Redoubt Update for 5/1/2009

Redoubt in April 2009 with Anchorage in the foreground (along with two F-22 Raptors). Image courtesy of Calvin Hall. It has been quite some time since I talked about Redoubt, mostly because the volcano has been in the “slow extrusion of a dome” mode that has not generated much beyond impressive steam (with some ash)…

Volcano Profile: Mt. Hood

Back in the days when Eruptions was on WordPress, I held a vote about what volcano should be the next to be profiled on this blog. The winner was Mt. Hood in Oregon, and after much waiting, the profile is here. I will actually be out of town until Monday doing some house shopping in…

Mt. Baker in Washington. Image taken by John Scurlock. Eruptions reader Robert Somerville brought to my attention the Mount Baker Volcano Research Center, a “clearinghouse for research on Mt. Baker” in Washington state. The center is a non-profit organization that is affiliated with the Geology Department at Western Washington University – and from the looks…

Llaima eruption from space

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 the ash plume of the eruption…

Llaima eruption intensifies

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 and the ash from the eruption…

Today looks to be a doubleheader of volcano news: Redoubt Image courtesy of AVO/USGS, taken by Rick Wessels. An infrared image of the north slope of Redoubt showing the hot, new dome material and hot block & ash flows confined to the valley. At 11:30 AM yesterday, AVO put Redoubt back to Orange/Watch alert status…

Image courtesy of AVO/USGS by James Isaak. Photo taken 3/31/2009. 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 crude oil from the Chevron-owned Drift…

Image courtesy of Calvin Hall. Taken 3/28/2009 during an eruption at 10:59 AM3:28 PM. 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 two of my favorite things…

Image courtesy of AVO/USGS by Game McGimsey Following the provided script, Redoubt erupted again last night, producing a 32,000 foot / 10,000 meter ash column that prompted a new ash fall warning for the Kenai Peninsula area. Thus far, though, there have been few reports of major damage being caused by the ash fall. Alaska…
