Schools that were being used as evacuation centers were also returned to <a href="http://www.mb.com.ph/articles/236773/classes-resume-albay-monday" target="_blank">teachers and students for the start of classes</a> after the Christmas holiday. However, the Albay provincial government is now considering a plan to <a href="http://www.gmanews.tv/story/180751/permanent-relocation-of-mayons-6-km-zone-residents-eyed-gov" target="_blank">permanently move everyone</a> who lives within the 6-km danger zone around Mayon, even if the volcano no longer shows signs of eruption.</p> <p><strong>Nyamuragira</strong><br /> Over in the Congo, <a href="http://www1.voanews.com/english/news/africa/Congo-Volcano-Spews-Lava-80552772.html" target="_blank">Nyamuragira continues to erupt</a>. The <a href="http://www.un.org/apps/news/story.asp?NewsID=33396&amp;Cr=&amp;Cr1=" target="_blank">United Nations has been called in to help monitor</a> the situation from the air - mostly to make sure officials in the Congo know where the lava is going in the Virunga National Park and whether it might become a threat to the city of Goma. <a href="http://news.bbc.co.uk/2/hi/africa/8438203.stm" target="_blank">Some villages near the volcano</a> are now coming under threat from the lava flows, but thus far, no injuries have been reported. <a href="http://www.youtube.com/watch?v=UiXeone3R98" target="_blank">Kenyan TV has posted some great video of the rift eruption</a> that is producing tall fire fountains of the especially low viscosity (unlike what the video says) high-potassium basalts erupted from Nyamuragira. These high K lavas are so low in viscosity thanks to the potassium breaking the bonds in the silica network that makes up most magmas that erupt on Earth - so even though basalts are usually quite runny, the basalts from Nyamuragira are especially so - thus, the ability to flow tens of kilometers from the vent.</p> <p><strong>Galeras</strong><br /> Jumping across the Atlantic, Galeras has settled down after <a href="http://scienceblogs.com/eruptions/2010/01/galeras_has_large_eruption_-_1.php" target="_blank">its impressive explosive eruption</a> over the weekend. <a href="http://colombiareports.com/colombia-news/news/7516-authoritis-lower-level-of-alert-after-volcano-erupts.html" target="_blank">INGEOMINAS lowered the alert level at Galeras</a> on Sunday after signs of more explosions dissipated. However, considering how unexpected Saturday's eruption was, people should stay on alert for more activity. <a href="http://www.colombianews.tv/news/1310-galeras-volcano-erupts-near-pasto-narino" target="_blank">Some more video of the eruption</a> clearly shows lightning as well as the eruption plume during Saturday's big boom.</p> <p><strong>Redoubt</strong><br /> One more continent! Redoubt in Alaska seems to also be coming down from its late 2009 signs of life. Currently, <a href="http://www.avo.alaska.edu/activity/Redoubt.php" target="_blank">AVO</a> reports that <em>"seismic activity at Redoubt Volcano remains low"</em> and <a href="http://www.ktuu.com/Global/story.asp?S=11758329" target="_blank">only a faint steam plume</a> is visible when not obscured by clouds. Seems like Redoubt was just teasing us for attention.</p> <p><strong>Kilauea</strong><br /> Say, did you know that January is <a href="http://www.khon2.com/news/local/story/Volcano-Awareness-Month-Kicks-Off/l4MTHtdOj0qtWd_Moc38Vw.cspx" target="_blank">Volcano Awareness Month</a>?

It seems SO2 is the one measured most of the time. Is CO2 released along with the SO2? I thought it was as well as other gases. My DH and I think that a lot of the "global warming" talk takes what humans are releasing as the main "cause" when volcanoes, erupting or not, release far more than any of the industrial activity going on. Are there any reports of how much CO2 volcanoes are emitting? I know SO2 is one of the most dangerous because of the acid rain and other things it causes, but the CO2 shouldn't be ignored because there is a tree kill zone in Long Valley because of the CO2 coming out of the ground there. Then there is the Norris Basin in Yellowstone. So I am just wondering about the amounts of CO2 being released.</p> <p>Thanks for any info.</p> </div> <drupal-render-placeholder callback="comment.lazy_builders:renderLinks" arguments="0=2188708&amp;1=default&amp;2=en&amp;3=" token="prp0RQxsSZQRtSU1qRV74AIjCz3_VFRFuz41LYReIlo"></drupal-render-placeholder> </div> <footer> <em>By <span lang="" typeof="schema:Person" property="schema:name" datatype="">Diane (not verified)</span> on 05 Jan 2010 <a href="https://scienceblogs.com/taxonomy/term/28156/feed#comment-2188708">#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-2188709" class="js-comment comment-wrapper clearfix"> <mark class="hidden" data-comment-timestamp="1262710302"></mark> <div class="well"> <strong></strong> <div class="field field--name-comment-body field--type-text-long field--label-hidden field--item"><p>Any info that disproves something about global warming is ignoring by those who beleive in it and thrown under the rug.

Mayon is indeed a fascinating volcano..</p> <p>Usually, when a volcano erupts, the most violent phases are in the beginning. If we look at something like Mount Saint Helens or Chaitén, the most explosive "gassy stuff" was erupted first, then the activity stabilized into dome growth. Other, weaker eruptions like those from Hekla in Iceland, seem to show the same pattern, explosions first, then flowing lava.</p> <p>Mayon, in fact, seems to do exactly the opposite. Gas-poor lava is erupted first (remnants from previous eruption?) then gas contents increases and the eruptions ramp up progressively.</p> <p>Maybe this has to do with the plumbing system inside the volcano, perhaps an intermediate magma-chamber containing gas-poor material remaining from the last eruption. As this chamber fills up with hotter, gassier magma coming from the main chamber, the gas poor lava is first to be squeezed out, then gas-rich material reaches the surface and the eruption goes explosive. When the eruption is over, the contents of the middle chamber slowly degasses, ready for the cycle to be repeated.</p> <p>In the other type of eruptions, material from the main chamber may be piped straight to the surface, explodes then loses pressure, ending the eruption by quiet lava flows. </p> <p>All of this comes from pure speculation...

Mayon, which is very active and thus provides a record of numerous eruptions, is a very instructive example. In 1984, activity built up slowly - it started much the same way it's doing now - and then had its most intense phase after some two weeks. In 1993, it started with a devastating explosion and pyroclastic flow, leading to the nearly 80 deaths mentioned in David's note (11). Eruptions in 2000 and 2001 built up rapidly to strong explosive phases, whereas the latest eruption in 2006 remained relatively mild throughout (although more than 1000 people were killed in typhoon-generated lahars soon after the eruption).<br /> A correction is due for Mount St. Helens in 1980 - it did not go full scale explosive at the start, but after six weeks of relatively small phreatic explosions, seismic activity, and very pronounced swelling of its north flank. Indeed, Chaitén is one of the few examples of a major explosive eruption that went paroxysmal right from the start. Soufrière Hills on Montserrat, on the contrary, took about two years to reach its highest levels of activity (from July 1995 to June 1997). It's all a question of how much gas is in the magma, and in particular, how much water vapor and carbon dioxide: these are the gases that drive volcano explosive. Lack of such gas was also the reason why the latest eruption of Mount St. Helens (2004-2008) was largely non-explosive.<br /> In the case of Mayon, I believe that there we see something that we have often observed also at Etna: the conduit being essentially open all the time, each new uprise of more gas-rich magma first pushes out gas-poor magma remaining in the conduit, and that is why the onset of many Mayon eruptions is so gradual.</p> </div> <drupal-render-placeholder callback="comment.lazy_builders:renderLinks" arguments="0=2188447&amp;1=default&amp;2=en&amp;3="

Right now it is quiet again and most of the quakes are south of the caldera and are not much to get excited about.</p> <p>The Mammoth swarm had the USGS awake and there has been a swarm at Lassen also in an area just southwest of the mountain.

That quake was just out of West Yellowstone and was a 7+. I had been in the area with my family and we had just left Yellowstone before it happened. Yes, it was a major quake and it affected the geysers and Old Faithful has not been as faithful since. It is a bit harder to predict now, but they do a pretty good job of it. Also, I have been there a few years ago and there is another geyser in the area of Old Faithful that goes off at the same time. It was not doing that before. Also, Old Faithful doesn't go as high as it used to.</p> <p>I don't worry about Yellowstone at all. It is a beautiful place and had recovered very well from the fires of 1988.<br /> I am more concerned for SF than Yellowstone, but I am not worrying about it. I like to monitor what is happening because I like to see what is going on and I find it all facinating. I have felt a lot of quakes and they don't bother me much unless they do damage. There was one that woke me up at 5:30am once, I heard it, it moved up and down, and it put seven hairline cracks in the foundation of the house I was living in at the time. It was a 5+ south of Long Valley and it did some weird things. You could see how the side walk had shifted in a twisting motion and where the driveway came to the garage was offset. I had a rectangular bucket on the porch that shifted lengthwise to the direction the quake came from. We actually felt it more than those who were closest to the epicenter.</p> <p>Do I worry about quakes? No!</p> <p>I think we don't need to worry about something we have no control over and enjoy what we have and the beauty that is around us. If you live in the city, get out in the country once in a while.

At least for fairly low population areas evacuation can be effective. For a densely populated area like Napoli there is no doubt that the casualties will be very high if Vesuvius were to go whacky again. In the case of cities and earthquakes, Japan much more so than the US has buildings built to withstand quite severe shocks. Unfortunately, earthquakes give far less warning than volcanoes so at this point in time no one can claim to be able to evacuate before a major earthquake. Funny - a few months ago a friend of mine felt her first earthquake and was telling me about it "everything is shaking!". "It's just an earthquake" I said. "You seem awfully calm about it." she says.

The CO2 measurements are made partway up Mauna Loa at the meteorological observatory (MLO), site location 3397m amsl. I doubt the SO2 ever gets there in measurable amounts (and it is very easy to measure). Even if it did, it wouldn't affect the CO2 measurements at all. Come to think of it, you would need very unusual meteorological conditions at Hawaii to bring the SO2 up to the MLO. The OMI in orbit might be able to detect the extent of the SO2 plume on its daylight passes so you can use OMI images to see if any significant amount of SO2 arrives at the MLO - well, that is assuming that someone processes the OMI data for SO2 rather than ozone.</p> </div> <drupal-render-placeholder callback="comment.lazy_builders:renderLinks" arguments="0=2188291&amp;1=default&amp;2=en&amp;3=" token="qqgtgSPAlt6ZMLeh00p8MSMusdAG_TlQ5mGq5DqReO4"></drupal-render-placeholder> </div> <footer> <em>By <span lang="" typeof="schema:Person" property="schema:name" datatype="">MadScientist (not verified)</span> on 06 Dec 2009 <a href="https://scienceblogs.com/taxonomy/term/28156/feed#comment-2188291">#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-2188292" class="js-comment comment-wrapper clearfix"> <mark class="hidden" data-comment-timestamp="1260136029"></mark> <div class="well"> <strong></strong> <div class="field field--name-comment-body field--type-text-long field--label-hidden field--item"><p>@doug: Perhaps I should have written the *current* SO2 emissions.

After a few puffs last week, the volcano is now releasing a relatively constant stream of ash and steam, this after ~10 months of quiescence.

<p><em>Pohutu Geyser in Rotorua, New Zealand. Image taken by Erik Klemetti in January 2009.</em></p> <p>It has been busy busy week for me, capped off today with a talk about my field work in New Zealand (see above), so I don't have much to say. Not much new news today about the <a href="http://scienceblogs.com/eruptions/2009/05/harrat_lunayyir_and_the_saudi.php">Saudi Arabian earthquake swarms</a>, but again, I'll keep my eyes pealed (incidentally, I still haven't been able to figure out why no western news sources have even mentioned the swarm).</p> <p>Anyway, here's are some volcanic tidbits to enjoy over the long weekend:</p> <ul><li>Vog, as seen from space. Volcanic fog, fashionably shortened to "vog" is a real hazard in Hawai'i, <a href="http://scienceblogs.com/eruptions/2009/03/how_volcanoes_affect_the_econo.php">damaging crops and lungs</a>. The current shuttle mission (to repair Hubble), landing tomorrow, took some great images of Hawai'i, showing not only the <a href="http://earthobservatory.nasa.gov/NaturalHazards/view.php?id=38709">vog on the island</a>, but also the <a href="http://earthobservatory.nasa.gov/NaturalHazards/view.php?id=38734">ocean entry of lavas from Kilauea</a>.</li> <li>In the bevy of <a href="http://scienceblogs.com/eruptions/2009/05/29th_anniversary_of_the_mount.php">Mt. Saint Helens anniversary</a> articles this week, there were a couple that mentioned the new monitoring equipment being installed on the volcano. They are relatively inexpensive <a href="http://www.thenewstribune.com/news/local/story/746585.html">GPS units called "spiders"</a>. They do have a bit of Skynet in them as the spiders will have "<em>computer-programmed "brains" can decide what some data means and which information is most important</em>". However, they do seem to be about as state-of-the-art of any volcano monitoring I've ever seen. <em>{Hat tip to Eruptions reader Richard Gardner for this news.}</em></li> <li>The <a href="http://www.ktuu.com/Global/story.asp?S=10392867">economic impact of the current activity at Redoubt</a> is beginning to be felt in Alaska. The state figures it might be losing $1.5 million per month for the shutdown of Cook Inlet production due to the threat to the <a href="http://scienceblogs.com/eruptions/2009/04/oil_from_the_drift_river_termi.php">Drift River Oil Terminal</a>. Meanwhile, AVO continues <a href="http://www.peninsulaclarion.com/stories/051909/new_294210370.shtml">to wait for the big dome collapse</a> that is likely to occur at the Alaskan volcano.</li> </ul></div> <span><a title="View user profile." href="/author/eklemetti" lang="" about="/author/eklemetti" typeof="schema:Person" property="schema:name" datatype="">eklemetti</a></span> <span>Fri, 05/22/2009 - 08:17</span> <div class="field field--name-field-blog-tags field--type-entity-reference field--label-inline"> <div class="field--label">Tags</div> <div class="field--items"> <div class="field--item"><a href="/tag/alaska" hreflang="en">Alaska</a></div> <div class="field--item"><a href="/tag/cascades" hreflang="en">cascades</a></div> <div class="field--item"><a href="/tag/harrat-lunayyir" hreflang="en">Harrat Lunayyir</a></div> <div class="field--item"><a href="/tag/hawaii-0" hreflang="en">Hawai&#039;i</a></div> <div class="field--item"><a href="/tag/kilauea" hreflang="en">Kilauea</a></div> <div class="field--item"><a href="/tag/new-zealand" hreflang="en">New Zealand</a></div> <div class="field--item"><a href="/tag/redoubt" hreflang="en">Redoubt</a></div> <div class="field--item"><a href="/tag/remote-sensing" hreflang="en">remote sensing</a></div> <div class="field--item"><a href="/tag/saint-helens" hreflang="en">Saint Helens</a></div> <div class="field--item"><a href="/tag/satellite-images" hreflang="en">Satellite images</a></div> <div class="field--item"><a href="/tag/saudi-arabia" hreflang="en">Saudi Arabia</a></div> <div class="field--item"><a href="/tag/united-states" hreflang="en">united states</a></div> <div class="field--item"><a href="/tag/vog" hreflang="en">Vog</a></div> <div class="field--item"><a href="/tag/volcanic-gases" hreflang="en">volcanic gases</a></div> <div class="field--item"><a href="/tag/volcanic-hazards" hreflang="en">volcanic hazards</a></div> <div class="field--item"><a href="/tag/volcano-hazards-program" hreflang="en">Volcano Hazards Program</a></div> <div class="field--item"><a href="/tag/volcano-monitoring" hreflang="en">volcano monitoring</a></div> <div class="field--item"><a href="/tag/volcanoes-and-economy" hreflang="en">volcanoes and the economy</a></div> <div class="field--item"><a href="/tag/st-helens" hreflang="en">St. Helens</a></div> <div class="field--item"><a href="/tag/remote-sensing" hreflang="en">remote sensing</a></div> <div class="field--item"><a href="/tag/volcanic-gases" hreflang="en">volcanic gases</a></div> <div class="field--item"><a href="/tag/volcanic-hazards" hreflang="en">volcanic hazards</a></div> <div class="field--item"><a href="/tag/volcano-monitoring" hreflang="en">volcano monitoring</a></div> <div class="field--item"><a href="/tag/volcanoes-and-economy" hreflang="en">volcanoes and the economy</a></div> </div> </div> <section> <article data-comment-user-id="0" id="comment-2186781" class="js-comment comment-wrapper clearfix"> <mark class="hidden" data-comment-timestamp="1243001965"></mark> <div class="well"> <strong></strong> <div class="field field--name-comment-body field--type-text-long field--label-hidden field--item"><p>Not quite right that no Western media have picked up on the quakes;

Taken from March 28, 2009, 50 miles from Redoubt.</em></p> <p>Redoubt continues to huff and puff, with an almost constant ash plume of ~15,000 feet / 5,000 meters. This after ~4 PM (Alaska Time), an explosion produced a 25,000 foot / 8,000 meter ash column that <a href="http://www.fortmilltimes.com/124/story/513101.html" target="_blank">disrupted flights</a> in and out of Anchorage again. Also, the air in the Kenai Peninsula area is beginning to feel the effects of the eruption, as AVO notes:</p> <blockquote><p><em>Satellite images from this morning show a broad layer of volcanic haze extending east of the volcano over the Kenai Peninsula, the Anchorage Bowl, and the Matanuska-Susitna Valley.</em></p></blockquote> <p>You can see what ash does to the air in some of <a href="http://www.avo.alaska.edu/image.php?id=17536" target="_blank">the images</a> posted on the Redoubt AVO page, along with some pictures from the <a href="http://volcanoes.usgs.gov/avo/dbimages/display/thumb/1238470906_ak231.jpg" target="_blank">overflight of the volcano</a>. Calvin Hall has provided me with some of his own pictures, including a spectacular shot of lightning being generated in the clouds of the Redoubt ash column (above). Calvin also reports "The vog today was miserable. Finally had clear weather, then could not see thru the vog."</p> <p>Other great tease from the <a href="http://www.avo.alaska.edu/activity/report_getter.php?need=current&amp;id=3940&amp;type=2" target="_blank">AVO update</a> this afternoon is this gem:</p> <p><em><br /><blockquote>Satellite images from last night show a thermal anomaly at the vent and are possibly due to the extrusion of a lava dome in the summit crater.</blockquote></em></p> <p><br /> Yup, we might be starting to see new magma at the surface, in other words, the new dome. I'm sure if conditions permit, the AVO field crew will try to get a glimpse of this in their observation flights.</p> <p>And for those of you, like me, who love the crystals in magma, AVO has posted some backscatter electron microprobe images of minerals from the currently eruption, including a <a href="http://www.avo.alaska.edu/image.php?id=17484" target="_blank">pretty knackered amphibole</a> showing reaction rims (disequilibrium), some nicer looking <a href="http://www.avo.alaska.edu/image.php?id=17487" target="_blank">calcic pyroxene</a>, <a href="http://www.avo.alaska.edu/image.php?id=17488" target="_blank">orthopyroxene</a> rimmed with plagioclase and a gorgeous, <a href="http://www.avo.alaska.edu/image.php?id=17492" target="_blank">zoned plagioclase</a>.

However, in Hawai'i, <a href="http://www.msnbc.msn.com/id/29595775/" target="_blank">a new effect of volcanism has been seen in the agriculture of the state</a>. The <a href="http://hvo.wr.usgs.gov/volcanowatch/1996/96_05_29.html" target="_blank">volcanic fog - or "vog"</a> as its called - has been causing major problems with farms on the Big Island of Hawai'i. Since the new activity at Halemaumau (see above) began last year, Kilaeua has been spewing much larger volumes (2-4 times more) of volcanic gases such as sulfur dioxide, carbon dioxide, water and carbon monoxide than in previous years. These gases form a brown fog that is caustic to most animals and plants. The sulfur dioxide, in particular, has caused many crops to fail thanks to the production of <a href="http://hawaiigardening.blogspot.com/2008/03/volcanic-acid-rain.html" target="_blank">sulfuric acid with the sulfur dioxide interacts with water </a>- think of it as a very concentrated version of <a href="http://en.wikipedia.org/wiki/Acid_rain" target="_blank">"acid rain"</a> that is seen in the eastern United States.</p> <p>The solution to this would either be to build "vog-proof" air-filtering greenhouses or planting a limited set of plants that seem to withstand the effects of the vog. Alternately, one can hope that the gas emissions from Kilaeau will return to lower levels, allowing for the plants to survive. In any of these cases, the growers on the island face a large financial hardship in order to keep their businesses alive in the face of the volcano. This passive destruction of plants by Kilaeua shows how even when a volcano seems to be benign, it can inflict millions of dollars of damage on the local economy.</p> </div> <span><a title="View user profile." href="/author/eklemetti" lang="" about="/author/eklemetti" typeof="schema:Person" property="schema:name" datatype="">eklemetti</a></span> <span>Wed, 03/11/2009 - 12:29</span> <div class="field field--name-field-blog-tags field--type-entity-reference field--label-inline"> <div class="field--label">Tags</div> <div class="field--items"> <div class="field--item"><a href="/tag/basaltic-eruption" hreflang="en">basaltic eruption</a></div> <div class="field--item"><a href="/tag/effusive-eruption" hreflang="en">effusive eruption</a></div> <div class="field--item"><a href="/tag/hawaii-0" hreflang="en">Hawai&#039;i</a></div> <div class="field--item"><a href="/tag/kilauea" hreflang="en">Kilauea</a></div> <div class="field--item"><a href="/tag/mitigation" hreflang="en">mitigation</a></div> <div class="field--item"><a href="/tag/sulfur-dioxide" hreflang="en">sulfur dioxide</a></div> <div class="field--item"><a href="/tag/united-states" hreflang="en">united states</a></div> <div class="field--item"><a href="/tag/vog" hreflang="en">Vog</a></div> <div class="field--item"><a href="/tag/volcanic-gases" hreflang="en">volcanic gases</a></div> </div> </div> <section> <article data-comment-user-id="0" id="comment-2185826" class="js-comment comment-wrapper clearfix"> <mark class="hidden" data-comment-timestamp="1291422562"></mark> <div class="well"> <strong></strong> <div class="field field--name-comment-body field--type-text-long field--label-hidden field--item"><p>Hi, keep up the good work!</p> </div> <drupal-render-placeholder callback="comment.lazy_builders:renderLinks" arguments="0=2185826&amp;1=default&amp;2=en&amp;3=" token="9-080gZVU9xI1-TEj_8y9tHaso5ZK62SbsenAx7vTEw"></drupal-render-placeholder> </div> <footer> <em>By <a rel="nofollow" href="http://druidstorekoreaonline.com" lang="" typeof="schema:Person" property="schema:name" datatype="">Ronald Lene (not verified)</a> on 03 Dec 2010 <a href="https://scienceblogs.com/taxonomy/term/28156/feed#comment-2185826">#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-2185827" class="js-comment comment-wrapper clearfix"> <mark class="hidden" data-comment-timestamp="1291903820"></mark> <div class="well"> <strong></strong> <div class="field field--name-comment-body field--type-text-long field--label-hidden field--item"><p>The closing paragraph tells all of it in my opinion.

The flow itself is headed towards what is called the "Waikupanaha ocean entry" on the southeast side of the island. The lava flow has about one mile to go before it reaches the Pacific Ocean, but it has travelled several hundred feet (maybe 100 meters) over the last 10 days according to Park Rangers and USGS geologists monitoring the flow's progress.</p> <p>Of course, compared to your average pyroclastic flow or lahar, traveling at tens to hundreds kilometers per hour, tracking this lava flow is a little bit like watching paint dry (except, of course, it is lava). It shows the whole different level of volcanic hazard presented by Hawaiian volcanism versus Plinian (explosive) volcanism, where the level of concern at the park can be summed up with "<em>O</em><em>u</em><em>r idea is not to control and prevent.

The current report on the volcano tells of <a href="http://www.foxnews.com/story/0,2933,377701,00.html" target="_blank">a new fire fountain</a> at the Thanksgiving Eve Break-out "rootless cone", about 6 miles from the ocean. The fire fountain started on Sunday night, issuing lava up to 40 feet in the air and the <a href="http://hvo.wr.usgs.gov/kilauea/update/archive/2008/Jun/July72008fountain3.mov" target="_blank">USGS has posted an amazing video of the fountaining</a> on the <a href="http://hvo.wr.usgs.gov/" target="_blank">HVO website</a>. However, unlike the predicted behavior where magma at Kilauea starts near the summit and moves into the rifts, these lavas appear to be unrelated to the activity going on at the summit of Kilauea. This could mean that we have less of a grasp on the internal plumbing of this giants shield volcano than we previously thought ... and it is always exciting when nature decides to prove us wrong! </p> <p>This heightened state of eruption at Kilauea during the past week has also <a href="http://www.upi.com/Science_News/2008/07/08/Kilauea_lava_eruption_continues_in_Hawaii/UPI-41211215535948/" target="_blank">doubled the levels of sulfur dioxide</a> being emitted from the volcano, which, of course, leads to more of the dreaded vog.
