ALASKA VOLCANO OBSERVATORY DAILY UPDATE
U.S. Geological Survey
Thursday, March 15, 2018, 12:23 PM AKDT (Thursday, March 15, 2018, 20:23 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
Unrest continues at Cleveland volcano. A small explosion occurred today, March 15, at 6:19 UTC (10:19 pm March 14 AKDT) and was detected in seismic and infrasound data. Subsequent cloudy satellite images showed no ash cloud. Nothing else of significance was observed in 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.
