ALASKA VOLCANO OBSERVATORY INFORMATION STATEMENT
U.S. Geological Survey
Thursday, June 5, 2014, 5:16 AM AKDT (Thursday, June 5, 2014, 13:16 UTC)

PAVLOF VOLCANO (VNUM #312030)
55°25'2" N 161°53'37" W, Summit Elevation 8261 ft (2518 m)
Current Volcano Alert Level: WATCH
Current Aviation Color Code: ORANGE

Two strong explosions were recorded in seismic data early this morning (10:05 and 10:45 UTC; 02:05 and 02:45 AKDT) at Pavlof. Lightning was detected by the WWLLN system but there is no indication of higher altitude ash in satellite data. Meteorological cloud tops are up to 29,000 ft. ASL and winds are to the west-southwest.

CLEVELAND VOLCANO (VNUM #311240)
52°49'20" N 169°56'42" W, Summit Elevation 5676 ft (1730 m)
Current Volcano Alert Level: ADVISORY
Current Aviation Color Code: YELLOW

An explosion occurred at Cleveland volcano at about 06:08 UTC as detected on the Dillingham acoutstic infrasound array and at seismic stations at Korovin Volcano. The event appears to have been of short duration and with similar amplitude to previous explosions at Cleveland. The last explosions at Cleveland were on February 25, 2014. No ash signals were observed in satellite images.

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.
