at very high rates, as in 1981, when lava initially travelled at a speed of 3 km per hour - and the nearest population centers were 7 km away. Luckily in that case the lava passed between two villages. That was on the sparsely populated northwest side of Etna, near the town of Randazzo. An eruption of this type on the very densely populated southeast side would be an enormous challenge.</p> <p>Funny anyway how I just posted that big Etna story one week ago and now the volcano is getting a bit more active.</p> <p>I will keep you informed ...</p> </div> <drupal-render-placeholder callback="comment.lazy_builders:renderLinks" arguments="0=2210550&amp;1=default&amp;2=en&amp;3=" token="owk1vPvVmuxhEPqeyRI1NGOGzIpTA3GhEEGbfeSZc40"></drupal-render-placeholder> </div> <footer> <em>By <a rel="nofollow" href="http://www.ct.ingv.it" lang="" typeof="schema:Person" property="schema:name" datatype="" content="Boris Behncke, Catania, Italyb">Boris Behncke,… (not verified)</a> on 26 Aug 2010 <a href="https://scienceblogs.com/taxonomy/term/27899/feed#comment-2210550">#permalink</a></em> <article typeof="schema:Person" about="/user/0"> <div class="field field--name-user-picture field--type-image field--label-hidden field--item"> <a href="/user/0" hreflang="und"><img src="/files/styles/thumbnail/public/default_images/icon-user.png?itok=yQw_eG_q" width="100" height="100" alt="User Image" typeof="foaf:Image" class="img-responsive" /> </a> </div> </article> </footer> </article> <article data-comment-user-id="0" id="comment-2210551" class="js-comment comment-wrapper clearfix"> <mark class="hidden" data-comment-timestamp="1282831280"></mark> <div class="well"> <strong></strong> <div class="field field--name-comment-body field--type-text-long field--label-hidden field--item"><p>Eyjafjöll has a nice big plume today ..</p> <p>I guess thats only water from the crater that has made its way inside the crater..</p> <p>it looks nice tough in the sunlight..</p> </div> <drupal-render-placeholder callback="comment.lazy_builders:renderLinks" arguments="0=2210551&amp;1=default&amp;2=en&amp;3=" token="0OgoiQFyKwIEb5w5QYsOPxG1winBGYG2XT-qbeLV5l8"></drupal-render-placeholder> </div> <footer> <em>By <span lang="" typeof="schema:Person" property="schema:name" datatype="">thor (not verified)</span> on 26 Aug 2010 <a href="https://scienceblogs.com/taxonomy/term/27899/feed#comment-2210551">#permalink</a></em> <article typeof="schema:Person" about="/user/0"> <div class="field field--name-user-picture field--type-image field--label-hidden field--item"> <a href="/user/0" hreflang="und"><img src="/files/styles/thumbnail/public/default_images/icon-user.png?itok=yQw_eG_q" width="100" height="100" alt="User Image" typeof="foaf:Image" class="img-responsive" /> </a> </div> </article> </footer> </article> <article data-comment-user-id="0" id="comment-2210552" class="js-comment comment-wrapper clearfix"> <mark class="hidden" data-comment-timestamp="1282831965"></mark> <div class="well"> <strong></strong> <div class="field field--name-comment-body field--type-text-long field--label-hidden field--item"><p>@Boris Behncke, Catania, Italy.

There is no gas emission from any of the craters on the flanks (except those formed in 2001, 2002-2003, and 2008-2009, which will remain hot still for a few years to come). There are areas of diffuse carbon dioxide emission especially in the valleys above the town of Zafferana, but those areas are now well known and are not open to development (construction, agriculture).</p> <p>Many of the cones and craters on the sides of Etna are already private property - but most of them are on the territory of the Etna Natural Park, where construction is either totally prohibited or allowed only in a very rudimentary way. So I would rather propose some place lying on a ridge or on a hill rather than in a valley - unfortunately in recent years much development has taken place in valleys, and these are at high risk from lava flow invasion during future eruptions. So those areas are no-no for anybody interested in moving to Etna.</p> <p>I do actually like a lot sitting on my terrace watching Etna with a good beer or a good red wine produced on Etna - and our home village sits on a little old cone and thus is more protected than many other areas.</p> <p>For the moment there is no visible activity at Etna except for vigorous gas emission, sometimes rhythmic, and numerous small explosion quakes.

I listened a profound but not loud sound and immediately appeared a brown and white cloud of ash like a mushrom. I didn't see nothing more because I ran down the slope as quick as I could. Three minutes later I turned for the first time and I was very impressed by the enormous dark mushrum that was over me. Luckely the wind was flowing in the opposite direction and I saw a gentil man that was waiting for me at the base and the bus of the funivia that was collecting people. I'm very impressed.

This is one of the reasons why video game localization - as opposed to translation- is a must for video games.</p> <p>That said, these facts raise an important questions: when does the "localization" of content stop being "localization" and turn into full-on "censorship"? And is that something one should accept?</p> <p>As a recent example, Yakuza 3 on PS3 shows well how thin the frontier between censorship and localization can be. A lot of gamers complained because some scenes and important elements of the games where changed when the game made it to US.</p> <p>Now the question is: do all of these elements actually required to be changed? Isn't that just based on a stereotype that American gamers tend to be more religious and concerned about nudity and violence? Gamers were most likely expecting something different after reading about the game in specialized media</p> <p>Now if you look at it, most gamers actually are adult and will absolutely not care to find certain elements.

I'm not sure how often it will run, but let's give it a try.</p> <p><em>Eruptions Word of the Day</em> for July 5, 2010: <strong><a href="http://vulcan.wr.usgs.gov/LivingWith/VolcanicPast/Notes/dacite.html">Dacite</a></strong><br /> Dacite is a magma type defined by silica (SiO<sub>2</sub>) content between 63-68 (or 69) weight percent. That is the textbook definition, but some other typical characteristics of dacite lavas (or magmas) is the presence of certain minerals: plagioclase feldspar and hydrous minerals (containing water in their mineral structure) such as amphibole (typically hornblende) or biotite mica. If the dacite is hot and dry (lacking in water), you would expect to find pyroxene in the lava as well, although it is common in almost all dacites that even have hydrous minerals. Typically, dacite erupt anywhere from 800 to 1000 degrees Celsius. The intrusive equivalent for a dacite is <a href="http://csmres.jmu.edu/geollab/fichter/IgnRx/GranoDio-1A1.html" target="_blank">granodiorite</a>.</p> <p><img src="http://flexiblelearning.auckland.ac.nz/rocks_minerals/rocks/images/dacite.jpg" width="400" /> </p> <p><em>Dacite lava hand sample, with abundant amphibole and plagioclase feldspar.</em></p> <p>Dacite is found in <a href="http://www.sciencedirect.com/science?_ob=ArticleURL&amp;_udi=B6VCS-4HYN542-3&amp;_user=10&amp;_coverDate=04%2F15%2F2006&amp;_rdoc=1&amp;_fmt=high&amp;_orig=search&amp;_sort=d&amp;_docanchor=&amp;view=c&amp;_searchStrId=1390390635&amp;_rerunOrigin=google&amp;_acct=C000050221&amp;_version=1&amp;_urlVersion=0&amp;_userid=10&amp;md5=c513f7d4003b2d1dc676a3b3ea860296" target="_blank">a wide variety</a> of tectonic settings but is most common in <a href="http://www.springerlink.com/content/c153884837m74283/" target="_blank">continental subduction zone/arc settings</a>, such as the Andes or the Cascades. They tend to be products of <a href="http://petrology.oxfordjournals.org/cgi/content/short/40/1/105" target="_blank">magma mixing</a> or crustal assimilation (by another magma) to form the dacite. The types of eruptions that dacite magma produces can vary from lava flows and domes (effusive, passive eruptions) to explosive, plinian-style eruptions - but they are most famous for the explosive eruptions like <a href="http://www.geology.sdsu.edu/how_volcanoes_work/Sthelens.html" target="_blank">Mount St. Helens</a>, <a href="http://vulcan.wr.usgs.gov/Volcanoes/Lassen/description_lassen.html" target="_blank">Lassen Peak</a> and <a href="http://geology.geoscienceworld.org/cgi/content/abstract/23/9/807" target="_blank">Unzen</a> in Japan (see below).</p> <p><img src="http://top-10-list.org/wp-content/uploads/2009/04/volcano-unzen.jpg" width="400" /> </p> <p><em>Pyroclastic flows from Mt. Unzen in Japan. A flow like this killed the Kraffts in 1991.</em></p> <p>However, there are impressive effusive dacite lavas flows, such as the <a href="http://volcano.oregonstate.edu/oldroot/CVZ/chao/index.html" target="_blank">Chao Dacite</a> and <a href="http://www.springerlink.com/content/an40117441822131/" target="_blank">Volcan Aucanquilcha</a> (see below) in Chile and <a href="http://www.craterlakeinstitute.com/natural-history/geology-llao-rock.htm" target="_blank">Llao Rock at Crater Lake</a>, where minor explosive deposits preceded the lava flows that stretch upwards of 5-10 km from the vent. These lava flows are usually steep-sided with well-formed levees on the sides and pressure ridges along the flow tops (see below). It is thought that dacite lava flows or domes form when the magma is allowed to degas before erupting, allowing for a passive rather than explosive eruption.</p> <p><a href="http://scienceblogs.com/eruptions/aucan_flows_2.jpg"><img src="http://scienceblogs.com/eruptions/wp-content/blogs.dir/312/files/2012/04/i-442189f7b606d93f171446d267418a0b-aucan_flows_2-thumb-400x197-52468.jpg" alt="i-442189f7b606d93f171446d267418a0b-aucan_flows_2-thumb-400x197-52468.jpg" /></a></p> <p><a href="http://scienceblogs.com/eruptions/aucan_flows_2.jpg"></a><br /><em>Dacite lava flows on Volcan Aucanquilcha, Chile.

Image by Erik Klemetti.</em></p> <p>Dacite tend to be a "garbage bag" of minerals - they have collected a variety of crystals from different sources. These sources include the active magma of the eruption in question (<em>phenocrysts</em>), crystals from previous magmatism at the volcano (<em>antecrysts</em>) and wholly unrelated crystals (<em>xenocrysts</em>). This mixing creates disequilibrium, where minerals only stable in one condition find themselves in another, creating impressive reaction textures (see below). This variety of crystals supports the ideas that many dacites are the product of magma mixing.</p> <p><a href="http://scienceblogs.com/eruptions/0203_chileek_001.jpg"><img src="http://scienceblogs.com/eruptions/wp-content/blogs.dir/312/files/2012/04/i-43d0a0d1369418c3b769fb8dc598ecde-0203_chileek_001-thumb-400x320-52466.jpg" alt="i-43d0a0d1369418c3b769fb8dc598ecde-0203_chileek_001-thumb-400x320-52466.jpg" /></a> </p> <p><em>Amphibole crystal breaking down in a mixed dacite from Volcan Aucanquilcha, Chile.

It's just like being an undergrad again. No wonder I was happy then, with the earth divided into reasonable chunks of rock and unreasonable time periods. There's something so comforting about mineralogy and petrology and all matters geologic in a world of idiotic politics, wars, and pop culture. I'm serious! Whenever I feel confused I go out in the field and ponder erosion features, stream gradients, and rubble deposits, and lug home metamorphic cobbles, which are the most mysterious objects I know of.

Great idea to have the definitions and pictures of what you are talking about. Although I took geology, that was forty years ago and I have forgotten a lot of it.</p> <p>@Bo Moore #5, I can't agree with you more! My DH and I like to go to the river early when no one else is there and it is so peaceful. We like to pan for gold and check out the rock in the river. We see a lot of different things in the river such as lava bombs and jasper. A lot of quartz and limestone. Once in a while you will have a really cool find as I did at a confluence of two forks of the river: a fairly large rock of yellow jasper. I intended to take it out and forgot it. I could kick myself for that one.</p> <p>I have a metamorphic rock I took out of an ignious dike. I showed it to my geology teachers and they told me it was metamorphic and when I told them where I got it, they didn't believe me. The dike was a place they sent all of us to see what it was like and I found that rock in the dike. It was different and I kept telling them it was from the dike.

He believed the stone to be the source of all his recent calamities. The lava has now been returned, flown by helicopter to the eruption site at Eyjafjallajökull glacier.</p> <p>After suffering blows both in his private and professional life, the tourist decided to send the nugget to the University of Icelandâs Institute of Earth Sciences, requesting that it be returned to its proper place.</p> <p>âHe was not joking,â said Rikke Pedersen, a specialist at the institution. âHe had been traveling around Iceland with his family and since then, all kinds of bad things began happening to him. He was convinced that if he returned the nugget, everything would return to normal.â<br /> Pedersen received the rock along with a letter explaining the situation. This week, she brought it to the Iceland Tourist Assistance. There, the staff got in touch with Nordurflug Flight Company who flew it to the eruption site, which contains Icelandâs freshest lava.</p> <p>In Iceland, rocks are part of the folklore.</p> </div> <drupal-render-placeholder callback="comment.lazy_builders:renderLinks" arguments="0=2208074&amp;1=default&amp;2=en&amp;3=" token="vSSEWuIOToYVsBCtKS7KnSTwD9rwPhuPNacqTJB5fKw"></drupal-render-placeholder> </div> <footer> <em>By <span lang="" typeof="schema:Person" property="schema:name" datatype="">birdseye USA (not verified)</span> on 05 Jul 2010 <a href="https://scienceblogs.com/taxonomy/term/27899/feed#comment-2208074">#permalink</a></em> <article typeof="schema:Person" about="/user/0"> <div class="field field--name-user-picture field--type-image field--label-hidden field--item"> <a href="/user/0" hreflang="und"><img src="/files/styles/thumbnail/public/default_images/icon-user.png?itok=yQw_eG_q" width="100" height="100" alt="User Image" typeof="foaf:Image" class="img-responsive" /> </a> </div> </article> </footer> </article> <article data-comment-user-id="0" id="comment-2208075" class="js-comment comment-wrapper clearfix"> <mark class="hidden" data-comment-timestamp="1278329927"></mark> <div class="well"> <strong></strong> <div class="field field--name-comment-body field--type-text-long field--label-hidden field--item"><p>Excellent! like #4 this is a nice escape into the world of an<br /> undergrad, I almost switched my major to Geology, but didn't.<br /> I probably wouldn't have used the Degree anyway like I didn't use my B.S. in Biology...</p> </div> <drupal-render-placeholder callback="comment.lazy_builders:renderLinks" arguments="0=2208075&amp;1=default&amp;2=en&amp;3=" token="kSHbn6Rux0tIpEhdkwF7o98ARk5sMNagfTwpFWdo8l4"></drupal-render-placeholder> </div> <footer> <em>By <span lang="" typeof="schema:Person" property="schema:name" datatype="">GT McCoy (not verified)</span> on 05 Jul 2010 <a href="https://scienceblogs.com/taxonomy/term/27899/feed#comment-2208075">#permalink</a></em> <article typeof="schema:Person" about="/user/0"> <div class="field field--name-user-picture field--type-image field--label-hidden field--item"> <a href="/user/0" hreflang="und"><img src="/files/styles/thumbnail/public/default_images/icon-user.png?itok=yQw_eG_q" width="100" height="100" alt="User Image" typeof="foaf:Image" class="img-responsive" /> </a> </div> </article> </footer> </article> <article data-comment-user-id="0" id="comment-2208076" class="js-comment comment-wrapper clearfix"> <mark class="hidden" data-comment-timestamp="1278330164"></mark> <div class="well"> <strong></strong> <div class="field field--name-comment-body field--type-text-long field--label-hidden field--item"><p>&gt;I have a metamorphic rock I took out of an igniousigneous dike</p> <p>Could be evidence of contact metamorphism, where hot igneous intrusion(some 1200 degrees C) heats host rock, transforming it.

As a quick answer: yes and no. I'll start with the "no" - the molecular water in the crystalline structure doesn't directly take part in making an eruption explosive as such as it is bound up in the crystal (not as bubbles in the mineral or magma). However, usually it takes higher water content in the magma (as bubbles when they exsolve/come out of solution) for these minerals to form in the first place, so the "yes" is that hydrous minerals are a marker for water/volatile-rich magma.</p> </div> <drupal-render-placeholder callback="comment.lazy_builders:renderLinks" arguments="0=2208077&amp;1=default&amp;2=en&amp;3=" token="iC-1Bhzf61J6Si_cRFYKZayj5f1biw7BdbfhckJf17k"></drupal-render-placeholder> </div> <footer> <em>By <a title="View user profile." href="/author/eklemetti" lang="" about="/author/eklemetti" typeof="schema:Person" property="schema:name" datatype="">eklemetti</a> on 05 Jul 2010 <a href="https://scienceblogs.com/taxonomy/term/27899/feed#comment-2208077">#permalink</a></em> <article typeof="schema:Person" about="/author/eklemetti"> <div class="field field--name-user-picture field--type-image field--label-hidden field--item"> <a href="/author/eklemetti" hreflang="en"><img src="/files/styles/thumbnail/public/default_images/icon-user.png?itok=yQw_eG_q" width="100" height="100" alt="User Image" typeof="foaf:Image" class="img-responsive" /> </a> </div> </article> </footer> </article> <article data-comment-user-id="0" id="comment-2208078" class="js-comment comment-wrapper clearfix"> <mark class="hidden" data-comment-timestamp="1278334192"></mark> <div class="well"> <strong></strong> <div class="field field--name-comment-body field--type-text-long field--label-hidden field--item"><p>Often or not, useful most certainly.</p> <p>Aside: Up here, 'lÃparÃt' (derived from Lipari) is a term used for silica-rich types like rhyolite, dacite and benmoreite, according to a glossary my sister bought last week.</p> </div> <drupal-render-placeholder callback="comment.lazy_builders:renderLinks" arguments="0=2208078&amp;1=default&amp;2=en&amp;3=" token="Shg9jxApGf0b8iMfLtlY_YCiWvx8QLBF26UTmDnXUVI"></drupal-render-placeholder> </div> <footer> <em>By <span lang="" typeof="schema:Person" property="schema:name" datatype="">Reynir, NK, .is (not verified)</span> on 05 Jul 2010 <a href="https://scienceblogs.com/taxonomy/term/27899/feed#comment-2208078">#permalink</a></em> <article typeof="schema:Person" about="/user/0"> <div class="field field--name-user-picture field--type-image field--label-hidden field--item"> <a href="/user/0" hreflang="und"><img src="/files/styles/thumbnail/public/default_images/icon-user.png?itok=yQw_eG_q" width="100" height="100" alt="User Image" typeof="foaf:Image" class="img-responsive" /> </a> </div> </article> </footer> </article> <article data-comment-user-id="0" id="comment-2208079" class="js-comment comment-wrapper clearfix"> <mark class="hidden" data-comment-timestamp="1278336640"></mark> <div class="well"> <strong></strong> <div class="field field--name-comment-body field--type-text-long field--label-hidden field--item"><p>#15 Thank, you Erik.

The idea that a vortex could become self generating by pulling in colder mantle material and then warming it by friction makes some sort of sense. Hurricanes can grow by pulling in warm air from the water surface, and firestorms, manmade or natural, by pulling in cold oxygen rich air to fuel the central combustion. Both are vortices but in a different medium and timescale.</p> </div> <drupal-render-placeholder callback="comment.lazy_builders:renderLinks" arguments="0=2208084&amp;1=default&amp;2=en&amp;3=" token="fU3tg_mLhPmIDwk196A5SqaNhWk8C7J9B0lNObM2_vA"></drupal-render-placeholder> </div> <footer> <em>By <span lang="" typeof="schema:Person" property="schema:name" datatype="">Gordon (not verified)</span> on 05 Jul 2010 <a href="https://scienceblogs.com/taxonomy/term/27899/feed#comment-2208084">#permalink</a></em> <article typeof="schema:Person" about="/user/0"> <div class="field field--name-user-picture field--type-image field--label-hidden field--item"> <a href="/user/0" hreflang="und"><img src="/files/styles/thumbnail/public/default_images/icon-user.png?itok=yQw_eG_q" width="100" height="100" alt="User Image" typeof="foaf:Image" class="img-responsive" /> </a> </div> </article> </footer> </article> <article data-comment-user-id="0" id="comment-2208085" class="js-comment comment-wrapper clearfix"> <mark class="hidden" data-comment-timestamp="1278376645"></mark> <div class="well"> <strong></strong> <div class="field field--name-comment-body field--type-text-long field--label-hidden field--item"><p>Great idea Erik.

The results was pretty odd, but that picture actually showed that I at least am not that totally off and that you can use the ice-modell for calculating the fluid motion patterns of Iceland out of it.

A new line should soon (geologically speaking) open up from the northern tip of the WVZ to Kolbinsöy-ridge since the pent up east to west-skewing energy is to large in the Reykjaness Peninsula to Hekla area to be contained for long. When and if that happens there will probably be an epoch of rapid tectonic movement as the pent up stresses quickly releases, partnered with very large magmatic release. Something that probably happened back when the Reykjanes Ridge to Grimsvötn opened up.

The figures I used for the pent up energy is to be found here:<br /><a href="http://hraun.vedur.is/ja/skyrslur/June17and21_2000/index.html">http://hraun.vedur.is/ja/skyrslur/June17and21_2000/index.html</a></p> <p>I then recalculated those nombers as a whole for the RR to Grimsvötn line.</p> <p>That pent up energy gives the energy potential for the Vestmannaeyjar to to Kolbinsöy line and the WVZ combined. The pent up tension-stress is of course translated into negative values since we are here talking of something as basic as suction when the parts are pulled apart.<br /> When Ice is torn apart water is pulled up into the crack by this suction-force, here it is magma pulled up, but the principle is the same.</p> <p>Then we can go into simple fluid dynamics. A rule of thumb is that we will get small vorticii in the water sucked up and that these will be spread out evenly if the fracture is straight-lined. If it is not we will get differently sized Vorticii. The power of the vortex increases with the angle of any corner-structure in the ice, and if the corner is at 90 degrees the vortex will be squared compared to a straight-line vortex. In this case we have 2 (almost) 90 degree corners adding up the power. The vortex thusly created is so powerfull that it can and will controll any other vorticii in the straight-line zone that is ripping apart.<br /> I am not here going to explain why vorticii is always going to start in fluid dynamics, that is really school-book physics and I am pressed for time today.</p> <p>So what is so wonderfull with a Vortix?<br /> Well it can explain a few things. If a vortex like that exists (remember that this is a theoretical modell based on fluid dynamics using calculations normally used on Ice and water, not magma) it explains a few things and makes one prediction (possible to falsify).<br /> The pent up energy in the RR to Grimsvötn line is large enough to sustain a vortex streatching from Grimsvötn up to Askja, the spead of outer edge movement would be 10cm a year, and it sucks up an average of five centimetres of magma per year, and the area is large so we are talking about something rather massive here. That sucked up magma then spreads out from the Vortex when it hits the crust. When I did the first calculations I got a number for how much Iceland could be sucked up to be between 25 to 100 metres. Then someone posted a link from BBC that gave the actual number to be 50 metres.</p> <p>(Next instalment, What does Vorticiis have to do with Volcanos?)</p> </div> <drupal-render-placeholder callback="comment.lazy_builders:renderLinks" arguments="0=2207888&amp;1=default&amp;2=en&amp;3=" token="fGB5SNJbKVmeOkMrTs2d32kOAbuiQ921eQwd9lx_DWI"></drupal-render-placeholder> </div> <footer> <em>By <span lang="" typeof="schema:Person" property="schema:name" datatype="">Carl (not verified)</span> on 01 Jul 2010 <a href="https://scienceblogs.com/taxonomy/term/27899/feed#comment-2207888">#permalink</a></em> <article typeof="schema:Person" about="/user/0"> <div class="field field--name-user-picture field--type-image field--label-hidden field--item"> <a href="/user/0" hreflang="und"><img src="/files/styles/thumbnail/public/default_images/icon-user.png?itok=yQw_eG_q" width="100" height="100" alt="User Image" typeof="foaf:Image" class="img-responsive" /> </a> </div> </article> </footer> </article> <article data-comment-user-id="0" id="comment-2207889" class="js-comment comment-wrapper clearfix"> <mark class="hidden" data-comment-timestamp="1278044951"></mark> <div class="well"> <strong></strong> <div class="field field--name-comment-body field--type-text-long field--label-hidden field--item"><p>Grimsvötn-Askja Vortex Plume, part 3</p> <p>So what did this all have to do with a Volcano?<br /> Well, a large vortix sucking up water is not so bad when we are talking about fracturing ice. But things change if we add one factor. Let's say that it is really cold and that the water in the fracture almost emediatly freezes over creating a new (thinner) ice-layer. That is what is happening here, almost emediatly the upwelling magma cools of and solidifies into new crust. But the water, sorry magma is still welling up and wants to surface. And it will at the weakest points, and those will be found where the outer edge of the vortix (fastest moving, highest energy) meet the fracture in the ice.<br /> In this case that would be the Grimsvötn volcanic system and the volcanic system around Askja.</p> <p>Sub-vorticii:<br /> Any main vortix will dominate any other vortix that is along the straight-line fracture. There is a mathematical rule that tells us that from a large vortix there will be subvorticiis in a progression outwards and that those are calculable to be the power potential times (in relation) both distance and sub-energy-potential and that is relative to the mathematical irrational constant of approximately 1.6180339887 (I know, but nature really loves that one).<br /> When you calculate it the main southern sub-vortix would be quite a distance away around where one finds Katla. (The same proportionality actually goes for Katlas little slave vortix Eyjafjallajökull.) The main subvortix is about one quarter in energy potential to the Main-vortex (give or take 25 percent). So that is why E has one quarter of Ks energy-potential, next in line would be Heimöy then.<br /> Northward we have Krafla and so on.</p> <p>So what has this to do with a plume?<br /> Well the suction force is so large that it will start a very deep-going vortix. If you want to you can see it as an inverted tornado, sucking up magma from far below (ground) up to the surface (cloud). Albeit here surface is the core boundary and the surface is either crust or actual surface during an eruption. </p> <p>This gives that we are here talking about a plume that is actually generated at the surface, and not at the bottom as the standard modell plumes generating heatspots. The standard modell plumes move over time so you get timelined volcanos (Hawaii for instance) as the heatspot generated by the plume moves since the plume is "anchored" to the bottom at the core boundary.<br /> Here instead we are talking about a plume that (for now at least) is anchored to the surface, that is why we are not seeing any timelined volcanos on Iceland. Though we are seeing timelined volcano-bands as I talked about in part 1.</p> <p>Now someone will probably say that Grimsvötn and Askja has different magmatic composition, and that is probably true. Does this falsify the theory? No, not really. One has to keap in mind that we are talking about a large slowly turning (in human time-understanding) vortex that is succing magma over a large distance of depth, in that vortix you are bound to have "globs" of different origin. But if someone finds lava that is wildly out of line it probably would put the entire theory in jeopardy (I suspect Eric will shot this theory in the foot about here).</p> <p>So, what does this help? Well, if one want to one can calculate the tension-break points for the intersections of the fractures and the vorticiis. There is probably a pretty distinct height that those parts of Iceland can stand before breaking. Let's say that Askja can be lifted 10cm before magma is pushed up starting an eruption. That number would have to be calculated from the zero level and not todays plus 50 number, but that is just a small problem mathematically. The real problem is to calculate with any grade of exactitude the point of breaking for Askja.<br /> But, when an area is lifted enough it will erupt, release enough of lava to lower to magma level-pressure untill the vortix has moved and sucked up new magma and it all starts over again. </p> <p>My guess is that this entire area is allways very close to the breaking point and that is why the period of increasing signs of eruption is in many cases so short on iceland. Just think about it, if all that is neaded is a couple of centimetres over a (comparatively) small area just one little wave can tip the waggon and start an eruption in minutes.</p> <p>It wass rather fun to think about this, I am probably wrong, and you are all welcome to shot me in the fot now. I am sorry though that I didn't have time to write a proper paper about this presenting the graphs for it, and of course the mathematical formulae, but I guess that most of you can deduce those on your own.</p> <p>Oh, and thanks Lurking (whomever you might be) for that wonderfull image showing the vorticiis of "Grimsvötn-Askja", Katla and the sub-slave Eyjafjallajökull.<br /><a href="http://i48.tinypic.com/n2ykax.png">http://i48.tinypic.com/n2ykax.png</a></p> <p>Oh, and by the way, if I should do a prediction out of this my little theory, it would be that the likelyhood of the next eruption on Iceland would be either around Grimsvötn or Askja, and the statistical likelihood is 42 percent and that the apparant pent up energy is large, so that would probably be a VEI-3 or larger and will release a larger than average amount of lava. The likelihood of this happening within 15 years is 73 percent.<br /> But the margins for error is massive since I haven't been able to calculate the fracture points...</p> </div> <drupal-render-placeholder callback="comment.lazy_builders:renderLinks" arguments="0=2207889&amp;1=default&amp;2=en&amp;3=" token="1o_mX2IPqUdxJsRoqxNEyR4WsmYOjq-DfIE7vL_2U0U"></drupal-render-placeholder> </div> <footer> <em>By <span lang="" typeof="schema:Person" property="schema:name" datatype="">Carl (not verified)</span> on 02 Jul 2010 <a href="https://scienceblogs.com/taxonomy/term/27899/feed#comment-2207889">#permalink</a></em> <article typeof="schema:Person" about="/user/0"> <div class="field field--name-user-picture field--type-image field--label-hidden field--item"> <a href="/user/0" hreflang="und"><img src="/files/styles/thumbnail/public/default_images/icon-user.png?itok=yQw_eG_q" width="100" height="100" alt="User Image" typeof="foaf:Image" class="img-responsive" /> </a> </div> </article> </footer> </article> <article data-comment-user-id="0" id="comment-2207890" class="js-comment comment-wrapper clearfix"> <mark class="hidden" data-comment-timestamp="1278051492"></mark> <div class="well"> <strong></strong> <div class="field field--name-comment-body field--type-text-long field--label-hidden field--item"><p>@Carl That makes sense to me, though I'm no expert, and it would explain the strange "mantle plume" behavior ("the plume is "anchored" to the the surface" ).<br /> I have my own inferred suspicions that next eruption was to take place in the region you mentioned, just didn't know why.

There is not a vast ocean of magma beneath the crust. The mantle beneath the crust is crystalline rock, but it does flow (as a solid) very slowly at the correct pressures and temperatures.<br /> Where plates pull apart(such as in Iceland), what is pulling apart is the crust with the very top part of the mantle. Deeper mantle will well up into the area and the rock will melt a bit as it rises. That's the source of the magma.<br /> Iceland has more melting and heat flow than the other parts of the Mid-Atlantic ridge, such areas are "hotspots". This hotspot has been attributed to a "mantle plume", which again is not rising hot magma, but solid, crystalline, yet plastic and flowing rock from deep in the Earth.<br /> There is quite a bit of study of mantle flow, geophysics can image it because the mineral crystals deform and align, which affects the behavior of seismic waves passing through.<br /> Also, the plume model for Hawaii assumes the plume is fixed in place, there is a linear chain of islands because the plate moves over it. Imagine holding a pen in one place, pointing up. Then move a paper over it -same idea.</p> </div> <drupal-render-placeholder callback="comment.lazy_builders:renderLinks" arguments="0=2207892&amp;1=default&amp;2=en&amp;3=" token="Ubox_Qx6l4PFkUBJ-IQMTQPYx7B4DFABKCDYRUxpvl0"></drupal-render-placeholder> </div> <footer> <em>By <span lang="" typeof="schema:Person" property="schema:name" datatype="">Ekoh (not verified)</span> on 02 Jul 2010 <a href="https://scienceblogs.com/taxonomy/term/27899/feed#comment-2207892">#permalink</a></em> <article typeof="schema:Person" about="/user/0"> <div class="field field--name-user-picture field--type-image field--label-hidden field--item"> <a href="/user/0" hreflang="und"><img src="/files/styles/thumbnail/public/default_images/icon-user.png?itok=yQw_eG_q" width="100" height="100" alt="User Image" typeof="foaf:Image" class="img-responsive" /> </a> </div> </article> </footer> </article> <article data-comment-user-id="0" id="comment-2207893" class="js-comment comment-wrapper clearfix"> <mark class="hidden" data-comment-timestamp="1278066460"></mark> <div class="well"> <strong></strong> <div class="field field--name-comment-body field--type-text-long field--label-hidden field--item"><p>@Carl. I think your theory is intriguing. I'm not by any means an expert, but I'm pretty good at seeing connections. (think Podkayne of Mars ;-D) As I've been reading the papers over the last few months, it appears that there is no certainty over plume vs MAR as the source of magma. This would explain the confusion-- a vortex. (Albeit very slooooowww). My (current) understanding of the mantle is that it's semi-solid (mushy ice). So I guess the question may be: what's the take of someone who understands fluid dyanamic?</p> <p>I keep thinking that the rotation of the earth has got to be bumping the mantle around so that it circulates like the oceans, and massive earthquakes now and then cause waves through the mantle. Then, these waves hit the equivalent of blow-holes (volcanoes, rifts) and the magma starts rising. Your vortex theory would make the mixing-up of plume magma, MAR magma, and local rock explain the differences between the various lava compositions.</p> <p>Hmm. More thinking and research.</p> </div> <drupal-render-placeholder callback="comment.lazy_builders:renderLinks" arguments="0=2207893&amp;1=default&amp;2=en&amp;3=" token="896jFotiSsm6NFWHj-UD9qoyIhKp5Zsiw-m3zHAgIMQ"></drupal-render-placeholder> </div> <footer> <em>By <span lang="" typeof="schema:Person" property="schema:name" datatype="">parclair NoCal USA (not verified)</span> on 02 Jul 2010 <a href="https://scienceblogs.com/taxonomy/term/27899/feed#comment-2207893">#permalink</a></em> <article typeof="schema:Person" about="/user/0"> <div class="field field--name-user-picture field--type-image field--label-hidden field--item"> <a href="/user/0" hreflang="und"><img src="/files/styles/thumbnail/public/default_images/icon-user.png?itok=yQw_eG_q" width="100" height="100" alt="User Image" typeof="foaf:Image" class="img-responsive" /> </a> </div> </article> </footer> </article> <article data-comment-user-id="0" id="comment-2207894" class="js-comment comment-wrapper clearfix"> <mark class="hidden" data-comment-timestamp="1278068661"></mark> <div class="well"> <strong></strong> <div class="field field--name-comment-body field--type-text-long field--label-hidden field--item"><p>@Ekoh:</p> <p>Yes, I am aware of the semi-solid state of the mantle. Thing is that what we in ordinary life concieve as the "solid" part of the word semi-solid is not at all solid. They are just less viscous than pure non-solids like water. But if you go into the geological scale the difference between a semi-solid like the mantle and the non-solid like water is none at all. The mantle behaves exactly as a fluid in longer timespans. </p> <p>But you are very much correct in me being unclear concerning mantle and magma interaction, I am very much an amateur concerning that. Regarding fluidity in solids, non-solids and semi-solids I am not.<br /> You are also correct in that I knowingly stretched the Ice-water/magma-crust analogy quite a bit, but I tried to explain in things in laymans terms. There are differences, but the fluid dynamic model from ice-water that I used is still quite aplicable for semi-solids interacting with solids. It is as I said, just a question of the timescale, and here we are talking about 100Ks of years...</p> <p>Concerning Hawaii, I wrote that it is fixed in the coreboundary, which if I have understood plume-theory is where it is suposed to be attached, and I wrote that it is the upper part that progresses. What I was probably unclear about is that the plates glide over the mantle, mea culpa:)</p> <p>For those who want a more earthly example of what I am talking about, if you remember your school science you will remember that the flow-rate of silicate-glasses are one millimetre per hundred years in supension-state. And that is counted as a solid since it is in a chrystalline lattice.</p> <p>I am quite certain that the physics is correct, the things I worry about is the geological facts.</p> </div> <drupal-render-placeholder callback="comment.lazy_builders:renderLinks" arguments="0=2207894&amp;1=default&amp;2=en&amp;3=" token="q2i-g5X4fEWZjJ9v7bvMU5HVapPeO2sGEthziB610Jk"></drupal-render-placeholder> </div> <footer> <em>By <span lang="" typeof="schema:Person" property="schema:name" datatype="">Carl (not verified)</span> on 02 Jul 2010 <a href="https://scienceblogs.com/taxonomy/term/27899/feed#comment-2207894">#permalink</a></em> <article typeof="schema:Person" about="/user/0"> <div class="field field--name-user-picture field--type-image field--label-hidden field--item"> <a href="/user/0" hreflang="und"><img src="/files/styles/thumbnail/public/default_images/icon-user.png?itok=yQw_eG_q" width="100" height="100" alt="User Image" typeof="foaf:Image" class="img-responsive" /> </a> </div> </article> </footer> </article> <article data-comment-user-id="0" id="comment-2207895" class="js-comment comment-wrapper clearfix"> <mark class="hidden" data-comment-timestamp="1278069474"></mark> <div class="well"> <strong></strong> <div class="field field--name-comment-body field--type-text-long field--label-hidden field--item"><p>hi does anyone have a link/sat/webcam to show above volcano E would be nice to see above on a clear day</p> </div> <drupal-render-placeholder callback="comment.lazy_builders:renderLinks" arguments="0=2207895&amp;1=default&amp;2=en&amp;3=" token="_qqIAlgQYDMzKL0kSF1Z_zj9NOFOOCINKwJqLgY2LM8"></drupal-render-placeholder> </div> <footer> <em>By <span lang="" typeof="schema:Person" property="schema:name" datatype="">leon (not verified)</span> on 02 Jul 2010 <a href="https://scienceblogs.com/taxonomy/term/27899/feed#comment-2207895">#permalink</a></em> <article typeof="schema:Person" about="/user/0"> <div class="field field--name-user-picture field--type-image field--label-hidden field--item"> <a href="/user/0" hreflang="und"><img src="/files/styles/thumbnail/public/default_images/icon-user.png?itok=yQw_eG_q" width="100" height="100" alt="User Image" typeof="foaf:Image" class="img-responsive" /> </a> </div> </article> </footer> </article> <article data-comment-user-id="0" id="comment-2207896" class="js-comment comment-wrapper clearfix"> <mark class="hidden" data-comment-timestamp="1278071390"></mark> <div class="well"> <strong></strong> <div class="field field--name-comment-body field--type-text-long field--label-hidden field--item"><p>Eyjafj webcam shows past eruptions maybe useful if you have not got, <a href="http://www.vodafone.is/eldgos/en">http://www.vodafone.is/eldgos/en</a></p> </div> <drupal-render-placeholder callback="comment.lazy_builders:renderLinks" arguments="0=2207896&amp;1=default&amp;2=en&amp;3=" token="iYBh-MUbqanPaFG9aGLCURiU9oRSWK3gdo96hZLNcDs"></drupal-render-placeholder> </div> <footer> <em>By <span lang="" typeof="schema:Person" property="schema:name" datatype="">leon (not verified)</span> on 02 Jul 2010 <a href="https://scienceblogs.com/taxonomy/term/27899/feed#comment-2207896">#permalink</a></em> <article typeof="schema:Person" about="/user/0"> <div class="field field--name-user-picture field--type-image field--label-hidden field--item"> <a href="/user/0" hreflang="und"><img src="/files/styles/thumbnail/public/default_images/icon-user.png?itok=yQw_eG_q" width="100" height="100" alt="User Image" typeof="foaf:Image" class="img-responsive" /> </a> </div> </article> </footer> </article> <article data-comment-user-id="0" id="comment-2207897" class="js-comment comment-wrapper clearfix"> <mark class="hidden" data-comment-timestamp="1278074109"></mark> <div class="well"> <strong></strong> <div class="field field--name-comment-body field--type-text-long field--label-hidden field--item"><p>@Carl #36 are you talking about how window glass flows and using that as an analogy for the mantle's crystaline state, yet being able to flow as glass?</p> <p>I am wondering about the vortex idea and how much the rotation of the earth can affect that and also the tilt of the axis. I would expect if there is any affect at all, it would not be dramatic from our perspective, but it may be from a geological perspective. Now what would cause some of the magma to be so fluid it runs like pancake syrup out of a bottle and at other times it is like holding a catcup bottle waiting for something to come out and you end up having to bang on the side or bottom of the bottle to get it to come out? I know it has different chemical make-up. The more silicic it is the more viscous it is. How does your vortex (I think of eddies)theory fit into this senario? Also you have to figure in all the gases that come along with the magma. I would think if there was a lot of gas, it would affect the vorticii. When it boils down to it, we really don't know exactly how things are working below the crust, though we do have some ideas about it based on what we see when there is an eruption and also what we see from studying areas that have had a lot of eruptions.</p> <p>There is so much we don't know and I know you agree with that. I don't have a very good grasp of physics as I did not take it in high school. I did have some in college, but I don't remember anything about water-ice interactions. What I had was just a basic course and then a course called Electron Optics. And all that was 30 years ago. LOL</p> <p>I will say I do know something about vorticii, though, of a different kind. I was taking flying lessons and my instructor and I were coming in for a landing behind a Piper Cherokee or Dakota (I think it was the Dakota) and all at once our little Cessna 152 started bouncing around and behaving sort of weird. I asked my instructor what that was all about and he told me it was the vorticii from the wings of the plane ahead of us. I can tell you I did not like that at all. I have been told that a 757's wing vorticii can flip a 737. You really get them when the plane is flying hot, heavy, and slow. They teach you how to avoid the problem by either landing in front of where the plane in front of you landed or waaaay behind it. Otherwise, you may find yourself up-side-down.</p> <p>Vorticii are powerful whether you are talking about water, air, or maybe even magma. I wouldn't be surprised if there are some very slow eddies in magma, but it is so thick and crystaline that it may not work as I don't think there are any vorticii in window glass. But you never know. What could be going on at the molecular level? I have seen the original glass double doors at Jefferson's home Monticello and you can see the waviness in the glass. BTW, you open one of the doors and the other one opens as they are driven by a figure 8 chain under the floor. Original chain, too. If you have never been to Monticello, do go if you can. It is a really neat place.</p> </div> <drupal-render-placeholder callback="comment.lazy_builders:renderLinks" arguments="0=2207897&amp;1=default&amp;2=en&amp;3=" token="PccZGtg05-hpzn48KHjbliOXcKu3nZ7mkezdOG3y2YQ"></drupal-render-placeholder> </div> <footer> <em>By <span lang="" typeof="schema:Person" property="schema:name" datatype="">Diane N CA (not verified)</span> on 02 Jul 2010 <a href="https://scienceblogs.com/taxonomy/term/27899/feed#comment-2207897">#permalink</a></em> <article typeof="schema:Person" about="/user/0"> <div class="field field--name-user-picture field--type-image field--label-hidden field--item"> <a href="/user/0" hreflang="und"><img src="/files/styles/thumbnail/public/default_images/icon-user.png?itok=yQw_eG_q" width="100" height="100" alt="User Image" typeof="foaf:Image" class="img-responsive" /> </a> </div> </article> </footer> </article> <article data-comment-user-id="0" id="comment-2207898" class="js-comment comment-wrapper clearfix"> <mark class="hidden" data-comment-timestamp="1278080023"></mark> <div class="well"> <strong></strong> <div class="field field--name-comment-body field--type-text-long field--label-hidden field--item"><p>Here's a Mulakot webcam time-lapse of yesterday's dust storm <a href="http://www.youtube.com/watch?v=RzOmr6u8k5E">http://www.youtube.com/watch?v=RzOmr6u8k5E</a><br /> You wouldn't want to be out in that!</p> </div> <drupal-render-placeholder callback="comment.lazy_builders:renderLinks" arguments="0=2207898&amp;1=default&amp;2=en&amp;3=" token="aD9F5NgaMkMEwwm5eUYhBFdpW4Ep2oqqVxrsROtoYew"></drupal-render-placeholder> </div> <footer> <em>By <span lang="" typeof="schema:Person" property="schema:name" datatype="">d9tRotterdam (not verified)</span> on 02 Jul 2010 <a href="https://scienceblogs.com/taxonomy/term/27899/feed#comment-2207898">#permalink</a></em> <article typeof="schema:Person" about="/user/0"> <div class="field field--name-user-picture field--type-image field--label-hidden field--item"> <a href="/user/0" hreflang="und"><img src="/files/styles/thumbnail/public/default_images/icon-user.png?itok=yQw_eG_q" width="100" height="100" alt="User Image" typeof="foaf:Image" class="img-responsive" /> </a> </div> </article> </footer> </article> <article data-comment-user-id="0" id="comment-2207899" class="js-comment comment-wrapper clearfix"> <mark class="hidden" data-comment-timestamp="1278081869"></mark> <div class="well"> <strong></strong> <div class="field field--name-comment-body field--type-text-long field--label-hidden field--item"><p>@dt9Rotterdam -

field--type-text-long field--label-hidden field--item"><p>@Diane:<br /> Yes, in a way I was thinking about windows flowing like in the Monticello (One of the places I must go to one of these days:). But I was more thinking in the way of a glass rod hanging suspended, the flow pattern is more exact there and you do not have to worry about the glass shattering.<br /> Here I do have to make many sad, the waviness seen in old glass is not glass-flow, it is due to the glass panes having been blown, not floated. Pilkingtons floated glass technic was not invented when Monticello was built.<br /> The way to see glass flow is to measure the top and bottom of old glass, if the top is thinner than the bottom, then you have glass-flow. The waviness and stuff in old glass will rather even out over time than oposite.</p> <p>Back to the vortex (eddy) thingamabit:)<br /> Yes as you say, we do not really have a clue about how the mantle is built up. We have secondary (tertiary really if you think about it) samples from it, but no real samples from the mantle since no one ever has drilled into it. As far as I know the only real tertiary sample is the drill core one from Kraflas magma-chamber. Otherwise only quartiary samples from the top of volcanos. The rest of it is only deduced theories not tested against reallity.<br /> With the risk of angering Erik here, the only thing we know is that there are gasses, and that the viscosity in the mantle can differ in between placces and that when it cools off (as magma) it can become rhyolitic mush (one sample). Otherwise it might only be nice theories, even though I agree with many of them and that the Krafla drill sample made many of the theories much more likely.<br /> But for all we know the actual mantle might consist of snowman dung for all we know. Science is a hard thing.</p> <p>Know with that off my chest, back to your question.<br /> Yes, gasses and different viscosities would affect a vortex heavilly since it chanes the rate of possible ascent upwards. Highly viscous gassy material would rise much faster and would probably be what tipped the balance and made the volcano go off. But this is speculation on my part since we do not know enough of the composition of the mantle.</p> <p>Tilt and rotation caused by earth revolvement.<br /> Yes, you are absolutely correct. A magmatic (Yes Ekoh, I know) vortex would revolve in the same direction as the toilett next to it when flushed.<br /> I am though not so sure of earths polar tilt affecting it though.<br /> Normal plumes are tilted due to tectonic plate movement (If I have understood things correctly), but here we do not have real tectonic movement. What! Am I Crazy? Here we have the mother of all tectonics!<br /> The tectonic movement at the MAR is pretty much the lowest on the planet, due to it being the origin of the american and eurasian plate movement. Yes it moves apart with 2,5cm a year on average, but those the MAR in itself move? I do not know. If the MAR in itself is moving, then we have a tilted plum, if not it might be untilted.<br /> The might be untilted comes from me not really being fully shure about if the MAR, the mantle, and the cores relative speeds. If all of them move in the same speed, Straight vortex. If the MAR is standstill and mantle moves, un-straight. And the most fun of them. Let's say that MAR and Core are same-speed and the Mantle is moving at another speed, then we have a strangely curved vortex that would loose some energy. And this was more idle speculation.</p> <p>Your airplane analogy is nice, the energy in a vortex can be tremendous, if there is a vortex like that between Grimsvötn and Askja then it is so powerrfull that it has lifted the entire Iceland and a large portion outside of it 50 metres from just the shear upwelling force of it. Really humbling if you think of it.</p> </div> <drupal-render-placeholder callback="comment.lazy_builders:renderLinks" arguments="0=2207912&amp;1=default&amp;2=en&amp;3=" token="wM3oeM3n1H4cmQHOMAQFwLSsz8PGpYlr315-RX4Jsvg"></drupal-render-placeholder> </div> <footer> <em>By <span lang="" typeof="schema:Person" property="schema:name" datatype="">Carl (not verified)</span> on 03 Jul 2010 <a href="https://scienceblogs.com/taxonomy/term/27899/feed#comment-2207912">#permalink</a></em> <article typeof="schema:Person" about="/user/0"> <div class="field field--name-user-picture field--type-image field--label-hidden field--item"> <a href="/user/0" hreflang="und"><img src="/files/styles/thumbnail/public/default_images/icon-user.png?itok=yQw_eG_q" width="100" height="100" alt="User Image" typeof="foaf:Image" class="img-responsive" /> </a> </div> </article> </footer> </article> <article data-comment-user-id="0" id="comment-2207913" class="js-comment comment-wrapper clearfix"> <mark class="hidden" data-comment-timestamp="1278141992"></mark> <div class="well"> <strong></strong> <div class="field field--name-comment-body field--type-text-long field--label-hidden field--item"><p>@#48 Hi Lurking,</p> <p>Your last comment,in brackets,sums things up perfectly.</p> </div> <drupal-render-placeholder callback="comment.lazy_builders:renderLinks" arguments="0=2207913&amp;1=default&amp;2=en&amp;3=" token="fFZRelJcUi1pl8CXUEC5h_xMN0MZquInWD2zzgkjYT4"></drupal-render-placeholder> </div> <footer> <em>By <span lang="" typeof="schema:Person" property="schema:name" datatype="">Adrian,Dorset, UK (not verified)</span> on 03 Jul 2010 <a href="https://scienceblogs.com/taxonomy/term/27899/feed#comment-2207913">#permalink</a></em> <article typeof="schema:Person" about="/user/0"> <div class="field field--name-user-picture field--type-image field--label-hidden field--item"> <a href="/user/0" hreflang="und"><img src="/files/styles/thumbnail/public/default_images/icon-user.png?itok=yQw_eG_q" width="100" height="100" alt="User Image" typeof="foaf:Image" class="img-responsive" /> </a> </div> </article> </footer> </article> <article data-comment-user-id="0" id="comment-2207914" class="js-comment comment-wrapper clearfix"> <mark class="hidden" data-comment-timestamp="1278143168"></mark> <div class="well"> <strong></strong> <div class="field field--name-comment-body field--type-text-long field--label-hidden field--item"><p>Lurking, what you are seeing in your plot is a cessation of the lowest level seismic signals.
