I'm breaking this out of the comments of the "Redoubt Erupts!" post just to keep things up-to-date.
As of now, we know:
- At least 5 explosions have occurred as part of the eruption
- Ash has drifted to the NNE and W - both as seen on radar and as reports of ash falling in Skwentna and the Chuitna area - and so far missing populated areas (see above)
- The ash cloud is believe to have reached as high as 50,000 feet/15,000 meters - prompting an aviation warning/restrictions and cancellation of flights out of Anchorage's Ted Stevens Airpor UPDATE 2PM Pacific 3/23: Some more flight information, including cancellations from Fairbanks as well.
- No images of the eruptions so far, but AVO will attempt an overflight later today (3/23)
- The Hut Webcam is out, but it is not known if this is because of the eruption, snow or even dead batteries. The Cook Inlet webcam is just cloudy.
- The Air Force is only letting essential personnel report to work at Elmendorf AFB.
- No evidence of lahars or pyroclastic flows - so far.

I don't have many details, but the largest eruption so far in this eruptive stage at Redoubt occurred at 9:24 AM (Alaska Time), producing a 65,000 foot / 20,000 meter ash column! Yes, you read that right, a 20-km ash column! This is by far the largest ash…
Mt. Redoubt in March 2009, prior to erupting
At ~10:30 PM (Alaskan Time) last night, Mt. Redoubt erupted. AVO and the Anchorage VAAC issued a Red Alert for ash as high as 50,000 feet (15,000 meters) around the volcano. Information is scarce about the exact nature of the ash cloud because of the…
Redoubt seems to be setting its pattern for this part of the new eruptive period. There was another small explosion this morning that produced at 15,000 foot / 5,000 meter ash column that moved to the NNW. The seismicity has settled down since the early morning eruption today (3/25) as well.
These…
Make that 60,000 feet/18,000 meters.
Here is AVO's latest information statement. Not much new other than the expected helicopter flight and potential repair of the hut telemetry as the conditions permit. They are also reporting (not in the linked page) that the last large explosion was at 4:30 AM this morning (Alaska time).
The only real imagery I've seen so far are thermal images of ash plumes from the Earth Observatory.
Got to love writer for this one. Good timing with the current media.
