ALASKA VOLCANO OBSERVATORY DAILY UPDATE
U.S. Geological Survey
Monday, June 2, 2014, 1:00 PM AKDT (Monday, June 2, 2014, 21:00 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

The low-level eruption of Pavlof continues. Highly elevated surface temperatures observed in satellite imagery persist at the summit of the volcano, which is consistent with lava at the surface. Clear FAA web camera images from Cold Bay last night showed strong incandescent glowing at the summit, and low-level ash emissions are visible in early morning views. An ash cloud was detected in satellite imagery today extending about 40 km downwind of the volcano. Pilots reported ash emissions to 12,000 ft. ASL this morning. A spatter-fed lava flow down the north flank has been confirmed that generates intermittent flowage events, presumably lahars. Low-level ash clouds have been observed associated with the lava flow as it interacts with glacier ice. The subtle seismicity associated with the eruption is being masked by stronger seismic signals generated by the lava-generated flowage events down the north flank.

SHISHALDIN VOLCANO (VNUM #311360)
54°45'19" N 163°58'16" W, Summit Elevation 9373 ft (2857 m)
Current Volcano Alert Level: WATCH
Current Aviation Color Code: ORANGE

Low-level eruptive activity continues at Shishaldin. Satellite images indicate that elevated temperatures persist. Views of the volcano by web camera were mostly obscured by clouds in the last 24 hours although several clear images showed no activity.

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

No activity was observed at Cleveland today in partly cloudy satellite views.

VENIAMINOF VOLCANO (VNUM #312070)
56°11'52" N 159°23'35" W, Summit Elevation 8225 ft (2507 m)
Current Volcano Alert Level: ADVISORY
Current Aviation Color Code: YELLOW

Seismicity remains slightly above background. Weakly elevated surface temperatures were observed in satellite imagery today which is consistent with cooling lava.

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.
