At 5.25pm today (March 8th), Mt. St. Helens erupted for 10 minutes with a large plume of steam and ash rising some 36,000 feet above the crater. The Oregonian and KOIN TV, KIRO TV have additional coverage. Here’s the live Volcano Cam. Google News has the latest.
No deaths or injuries have been reported and the event appears to be over (for now). The ash plume is now moving towards the East (away from Portland). Note that the dailywireless.org staff live in Portland, Oregon which is 35 miles south/southeast of Mt. St. Helens.
The US Geological Survey, in Vancouver Washington, has not yet reported on what caused this but reported that 3 out of 4 monitoring stations inside the crater are no longer working.
Here are some of my Mt. Saint Helens photos shot one day before the last eruption (October 1st, 2004). DailyWireless describes some of the monitoring gear.
