'Thar She Blows!


Mt. Redoubt finally erupted after a few intense weeks of seismologists and staff at the Alaska Volcano Observatory being on high alert. Air traffic was either cancelled or diverted yesterday and again last night after the volcano blew ash 60,00 feet into the air.  Last night's blast was the sixth such explosion since Sunday March 22, when Mt. Redoubt first erupted sending a volcanic plume into the air. As of 1:00 pm today Aviation color code remains Red. Alaska Airlines listed that flights in and out of Anchorage have resumed, which is good news for us because we are going to Seattle again and our flight (hopefully) is scheduled to leave early this evening....

Hi Anne and Christine! Yes, we made it (delayed) to Seattle...rainy today. Mt. Redoubt is about 150 air miles from Anchorage. What's tricky is the ash fallout can blow anywhere. Fortunately the latest ash blew Northeast to Talkeetna and away from the Kenai Peninsula and Anchorage and major airports. Ash is very destructive and dangerous. Click on the AVO link and you can see a good map, plus it's is a very interesting web site with some great historical images.

**Redoubt Volcano Latest Observations

Seismicity has been relatively quiet for the past several hours since a brief explosive event at about 5:12 AKDT this morning. A minor ash plume may have been produced by this event, but it does not appear to have reached more than 15,000 ft above sea level.

It's the beauty of Mother Nature... always having that ability to humble us!

A small explosive event occurred at 10:17 AKDT this morning. The plume from this event was not detected by radar, indicating that it did not rise above approximately 12,000 ft asl or contained very little ash. This explosion triggered a flowage event on the north flank of the volcano as indicated by seismicity. Since this event seismicity at the volcano has remained steady, but low level volcanic tremor.
