ALASKA VOLCANO OBSERVATORY DAILY UPDATE U.S. Geological Survey Saturday, April 21, 2018, 10:43 AM AKDT (Saturday, April 21, 2018, 18:43 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, though no eruptive activity was observed over the past day in mostly cloudy satellite data, and no significant activity was detected in seismic or infrasound data.
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.
