Alaska's Mt. Redoubt volcano has had a lot of seismic activity recently and according to sources (to be noted) it is priming for an eruption.

Below is the most recent update from from Alaska's Volcano Observatory (AVO):

"2009-01-30 13:31:16
Intense seismicity continues at Redoubt this afternoon. Clear webcam views, satellite, and radar data indicate that the volcano has not yet erupted. Clouds have moved in to obscure the webcam view over the last several minutes.

The Aviation Color Code remains at ORANGE and the Volcano Alert Level remains at WATCH. "

The remote volcano is a approximately 100 mi from Anchorage, Alaska's most populated city. By reports it does not appear that there is really any immediate harm from its eruption. Although, volcanic ash can shoot over 9 mi high into jet streams which can cause major flight risks.

Volcanic ash is very abrasive and so it can tear away at airplane frames, windshields, and even severely damage the engines.

Redoubt's last eruption was 1989-90 and scientists predict that this eruption will be similar to the last.

For any one in the area or heading that way long clothes are suggested to protect the skin and long goggles for eye protection; also breathing masks are STRONGLY recommended to protect the respiratory system. And expect flight delays do to the dangers of flying in these conditions.

For anyone interested in finding out more the AVO page for Redoubt regularly updates it's activity and even has a webcam that, also regularly, takes photos of it. Check it out here.
