Eruptions

Back from the field

I am back from my trek through the Oregon and California Cascades – including stops at Lassen Peak/Chaos Crags, Hood, Three Sisters and Crater Lake (an added bonus). I’ll try to catch up on the volcano news I’ve missed and post on anything exciting that happened soon, but otherwise I’ll be posting new news as…

Eruptions out of the office

I will be away from Eruptions for the next 2 weeks or so. I won’t be on vacation, I will actually be out on volcanoes themselves doing some much-needed fieldwork. It is a three volcano tour, starting with a trip to Lassen Peak to get a guided view with Michael Clynne of the USGS (the world…

Sulfur dioxide from Kasatochi

Sorry about the lack of update. Having no internet while moving will do that! I did see an email this morning that had some interesting information about the amount of sulfur dioxide emitted by Kasatochi (Alaska) during the current eruption (thanks to Simon Carn, UMBC): “The August 7-8 eruption of Kasatochi volcano (Aleutian Islands)produced a…

Details on the Kasatochi eruption

This article sums up a lot of the events that led up to the Kasatochi (Alaska) eruption last week from the point of view of the biologists on the island itself right before it erupted. There are some great descriptions of the whole island shaking for 10 minutes, and they also offer some exciting new…

I’ll be brief (as I’m in the middle of moving), but I did see a report that activity at Chaiten is increasing yet again. This seems like the operating mode for this volcano, with a waxing and waning of intensity, since the volcano started erupting on May 2. The latest report indicates renewed ash emissions…

Kasatochi from space

NASA posted a nice image of the ash plume from the current eruption at Kasatochi (Alaska) showing the brown/grey ash mixing with white clouds over the Pacific. Not much else to report on the eruption other than that AVO reported that seismicity remained low from August 10-12.

We had a brief bit over the weekend that Mayon in the Philippines had a number of small explosive events (less the one minute worth of activity). However, Philvolcs (Philippine Institute of Volcanology and Seismology) is downplaying the idea that a major eruption is in the works. There have been a number of explosion-related seismic events…

New flows at Kilauea

Not to feel left out from all the action going on in Alaska, Kilauea in Hawai’i has a new lava flow issuing from the Thankgiving Eve Breakout (TEB) vent area. It sounds like a fairly small flow and none of the flows have reached the ocean. The TEB was the November 21, 2007 event where activity…

The current eruption at Kasatochi is causing a lot of flight cancellations for flights from Alaska to points in the continental US. The ash is swirling its way around the Aleutians along flight lanes (see above), with the ash drifting southeast over the Alaska Panhandle and could hamper air travel in Alaska and Canada for…

Mayon being watched

Mayon, a volcano in the Philippines, is on watch for an eruption after experiencing small explosions. Philvolcs, (short for the Philippine Institute of Volcanology and Seismology), reports a small ash emission – ~200 feet – but they feel that there isn’t an imminent threat of an eruption. Mayon is an relatively active volcano in the Philippines,…
