Eruptive activity continues at Okmok Volcano. Low-level ash emissions have been observed in satellite data at Okmok though most of the past 24 hours. However, since 14:30 UTC today the level of seismic activity has gradually decreased to near pre-eruption levels. Satellite data show that ash is no longer being emitted since seismicity levels decreased.

Seismic activity at Kasatochi continues to be detected by the AVO seismic network on Great Sitkin Island 25 miles to the west. Clouds have obscured the volcano in satellite views. No plumes have been observed, but people on Adak reported smelling sulfur Sunday afternoon.

Eruptive activity continues at Okmok Volcano. The seismic intensity and tremor duration are still above background levels. Satellite data from the past 12 hours indicates small ash emissions have occurred intermittently and are drifting generally to the south and not reaching higher than 10,000 to 15,000 feet.

Clouds have obscured the volcano in satellite views. No plumes or other observations of activity have been reported.
