ALASKA VOLCANO OBSERVATORY DAILY UPDATE U.S. Geological Survey Wednesday, May 9, 2018, 12:01 PM AKDT (Wednesday, May 9, 2018, 20:01 UTC)
52°49'20" N 169°56'42" W,
Summit Elevation 5676 ft (1730 m)
Current Volcano Alert Level: ADVISORY
Current Aviation Color Code: YELLOW
Low-level unrest likely continues at Cleveland volcano. No significant activity was observed in cloudy satellite images or local monitoring data over the past day.
Cleveland volcano is monitored by only two seismic stations, which restricts AVO's ability to detect precursory unrest that may lead to an explosive eruption. Rapid detection of an ash-producing eruption may be possible using a combination of seismic, infrasound, lightning, and satellite data.
The Alaska Volcano Observatory is a cooperative program of the U.S. Geological Survey, the University of Alaska Fairbanks Geophysical Institute, and the Alaska Division of Geological and Geophysical Surveys.
