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 strong eruption at Okmok continues based on ongoing seismic activity and satellite observations. Ash emissions continue reaching altitudes of 30,000 - 35,000 ft asl, and are posing a large hazard to all aircraft in the area.
