eklemetti | August 12, 2010Earlier this summer, we had a chance to ask Sally Kuhn Sennert of the Smithsonian Institution/USGS Global Volcanism Program questions about her job as the main writer of the well-loved Weekly Volcanic Activity Report. Well, now here are the answers!
Sally Kuhn Sennert of the Global Volcanism Program in front of Mt. Rainier, Washington.
Q&A Sally Kuhn Sennert:
Q: Could you describe how you go about putting together the weekly update?
A: If time permits, I would start to gather information on Friday when particular sources post their weekly summaries. The majority of the information…
eklemetti | July 29, 2010Lots of little pieces of news I've run across ... time to play a little catch up.
Stromboli: A volcano after Don Ho's heart.
Every once in a while, my RSS feeds will dredge up some articles from years gone by ... and this week there were two New York Times pieces that are a few years old, but interesting nevertheless. The first is about research conducted by Dr. Robert Sohn at WHOI on explosive undersea eruptions. The second is work by Corr and Vaughan about finding subglacial volcanism in Antarctica. Both are interesting reads if you missed them (like I did) the first time around.…

Kilauea lavas on the move near Kalapana. Image taken July 17, courtesy of the Hawaiian Volcano Observatory.
Some news over the last few days:
The lava flows from Kilauea are moving with a vengeance right now, damaging roads and heading for some structures. The lava flows near Kalapana have moved almost 200 meters since Sunday, closing within 100 yards of homes in the area. The lava is moving to the east along Highway 130 and 137 - and tourists are making it difficult to get around as they park to watch the lava - upwards of 2,000 people! A number of people (and dogs) have had to be…
eklemetti | July 8, 2010So, I'm a little late with this thanks to a little hiatus, but I thought I would post the latest GVP Weekly Volcanic Activity Report. Thanks again to the Smithsonian, USGS and especially Sally Kuhn Sennert!
Some highlights include:
There were more ash explosions spotted at Ebeko in Kamchatka, producing ~1.8 km (5,900 foot) ash columns. This activity prompted KVERT to raise the Alert Status to Yellow. This goes along with news from a pile of other Kamchatka/Kuril Island volcanoes: Gorely, Tiatia, Karymsky, Kliuchevskoi and Shiveluch.
More activity at Arenal in Costa Rica - its almost always…
eklemetti | July 1, 2010Just a reminder, if you any questions for Sally Kuhn Sennert of the Smithsonian/USGS Global Volcanism Program - about the Weekly Report, about life at the GVP, about volcanoes - be sure to send them to me soon at .
Now, on to this week's update!
Some highlights (not including Gorely):
Lahars from Tungurahua in Ecuador moved blocks upwards of 2 m in diameter downstream over the last week and ash fall was reported over 20 km from the volcano's vent. For some reason, FoxNews decided to use an image of Tungurahua for an article on stats of natural disasters in 2009 - nice image, but the volcano…
eklemetti | June 23, 2010The latest news from the world of volcanoes, brought to us by the Global Volcanism Program, USGS and the Smithsonian Institution. They are also brought to us by Sally Kuhn Sennert - and if you have a question for her about her job at the GVP preparing the Weekly Volcanic Activity Report and all things volcanic (and hopefully it won't end like another recent volcanically-mitigated interview).
Some highlights (not including Gorely and Sakurajima):
Ioto (aka Iwojima) in the Volcano Islands of Japan produced an ash plume of unknown height. The volcano has frequent phreatic eruptions and abundant…
eklemetti | June 22, 2010As a part of my continuing Q&A series, I am pleased to announce that Sally Kuhn Sennert, compiler and author of the weekly Global Volcanism Program Volcanic Activity Reports, is the next up to take your questions. A little bit about Sally:
Sally Kuhn Sennert graduated with a Bachelor's degree in Anthropology from the University of Pittsburgh in 1997. She worked with non-human primates for several years before deciding to switch gears and pursue her first love, Geology. She returned to the University of Pittsburgh, and completed her Master's degree in 2003 under the direction of Dr. Mike…
eklemetti | June 17, 2010Have guests in town, so I'm a little busy, but you can hopefully keep entertained with the latest Smithsonian/USGS Global Volcanism Program Volcanic Activity Report.
Chile's Melimoyu volcano.
The highlights (not including Taal and Eyjafjallajökull) include:
Alaska's Cleveland volcano has been reduced to and alert status of "unassigned" (used when a volcano is not closely monitored so AVO doesn't know what exactly is "background") after a few weeks of activity. The same was done for the submarine volcano south of Sarigan in the Marianas Islands after no signs of activity since the eruption…
eklemetti | June 9, 2010The latest update from the Smithsonian/USGS Global Volcanism Program!
Highlights (not including Taal, Eyjafjallajökull and Bezymianny) include:
Another thermal anomaly was spotted on an Kuril Island volcano - this one being Tiatia. The volcano has no seismic monitoring network, so the thermal anomaly is all that has been observed.
Lava flows and strombolian explosions continue at Guatemala's Pacaya. Some of the explosions have launched bombs hundreds of meters into the air.
Kliuchevskoi was another busy Russian volcano, with a large thermal anomaly and ash explosions that produced a plume…
eklemetti | June 3, 2010The level of news-frenzy on some of the recent volcanic eruptions has died down, but if you're looking to see information on the many rumbling going on worldwide, look no further. Here is this week's Volcanic Activity Report put together by Sally Kuhn Sennert of the Global Volcanism Program.
Highlights - not including Pacaya, Yasur, Tungurahua and our friend in Iceland - include:
The eruption in the Marianas apparently came from South Sarigan volcano - at least according to the best guess by folks who work in the Marianas. This submarine volcano apparently shows evidence of young lava flows…
eklemetti | May 28, 2010This week has been destroyed by workshops and my last death throes with a paper I am submitting on my research in New Zealand. And to think, I thought it might settle down a little after the students left.
To news!
Ash fall on a taxi cab near Guatemala's Pacaya.
Pacaya in Guatemala erupted yesterday causing evacuations of people near the volcano and the closure of Guatemala City's main airport. Pacaya is a mere ~25 km from the capitol of this Central American nation. Tragically, a news reporter from one of the capitol's TV stations died when they were struck by volcanic debris, again…
eklemetti | May 12, 2010Ah yes, a reminder that there are other volcanoes erupting around the world than Eyjafjallajökull - but yes, it is true! Here is the latest USGS/Smithsonian Global Volcanism Program Weekly Volcanic Activity Report!
Highlights (not including Iceland) include:
Another volcano in the Kuril Islands of Russia is showing signs of, well, something. Ketoi was noticed to be experiencing increased fumarolic activity according to satellite images. Ketoi hosts a Pleistocene caldera but has had three historic eruptions over the last few centuries, most recently in 1960, and all of which were explosive…
eklemetti | April 16, 2010Hard to believe, but there is other volcano-related news in the world ...
So, with all deference to Eyjafjallajokull, here it is:
Dome collapse on Colima in Mexico, image taken March 30, 2010.
The new Smithsonian/USGS GVP Weekly Volcano Activity Report was issued, with news about increasing signs of activity at Egon in Indonesia, a possible plume at Miyakejima in Japan and more dome growth at Soufriere Hills.
A study on the economic effect of a new Vesuvius eruption was released and the finding show the potential for a staggering $24 billion of economic damage directly related to an…
eklemetti | April 5, 2010Quick hits for a Monday morning (however, the week did have a good start).
Lava fountaining on March 27, 2010 at the Eyjafjallajokull-Fimmvörduháls eruption in Iceland.
The Eyjafjallajokull-Fimmvörduháls eruption is still going strong with two active fissure - and a lot of tourists poking around as well. If you watch the webcams closely, you can even see the cars and hikers trekking up near the erupting basaltic fissure (except today, as there seems to be a blizzard). Not to say that people are getting a little, well, nonchalant, but there is a story of serving meals cooked on lava up…
eklemetti | March 8, 2010Cleaning up some news ... busy week leading up to a field trip I am helping co-lead to Death Valley next week.
Ubehebe Crater in Death Valley, California
First off, I want to say how amazed I am at the great discussion that went on all weekend about the signs of potential activity in Iceland. It now appears that the earthquakes at Eyjafjallajökull may be waning, however the levels of seismicity have definitely bounced up and down over the last few days. However, the level and depth of the conversation is a testament to all volcanophiles out there. Nice job, folks.
For those of you into…
eklemetti | February 25, 2010The flu has retreated and I'm getting back on track. Huzzah!
I'll get back to the blog by posting this week's new USGS / Smithsonian Institution Global Volcanism Program Weekly Volcano Report. Looks like some interesting stuff in it ...
Looks like there were some small eruptions from Oldoinyo Lengai in Tanzania. The volcano is one of the few (only active?) carbonatite volcanoes in the world, erupting a lava composed primarily of calcium carbonate and sodium minerals with very little silica. It leads to the odd lava that erupt black (and cool ~ 500C) and cool to white, making it one of the…
eklemetti | February 19, 2010Long week, quick news:
Tiatia in Russia erupting in an undated photo.
The latest USGS/Smithsonian Institution

eklemetti | February 10, 2010Sally Sennert from the Smithsonian Institution sent me an email to say that this week's USGS/Smithsonian Institute Weekly Volcanic Report will be delayed due to the inclement weather in the Washington DC area. She can't connect with the server, so the report can't be updated on the Smithsonian website ... so here it is! Look for it to show up on the Smithsonian site with all the bells and whistles as soon as DC thaws out.
And a big thanks to Sally for sending me the Report to post.
***PLEASE NOTE: Website posting of the SI/USGS Weekly Volcanic Activity Report for 3-9 February 2010 will be…
eklemetti | February 4, 2010News!
Pakistan is home to the world's tallest mud volcano in the region of Balochistan - and its somewhat near the reports of an "eruption" earlier this week.
Guess what? Since Wednesday evening, seismicity at Yellowstone has dropped precipitously. The last batch of earthquakes on February 3rd were also back to deeper levels - 8-9 km depth - compared to the potential shallowing earlier in the week. I'm sure the caldera will keep us on our toes, but as of now, it seems to have settled down a bit.
Over in Pakistan, there is mounting evidence that the recent "volcanic" eruption reported as, in…
eklemetti | January 28, 2010Some news for the last Friday in January:
Volcanic lightning captured over Redoubt in March 2009.
Tungurahua in Ecuador continues to erupt. Yesterday, the volcano spread ash over much of central Ecuador. Apparently people in Ecuador aren't taking the hazard of ash too seriously, with many ignoring recommendations to wear masks when the ash is falling. Over 50 explosions have been recorded over the last 24 hours at the volcano according to the Ecuadorian Instituto GeofÃsico, most of them small to moderate.
We also have a new USGS/Smithsonian Institute Volcano Activity Report. Much of the "…
