Yep, More Eruptions

There were 3 more eruptions, 2 last night around mid-night, and the other at 8:40am. We were under an ash watch for a while today due to those, but I didn’t see any. It’s snow a little right now, has most the day, but the temp is pushing 40*F, but haven’t seen any ash in the snow, it’s all whte. The Seismicity at Redoubt has increased a bit in the past hour, we’ll see if anything be comes of it. It has been too cloudy today for any views from the webcam, or anywhere else for that matter, of Redoubt.

This is the first day, for a while now, that has been very overcast all day, low grey clouds with wet snow flakes. I hope it clears a bit so I can get some photos this weekend. I don’t mind a few clouds, even mostly cloudy, it makes photos more interesting. Can’t even see the mountains today, with the clouds laying so low and heavy.

Well, as I type this, another eruption has happened.

At approximately 17:35 AKDT (01:35 UTC) another explosive eruption occurred at Redoubt volcano. National Weather Service reports an ash cloud height of 40,000 feet above sea level.

This is just a quick post for an update on Redoubt blowing her top again.

From ADN:
Redoubt erupted twice this morning, including a huge explosion at 9:24 that sent a cloud of ash to 65,000 feet, higher than any since the mountain came to life on Sunday night.

Alaska Airlines announced today that it’s canceled all flights in and out of Anchorage for the rest of the day, and other airlines are canceling flights as well.

The following from AVO:
2009-03-26 12:33:56 – Status Report
A large eruption of Redoubt volcano occurred at 09:24 AKDT (17:24 UTC) this morning. National Weather Service reports the cloud height to be at least 65,000 ft above sea level and pilot reports indicated a plume height of 60,000 ft. Since this event, a few smaller events have occurred but these did not generate plumes above about 20,000 feet.

The eruption at 9:24 AKDT also produced a lahar in the Drift River valley that was detected by seismic instruments.

An ashfall advisory is in effect until 4 PM for the western Kenai Peninsula. High level ash (above 30,000 feet) is forecast to pass over Anchorage, but is not expected to produce ash fall. For more information refer to the NWS Redoubt Coordination web page ( for latest ash cloud information.

AVO is raising the aviation color code to Red and the alert level to Warning at Redoubt volcano. An explosive event beginning at roughly 08:34 AKDT has produced an eruption cloud to at least 30,000 ft. above sea level. The event continues.

Heres a cool one.

Another Update, Why Not.

Well, the last eruption was last night, none so far today, though the day isn’t over yet. Last nights eruption had an ash cloud that is estimated to be at least 50,000 ft above sea level based on NWS radar.

At home, we’ve had a pretty nice day, it reached 51*F with mostly sunny skies, with grey in the clouds to the southwest.

As for Redoubt’s eruptive status, geologists said it appears a dome is building in Redoubt’s crater. The dome, they say, could collapse and trigger another eruption.

The difficult thing with these dome-building eruptions is it is very difficult to give short-term warning, because these things can go unstable and fail very quickly, putting an ash plume up to significant heights,” said Stephanie Prejean, a geophysicist.

A similar dome-building episode occurred on Redoubt when it erupted in 1989 and 1990, according to the AVO. The mountain erupted a total of 20 times.

The AVO’s best guess: Redoubt is not finished yet.

Here is a snowmoble path through some of the ash fall.


Another Explosion

This is from a webcam that is monitoring the volcano. You can clearly see the ash cloud. This was at about 7:50pm last night, 10 minutes after another explosion.

Redoubt Update

Right now the skies are partly cloudy, with a bit of haze. Looking to the south, you can see some quite dark/gray clouds. AVO is reporting some ash far here in Wasilla, I think it must be a bit north of us, we haven’t seen any here at home. Around here, Wasilla, everyone is mostly carrying on as usual, going to work, shopping and so on. The ash fall is all depending on the wind direction, and right now it’s not in the right direction to really spead any ash here, though that can change at any time.

I still think this is really cool.

From AVO:
Current Status and Observations
Beginning last night (Sunday March 22, 2009) at approximately 22:38 AKDT, Redoubt Volcano produced a series of five explosive eruptions that each lasted from four to thirty minutes. The last one ended at 5:00 AM AKDT this morning (March 23). National Weather Service radar, pilot reports, and AVO analysis of satellite imagery suggest that these events produced ash clouds that reached 60,000 ft above sea level (asl), with the bulk of the ash volume between 25 – 30,000 ft asl. Traces of ash fall have been reported in Skwentna, Talkeetna, Wasilla, and Trapper Creek.
