The first Q&A with Dr. Jonathan Castro was such a success, I'm going to try to make this a regular feature. On that note, Eruptions reader Dr. Boris Behncke has volunteered to be the second geologist to take the plunge. Here is a little about Boris and his work:
I've studied geology first in…

The SI/USGS GVP site is back up and running - and they've posted a new weekly volcano activity report. Enjoy!
Highlights include:
Nevado del Huila in Colombia has been showing signs that a new eruption might be starting. Seismicity has increased and minor ash fall has been reported, leading to an…

I'll be giving a talk this afternoon here at Denison on rhyolite generation, so I might be a little brief this morning.

The province of Albay in the Philippines is on alert for both a typhoon and a volcano (that country seems to be hit with that 300,000…

A few weeks ago I asked you to submit questions on the 2008-present Chaiten eruption in Chile to pose to Dr. Jonathan Castro. Dr. Castro recently had a paper on the ascent rates of Chaiten rhyolite published in Nature and he kindly volunteered to answer your questions. Here are the answers to…

The southern Washington (and northern Oregon) Cascades, with Hood (foreground), St. Helens and Adams (middle) and Rainier (background).
Remember a few months ago when an abstract from a meeting got people are ruffled because the study said there was a "giant magma chamber" feeding all three of St.…

I finally remembered to bring my GSA notes with me to the office, so I can finally post a wrap up of what I saw/heard at the big 2009 meeting in Portland. I'll have a specific post on Kasatochi - too much to say here. However, a great time was had by all!
The crater of Collier Cone in Oregon. The…

I did an excellent job of forgetting my notes from GSA 2009, so no wrap up on the meeting until tomorrow, but we do have some new volcano news to digest:
The crater of El Reventador in Ecuador in an undated photo.
Ecuadorian officials have called for evacuations around El Reventador. The Ecuadorian…

I did a really terrible job of updating during the Geological Society of America meeting - mostly because (a) I was way too busy, (b) an iffy internet connection at my home and (c) a lack of concentration.
However, there was quite a bit of interesting info I heard which I'll likely post tomorrow…

I will be returning to my old haunts in Oregon (got my Ph.D. from Oregon State University - and yes, that is me in the upper left hand corner) for the next 6 days for the the Cascades, CVO and the multitude of igneous-rock-…

A 1995 photo of Gaua volcano in Vanuatu.
A few weeks ago I mentioned that there were signs that Mt. Garet, part of the larger Gaua volcano in Vanuatu was potentially showing signs of a eruption - the first since 1982. It turns out that the rumbling and sulfur odors reported by local residents were…

Before we get to the latest SI/USGS Weekly Volcanic Activity Report (WVAR), I wanted to draw your attention to some nifty NASA Earth Observatory images from the current activity at Soufriere Hills in Montserrat. After a few puffs last week, the volcano is now releasing a relatively constant stream…

Happy Earth Science Week!
Mt. Baker in Washington, USA.
The Mount Baker Volcano Research Center (MBVCC) run out of Western Washington University has posted a series of new pictures and movies of the summit region of Mt. Baker (taken from 2006 to 2009). They also sent out links to some great images…

Busy Monday with Dr. Steven Squyres, the Principle Investigator of the Mars Exploration Rover Mission (MER; otherwise known as the plucky Spirit and Opportunity) is at Denison to give a talk and meet with students.
On that note, here is Mystery Volcano Photo #9.
And if you have any more questions…
October 9, 2009
Somehow I missed a week of the SI/USGS Weekly Volcano Activity Reports and almost missed another. Here is this week's update!
Highlights (not including Chaiten, Soufriere Hills or Cleveland) include:
The alert level at Galeras in Colombia was raised to Red after an explosion on September 30 and…

I mentioned this at the end of the post on recent Nature paper by Castro and Dindwell on the speed of rhyolite magma ascent at Chaiten, but I'll break it out to get your attention:
>Do you have a burning question about the Chaiten magma you'd love to be able to ask Dr. Castro? He has kindly…

Chaiten has made it back into the news in the past couple days, both with new events at the caldera and with findings from the initial blast in May 2008. Here goes:
Chaiten erupting in 2008.

The latest USGS/SI Weekly Volcanic Activity Report mentions that over the last week,…

Sometimes it is hard to keep up with the mountain of remote sensing (or not so remote) images that get released on the internet. Over the last few days, the NASA Earth Observatory has released a bunch of images/videos of current eruptions, so I thought I'd round them all up here for you to peruse…

Two volcanoes that have been rumbling and rocking for a while now made some noise today:
Kliuchevskoi Volcano in Russia.
Soufriere Hills on Montserrat had a relatively impressive explosive event, producing a ~3 km / ~11,000 foot ash plume - its first eruption in 10 months. This was after a sharp…

The last MVP was decidely (and unintentionally) way too easy ... but congratulations to gg for getting it on the first guess. To make up for that "gimme", here is a bit more of a puzzler.

And not because the Indians' season is finally (mercifully) over (zing!)
Cleveland steaming away in a 2008 AVO image.
Cleveland (the volcano) erupted on Friday, producing an ash column that reached 4.5-6 km / 15,000-20,000 feet. The full report from AVO:
Satellite data indicate that Cleveland…

News to finish up your week:
Summit area of Hualalai in Hawai'i
Another day, another "threat" of volcanic eruption in Australia. I'm impressed with the abject fear Aussies seem to have for this perceived increased threat of an eruption - or at least what the press wants you to believe. This time,…

Gaua volcano in Vanuatu.
Gaua volcano in Vanuatu is showing signs that it could be headed towards an eruption. News reports from the island nation in the south Pacific Ocean mention "increased seismic activity, generating sulphurous gas and ash into the atmosphere and affecting water supplies."…

It is a tight race!
Here's MVP #6 ... give it your best shot.
October 1, 2009
I've never been very good about asking for donations for anything, mostly because I know that for many of us, money can be tight. However, when it comes down to it, there are almost always people less fortunate than those of us who can spend our time blogging - or reading blogs - on the interweb.…

The big geology news right now is the M8 earthquake in American Samoa that generated a killer tsunami (which made it all the way to the Bay Area in California).
Mammoth Mountain in California's Long Valley region.
In more benign, volcano-related news:
The aviation alert level at Redoubt in the…

As fall descends on the northern hemisphere, spring starts in the southern. Luckily for us, it means that we get better views of the southern Andes in Chile ... which means the NASA EO could train one of the many "eyes in the sky" (specifically the EO-1) on Chaiten. The volcano is still erupting,…
