Wednesday Jul 16, 2008 09:11 AM |
Okmok Volcano continues to erupt. Seismicity, though below this weekend's intensity, has remained steady over the last 24 hours. Satellite data continue to show a long (~250 km) plume moving east; the height of the plume is approximately 30,000 ft above sea level.

The large red mass is from the main explosive phase on 12 July at 2130 UTC and is at an estimated height of 50,000 ft above sea level. The north-south dimension of this cloud is about 850 miles. Current emissions from the volcano are at a lower altitude of approximately 30,000 to 35,000 feet. Other OMI data (not shown) indicate that volcanic ash is mixed with the sulfur dioxide cloud.
