Tourists hiking next to an active lava flow on Pacaya in Guatemala in 2006.
I'm flying back to Ohio today after a successful few weeks of fieldwork/paper writing. Apparently I have a pile of tomatoes waiting in our garden in Granville ... !
On to news:
To go with the news that lava flows from…

One of the commemorate Eyjafjallajökull ash stamps being issued by the Icelandic Post - made with ash from the eruption itself.
Many Eruptions readers would consider themselves volcanophiles (or volcanificiandos?) and I would venture to guess there is a subset of volcano enthusiasts who are also…

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…

OK, 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…

I'm officially out of the mountains in the Mineral King area - the field work went great, we collected some fabulous Triassic-Jurassic rhyolites from a pendant in the Sierra Nevada Batholith (and also enjoyed blueberry-sized hail and an unfortunate hike through a thorny thicket). I'll have more to…

Our tour of the Marianas begins SW of Guam. In this area the volcanoes are submerged and make up a region known as the Southern Seamount Province. Our first stop is Tracey Seamount, which lies 30 km west of Guam. Tracey is a ~2 km tall cone and volume of ~45 km3 It is one of the smaller volcanoes…

MVP 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…

This week I welcome Dr. Ed Kohut as a guest blogger here on Eruptions (while I am off in the Sierras doing some field work). I've known Ed for 10 years now - we were both graduate students in igneous petrology at Oregon State University - and we are both Massachusetts natives. Ed was in the Coast…

The latest Eruptions Word of the Day is "Tuya".
So, what is a tuya?
This is a tuya:
A tuya! Click on the image to see a larger version. Image by Erik Klemetti.
Alright, well, that doesn't entirely help, does it?
Lets look at the feature the arrow indicates. Some observations:
(1) It is low and…

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.

Mineral King valley in California.
Well, we are in the peak of the summer, so Eruptions will be running a bit of summer schedule while I'm off away from the interweb tubes. First off, from July 11-20, I'll be off in the mountains, doing some much-needed fieldwork with my (first) undergraduate…

Quick hits to wrap up the week:

Following up some news about Changbaishan/Changbai caldera in North Korea, Yang Qingfu, director of earthquake and volcano analysis and forecast center with the seismology bureau of…

So, 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,…

Thanks for all the words/advice about Pepsigeddon here at SB. If you missed it, the powers that be have officially pulled the plug on the PepsiBlog. However, this crisis (as much as blogging can be a crisis) has reinforced a lot of long-standing problems with the management here at SB, so not to…

This hiatus for Eruptions lead me to do one thing I said I would never do ... but strange times call for strange measures. Eruptions has opened up a Twitter account (and I feel a little dirty about it), so if you want to follow the sporadic posts that might show up there, you can follow the blog…

If 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…

A few very quick hits:
Ever-looming Mt. Rainier, with Tacoma, Washington in the foreground.
PHIVOLCS is pondering whether to lower the Alert Status at Taal back to Level 1. The volcano has been on Alert Level 2 for the past month after increasing signs of potential eruptive activity. However,…

We'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…

Serpentine (as known as serpentinite), the current (and potentially soon-to-be ex-) state rock of California.
This does not have a direct connection to volcanoes, but it sure is about geology and the science in the news. State Senator Gloria Romero of California has sponsored a bill to change the…

So, I've had requests on the blog to help to do some defining of volcanologic terms on the blog, so I thought I'd try a new column called Eruptions Word of the Day. I'm not sure how often it will run, but let's give it a try.
Eruptions Word of the Day for July 5, 2010: Dacite
Dacite is a magma type…

Maybe 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…

Just 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…

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…
June 28, 2010
After 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'…

News!
The summit crater lake at Gorely in Russia, taken on June 21, 2010. Image courtesy of KVERT.
Eruptions readers have been abuzz about how KVERT will be closing shop (yet again) at the end of June. This would, of course, leave no local monitoring and expertise in the very active Kamchatka…
June 25, 2010
It 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…
June 23, 2010
The 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…
June 22, 2010
As 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…

Sakurajima in Japan erupting in 2000.
Sometimes, it is the volcanoes that erupt out of the blue that get all the attention, leaving the ones that are constant producers to be ignored by the fawning media. Sakurajima in Japan is just one of those constant erupting volcanoes that doesn't get its just…

Africa is threatened by "scorching hot blobs of magma" according to the CSM.
Nothing like some fabulous headlines to make your day.

Oh my! Yes, again, it seems that the many people…
