SI/USGS Weekly Volcano Activity Report for 9/16-9/22/2009

I missed the weekly report last week (sorry), but here is the new USGS/SI volcano activity report.

Highlights include:

• Shiveluch in Kamchatka is still erupting away, producing ~7 km / 20,000 foot ash columns as the lava dome grows. There has also been pyroclastic flows spotted emanating from the new lava dome.
• There was a report of a ~7.5 km / 25,000 foot ash-and-steam plume from El Reventador in Ecuador.
• More small plumes and incandescent lava bombs were spotted at the Tavurvur Crater at Rabaul in Papau New Guinea
