ALASKA VOLCANO OBSERVATORY DAILY UPDATE
U.S. Geological Survey
Tuesday, May 10, 2016, 11:53 AM AKDT (Tuesday, May 10, 2016, 19:53 UTC)
52°49'20" N 169°56'42" W,
Summit Elevation 5676 ft (1730 m)
Current Volcano Alert Level: WATCH
Current Aviation Color Code: ORANGE
A small explosion occurred at 7:32 AM AKDT (15:32 UTC) today that was detected by infrasound (air pressure) sensors near the volcano. Nothing noteworthy was observed in cloudy satellite views of the volcano since the event. It is possible that a minor amount of ash was generated by the explosion but nothing was detected in satellite data and AVO has received no reports of ash emission from local observers or passing pilots. Volcanic explosions are common at Cleveland Volcano and may continue intermittently at the current level of unrest. These brief events often result in the explosive destruction of lava flows within the summit crater which generates minor amounts of ash and ejecta that fall out on the flanks of the volcano and possibly over parts of Chuginadak Island and the surrounding ocean.
OTHER ALASKA VOLCANOES
Other Alaska volcanoes show no signs of significant unrest: http://www.avo.alaska.edu/activity/
AVO scientists conduct daily checks of earthquake activity at all seismically-monitored volcanoes, examine web camera and satellite images for evidence of airborne ash and elevated surface temperatures, and consult other monitoring data as needed.
