AVO is raising the Aviation Color Code to YELLOW and the Volcano Alert Level to ADVISORY at Redoubt volcano. At roughly 16:00 AKDT yesterday Dec. 27 (0100 Dec. 28 UTC) a series of small repetitive earthquakes began occurring in the vicinity of the volcano's summit. Activity is continuing this morning. See www.avo.alaska.edu...
These earthquakes may be precursory to renewed eruptive activity at the volcano and increased instability of the lava dome. Whether this will result in explosive activity or failure of the lava dome is unknown at this time. However, there is a heightened possibility of volcanic activity that would produce a volcanic ash cloud, pyroclastic avalanches, and lahars and flooding down the Drift River.

First that volcano in the Philipines starts to become active...then Yellowstone...now Redoubt ....is something happening?
2010-01-01 11:57:13 - Weekly Update
The swarm of shallow, small earthquakes that began last Sunday, December 27 at Redoubt Volcano has greatly diminished or ceased. Close-in aerial observations of the new lava dome yesterday indicated no disruption at the surface and no sign of instability. Photographs and thermal camera imaging of the 2009 lava dome showed continued high temperature areas on the surface of the dome which is expected as the thick pile of blocky lava slowly cools in place. Magmatic gas emission from the dome area, however, is somewhat elevated compared to the last measurement in early November.
The Aviation Color Code remains YELLOW and the Volcano Alert Level remains ADVISORY.
AVO is continuing to evaluate information to interpret this week's uptick in seismicity and gas output. One explanation involves input of new magma or remobilization of existing magma within volcano's shallow plumbing system. This process appears to have ceased or paused. It remains possible that activity could reappear, intensify and lead to additional eruptive activity. We would expect a sharp increase in seismicity and other marked changes prior to such activity.
AVO will continue to issue daily status reports as long as the Aviation Color Code and Alert Level are elevated.

Ash can travel a long ways it appears. When St. Helens blew the second time the ash ended up dumping on Northern Idaho and into Montana. It actually destroyed Northern Idaho's economy that year.
