Mount St Helens erupts!

A major steam explosion occurred about 25 minutes ago. Unfortuntely, there's not much to see on the Volcanocam at the moment. However, there may change after night fall when the incandescence from the lava may be visible.

The plume is apparently now greater than 10,000 m high...

The eruption is clearly visible on the webicorder (seismometer) traces as a significant increase in activity beginning around 5:30pm.

Stay tuned for updates...

Yeah, Darryl! A decent sized eruptive episode, largest yet since the mountain re-awakened in late September, 2004!!!

Steam and ash cloud rose to 36,000 feet, and is drifting over Eastern Washington now. Reports of ashfall in many communities to the East and NE of the mountain, and planes are being kept out of the area.

Great photos and videos of the eruption are available at the Cascades Volcano Observator website:
