Just a quick note before I'm off to this ...
Llaima
The SERNAGEOMIN is evaluating whether the alert level at Llaima should be lowered to Yellow in the near future (in spanish). Seismic acitivity at the volcano have come down since the eruptions started a few weeks ago and most of the activity now…

Redoubt from Ninilchik, AK. Image courtesy of Calvin Hall.
It has been a few days since we've talked about Redoubt. Well, it might be because the volcano has settled down for the past week, to the point that AVO put the volcano back to Orange/Watch status last week and hasn't had to go back to Red…

Fernandina, EcuadorFernandina erupting in 2009.
UPDATE 4/13/09 at 12PM: The NASA Earth Observatory has posted a nice MODIS image showing the plume from the Fernandina eruption drifting out over the Pacific.
We have a few more details on the ongoing eruption at Fernandina in the Galapagos Islands.…

It is hard to believe that we are less than one month away from one-year anniversary of the beginning of the eruption at Chaiten (and with it, the one-year anniversary of this blog!) The volcano in southern Chile is…

Fernandina volcano in the Galapagos.
Fernandina in the Galapagos has entered a new eruptive phase according to the Geophysical Institute (GI) at the National University of Ecuador (in spanish). Satellite images show a new crater and ash column from the volcano and the GI will look for evidence of…

Active US volcanoes and volcano observatories
After all the well-publicized words of "a certain governor in the lower forty-eight" (as Sen. Begich (D-AK) likes to call him) the "wasteful" spending on volcano monitoring improvements in the U.S. have become reality. Sec. of the Interior Ken Salazar…

The NASA Earth Observatory (currently celebrating its 10th year) has posted a number of great images of the current eruption of Llaima in Chile, taken from Earth Observing-1 and Terra Satellites. They show both…

Tambora, Indonesia
There are big eruptions, then there are big eruptions. On April 10, 1815, Tambora, a volcano in Indonesia, produced one of the largest eruptions in human history. This eruption produced what became known as the "year without a summer" after the volcanic aerosols from the eruption…

Your weekly dose of volcanic activity. As a sidenote, you can now get placemarks for the weekly activity report via Google Earth. Select "Google Earth Placemarks" from the SI / USGS Weekly Volcanic Activity Report page.
Highlights of this week's report:
New explosions at Ebeko. See my article today…

Llaima in Chile erupting in 2009.
A quick note to pass along about the ongoing eruption at Llaima in Chile. The eruption did seem to be waning earlier in the week, but the news now is that debris from the eruption is partially blocking the vent. The cone of pyroclastic material (tephra) that has…

Back in the ol' Wordpress days, I did try to have a Mailbag column here on Eruptions. I'd like to restart that here on ScienceBlogs, so if you have any volcano-related questions (or heck, any questions), please email them to me at ewklemett (at symbol) gmail (dot) com. After I get enough questions…

Canlaon volcano, Philippines
Geothermal energy is one of those sources of energy that might be able to solve a lot of the planet's energy problems - heck, the Earth has a lot of heat it is trying to get rid of, so taking that heat and turning into energy seems like an easy (and clean?) way to stop…

To me, one volcanic arc about which I wish I knew more is the Kuril-Kamchatka arc. I'm well aware of how active it is, with giants composite volcanoes like Bezymianny, Koryak, Klyuchevskoi and many, many others. This arc of volcanoes,…

Llaima erupting at night in April 2009.
Brief update for those of you following the somewhat spectacular eruption (above and below) going on at Llaima in Chile. The latest reports indicate the eruption is waning (in spanish) with less ash and explosions (in spanish) being produced. However, ONEMI,…

Today's update will be relatively brief: AVO has returned Redoubt to Orange/Watch status after this weekend's eruptions. The new dome continues to grow and this is accompanied by the usual volcanic…

Popocatépetl from the ISS on January 23, 2001
It might be (and is likely) just normal behavior for Popocatépetl in Mexico, but the volcano produced six plumes over the last 24 hours, according to a report out of Mexico City (in spanish). Officials from El Centro Nacional de Prevención de…

Ulawun Volcano, Papau New Guinea, one of the "Decade Volcanoes"
There was some discussion earlier about the so-called "Decade Volcanoes", so I thought I'd elaborate a bit on them (doubly so in light of certain other lists.) These volcanoes are defined by IAVCEI - the International Association of…

Not much new to report about the eruption at Redoubt beyond the fact that it continues. AVO has kept the warning level at Red/Warning after briefly dropping it to Orange/Watch on Friday night. The 15,000 foot / 5…

Llaima erupting in April 2009.
Just a quick note about the eruption currently ongoing at Llaima in Chile. The volcano continues to explosively (and effusively) erupt, sending ash ~22,000 feet / 7,000 meters into the air. This eruption has produced 37 hours of intense eruption (in spanish) so far…

Today looks to be a doubleheader of volcano news:

Hunga Tonga Hunga Ha'apai, taken in late March 2009
Redoubt did the tried-and-true American trick of shoving news of volcanoes in other parts of the world off the news pages, but shockingly, these international volcanoes continued to erupt. Remember that volcano in Tonga? Hunga Tonga Hunga Ha'aapi…

No, this isn't Battlestar Galactica, but the same can be said for the Drift River Oil Terminal: this has all happened before and will all happen again. Coast Guard officials have (finally) decided to move ~6.3 million gallons of…

UPDATE 4/2/2009 at 11 AM Pacific: I'm moving this up from the comments, but Eruptions reader Doug Cole pointed out (and I have no idea how I missed this) that Redoubt has a new webcam! This one is at the DFR…

For those of you looking for real volcanic eruption news (no, there was no "Yellowstone eruption"), here is this week's SI/USGS Volcano Activity Report.
And speaking of April Fools Jokes, this is by far my favorite (mostly by its combination of volcanoes and baseball. How could you go wrong with…

Photo courtesy of Calvin Hall. Taken from March 28, 2009, 50 miles from Redoubt.
Redoubt continues to huff and puff, with an almost constant ash plume of ~15,000 feet / 5,000 meters. This after ~4 PM (Alaska Time), an explosion produced a 25,000 foot / 8,000 meter ash column that disrupted flights…

Yellowstone Lake eruption, April 1, 2009
Well, after all the seismicity and uplift at Yellowstone caldera over the last few years, something finally happened. Early this morning, without much warning, an eruption occurred in Yellowstone Lake (see above) and sent steam and ash up 50,000 feet above…

I have to admit, I've only been perpherially following the earthquake swarm currently going on in Southern California, near the end of one of the strands of the San Andreas fault out below the Salton Sea (see the bottom of the map above).…

Goma after the 2002 Eruption of Nyiragongo
The activity at Redoubt has captivated a lot of us, but in the grand scheme of things, its eruption are more likely to caused inconvenience and property damage rather than dramatically loss of life (unless something huge and unexpected occurs). However,…

Redoubt did not stray from its pattern of explosive eruptions producing >20,000 foot / 10,000 meter ash columns over the weekend. However, what did change was the wind, and because of that, Anchorage began to feel the…
