eklemetti | October 8, 2009Chaiten 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.
Third Dome Spotted
The latest USGS/SI Weekly Volcanic Activity Report mentions that over the last week, Chaiten experienced what was likely a significant dome collapse of one of the two domes growing in the caldera. People living close enough to the volcano to see the ash plume noticed it became larger and darker on September 29th. Afterwards, visual observations of the caldera by air confirmed that a…

Chaiten in Chile erupting in January 2009. Even after over a year of activity, Eruptions readers are still captivated by the volcano.
Thanks for sending me your questions about volcanoes and volcanism. I'll try to tackle some hear - but as always, keep the questions coming! Send them to
For those of you who have submitted a question but don't see the answer here, do not fret. Likely it just means that I needed to do a little more research into the question and will get to it in a later mailbag!
So, without further ado ...
Mark M.: Here in the Appalachians we have very dense crystalline rock…
eklemetti | April 28, 2009This is another busy Wednesday for me as the Geology Dept. at UC Davis will be hosting Dr. Jacob Lowenstern, USGS scientist and director of the Yellowstone Volcano Observatory. He will be giving the weekly seminar, along with another talk in the evening at Sacramento State as part of the Volcanological Society of Sacramento meeting (which is open to the public for those of you around Sacramento). I'm especially excited for the evening talk entitled "Domestic volcanic unrest and activity in 2009: Kilauea, Redoubt, Yellowstone and Washington, D.C.". I'll be sure to report any fun tidbits.
For…

I am beginning to feel like a broken record, but the latest reports from Chile indicate that the ongoing eruption at Chaiten is ramping back up again, almost 3 months after the initial eruption began. As usual, the nitty-gritty details are limited, but reports of increased ash emissions and seismic activity are heralding this increase in activity.
For certain, Chaiten is one of the most important eruptions in any of our lifetimes. This is really not because of the amount of material that has been erupted (although when all is said and done, it will be a significant volume), but rather for…

The Oregonian reports on the on-going desire to develop geothermal power in the Oregon and California Cascades and backarc. There have been attempted (or at least exploration) to develop geothermal power at Newberry Volcano, Crater Lake and Medicine Lake, but none have ever panned out. Well, it seems like this time it might happen, and I, for one, think it is a good idea. Of course, there are a lot of folks who don't want a geothermal plant anywhere near Newberry, especially with its National Monument designation, but one of these days we'll have to choose between that and higher energy…
