Redoubt Eruption Round Up

Early ash fall from the eruption of Redoubt is missing populated area, but little is known about the extent of the eruption so far.

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.
