class participation
eklemetti | August 22, 2010As I've mentioned, I will be giving a talk here at Denison on the Eyjafjallajökull eruption and how the events unfolded on the internet - specifically, I'm interested in the idea of the general public taking an active role in volcano monitoring. So, I have a request from Eruptions readers - and by no means do you have to take part. However, if you are willing, I'd like to know your professional/"day job" and your geologic background - be sure, I will not use your real name or connect your Eruptions pseudonym to any information you send. I am just looking to get a hold on the backgrounds of…

Alaska's Augustine erupting.
Big volcano news while I'm off in the woods? Post it here!
eklemetti | August 10, 2010
Well, the summer is rapidly coming to an end - classes start here at Denison on August 30. So, we are trying to squeeze what we can out of the season and to that end, I'll be on one of these things called "vacations" for the next couple weeks. (Oh yeah, and I will be going through Yellowstone, so I'll personally check on those earthquakes, OK?)
That means Eruptions will be operating on the second summer schedule. No new posts until August 23, but some upcoming (automatically posted) articles including the answers to your questions for Sally Kuhn Sennert of the Global Volcanism Program and…
eklemetti | August 9, 2010Quiet weekend on the whole, volcano-wise, beyond the articles about the latest eruption at Karangetang. So, we'll start this week with a new Mystery Volcano Photo. The last MVP was Tarawera in a shot I took from a road on the back side of the volcano, so that leaves the current standings looking like this:

Eyjafjallajökull erupting in the spring of 2010.
I have a request for all of you Eruptions readers! In a few weeks I will be giving a talk here at Denison on the Eyjafjallajökull eruption and especially the aspects of how the eruption unfolded on the web. I think the shared experience of the seismicity, fissure vent eruption and explosive eruption - along with all the ramifications of the air traffic stoppage over Europe - was a fascinating phenomenon. So, I ask you readers: How would you describe your experience on Eruptions during the Eyjafjallajökull events? By that I mean in terms of…
eklemetti | July 26, 2010When we last left MVP, the latest entry actually did give people some trouble - but Don Crain ended up landing the winner at guess #15. The volcano is Ollagüe along the Chilean/Bolivian border. I took this shot from the road that comes up from the south towards Ollagüe (the town). Now, I have been to Ollagüe (the town) in almost 10 years now, but I did stay in a "hotel" called the Hotel Brin Bran - good soup, surly owner, nice view of both Ollagüe (the volcano) and Aucanquilcha. Definitely the vacation spot if you're visiting the high Andean Chilean/Bolivian frontier.
So, our standings:…
eklemetti | July 20, 2010OK, first off an apology for this week: I will be kind of crazy busy while in Davis - two papers to churn through so we can get them submitted sometime this summer, so blogging may be minimal. So, remember, whenever you hear people talk about how professors have it easy because they get the summer "off" ...
Second off, another apology: Dr. Ed Kohut went to Boston College, not Boston University. You would have thought I could keep that straight, but alas, I confuse my Eagles with my Terriers.
Mea culpa to all!
Anyway, I have to send out a hearty congratulations to Boris Behncke destroying my…
eklemetti | July 14, 2010MVP 23 revealed ... and 24 introduced!
Mystery Volcano Photo #23 was, in fact, Middle Sister volcano in Oregon, part of the picturesque Three Sisters near Bend. Middle Sister is a partially eroded (by glaciers) composite volcano with a mix basaltic andesite to andesite lava flows and tephra deposits. Depending on who you speak with, Middle Sister gets lumped in with North Sister (as Middle Sister build up on the flanks of its slightly older sibling) or stands on its own as a part of the Three Sisters. However, before thinking Middle Sister is dormant, remember, the last eruption might have…

New eruption? New volcano research announced? New media attention put on all things volcanic? Post it here and feel free to discuss ...
I'll be back July 20.
eklemetti | July 7, 2010If you haven't heard, ScienceBlogs HQ has put its foot squarely in its jaw thanks to a little poor decision-making. Now, Eruptions is a little outside the mainstream of ScienceBlogs - there aren't many corporations that might influence my posting (unless you suddenly see "Eruptions - brought to you by RyanAir" the next time an Icelandic volcano erupts), so I would hope that the credibility of this blog is hopefully not too threatening by the PepsiBlog, but I feel for my other ScienceBloggers who may be adversely effected for various reasons. In solidarity with them, Eruptions will be quiet…
eklemetti | July 6, 2010We'll try again with a finding a good Mystery Volcano Photo!
The last MVP was Mt. Meru in Tanzania, submitted by Michael Dalton-Smith. Now, I thought this image was going to be a little harder than it turned out to be as the shot of Meru on Wikipedia is a very similar shot, but that happens sometimes - and it did take 9 guesses this time! Congrats to MK in Alberta for getting that MVP. As for Meru, the last known eruption from this African volcano was in 1910, a VEI 2 explosive event from the aptly named "Ash Cone". Meru appears to have been relatively active during the late 1800's and early…
eklemetti | July 2, 2010Maybe I should be pleased that in the last Mystery Volcano Photo took a whole five guesses rather than one or two, so I count it as success! The correct guess was made by Dr. Boris Behncke, so that elevates him into a tie for first.
Current Standings:
The Bobs - 3
Don Crain - 3
Boris Behncke - 3
gijs - 2
volcanista - 1

Elizabeth - 1

The 21st MVP was submitted by Eruptions reader David Tucker, who snapped it while flying over the Kamchatka Peninsula on his way to Japan. The volcano in…

An explosion at the Santiaguito dome at Santa Maria in Guatemala.
Now, we've been talking recently about funding volcano monitoring - specifically with the threat that KVERT in Russia will close down after today (June 30). Well, Jessica Ball over at Magma Cum Laude has another worthy volcano observatory that needs your help. The Santiaguito Volcano Observatory, run by the INSIVUMEH in Guatemala, is the main station to watch over the activity at Santa Maria and the (very) active Santiaguito domes near the Pacific coast of the country. However, this observatory is run an a shoestring budget if…
eklemetti | June 28, 2010After last week's attempt to revive Mystery Volcano Photo - and the discovery (by me, thanks to you readers) of Tin Eye - I've had to ponder how to continue. Well, I think the best thing to do is to try using reader images that hopefully aren't hiding out on the web somewhere. So, that is what we'll try ...
As for MVP #20, the answer was, indeed, Edziza in Canada (congrats to Stephen). Edziza is an eroded composite stratovolcano that last erupted ~950 AD (+/- 1,000 years ... !) The volcano has erupted basalts to more felsic magmas, many of which were subglacial eruptions.
The current…
eklemetti | June 25, 2010It has been a quiet week, volcanically-speaking that is. Maybe they're all watching the World Cup, but there hasn't been a lot of new and exciting news to report this week. So, I thought this might be a good time to bring back Mystery Volcano Photo! Now, for those of you just joining us, I post a volcano photo and you have to identify it. The first person to get it right scores a point. We haven't done an MVP in a while (mostly because you all are too good at it), so to refresh our memories, the current standings:
The Bobs - 3
Don Crain - 3
gijs - 2
Boris Behncke - 2

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 10, 2010On advice of Eruptions reader Ekoh, I thought it would be fun to try to come up with a list of the most tongue-twisting and bizarre volcano names out there. I know there are a few out there that I've only typed once (the rest of the time I cut-and-paste), so lets review some recent fun ones:
Eyjafjallajökull (Iceland) - everyone's favorite tongue twister.
Eyjafjallajökull erupting in mid-May, 2010.
And people are still talking about the how the ash crisis was handled.
Kliuchevskoi (Russia) - It doesn't help that it has like ten names to boot (from the Smithsonian GVP):
KAMCHATSKAIA GORA…
eklemetti | May 14, 2010Time to play a little catch up ...
Eyjafjallajökull erupting in early May. Image by and courtesy of Martin Rietze.
A brief update on our friend Eyjafjallajökull - the eruption plume from the volcano was considerably taller yesterday, reaching 6-9 km (20,000-30,000 feet), but prevailing winds meant the ash hazard was confined to areas in the middle of the North Atlantic and northern parts of the British Isles. However, even as the ash hazard for Europe wanes (for now), you shouldn't forget the amount of ash being dumped on parts of Iceland. If you want to see some stunning images of the…

Mount St. Helens erupting in 1980.
Just a reminder ... please send them to me by May 15 so I can get them all ready for the post on the 18th!
As many of you might (or might not) now, we're heading towards the 30th anniversary of the dramatic eruption of Mount St. Helens in Washington state. Now, I could fill a book with the information out there on the volcano and the eruption, but instead, I think it would be more interesting to get your takes on the eruption. I have to admit, I was all of three when the eruption occurred, so my memories of the event are hazy at best, but if you have any…
