52°49'24" N169°56'35" W, Summit Elevation 5676 ft (1730 m)
Current Aviation Color Code: ORANGE
Current Volcanic Activity Alert Level: Watch
AVO received a pilot report of an eruption of Mount Cleveland volcano at approximately 0000 UTC (1600 AKDT) today. Satellite data confirmed the presence of a drifting ash cloud moving ENE of the volcano. Based on satellite data, we estimate the height of the cloud to be 20,000 ft. above sea level, though one pilot report had it in excess of 30,000 ft. The eruption started at approximately 2345 UTC (1545 AKDT) and ended shortly thereafter.
AVO is raising the aviation color code to Orange and the volcanic activity alert level to Watch.
Short-duration eruptions such as this have been typical of Cleveland over the last several years. This is the fourth such known eruption this year, the previous one having occurred on August 24. There is no real-time seismic network on Cleveland; AVO monitors Cleveland chiefly by satellite.
ABBREVIATED COLOR CODE KEY (contact AVO for complete description):
GREEN volcano is dormant; normal seismicity and fumarolic activity occurring
YELLOW volcano is restless; eruption may occur
ORANGE volcano is in eruption or eruption may occur at any time
RED significant eruption is occurring or explosive eruption expected at any time
