ALASKA VOLCANO OBSERVATORY DAILY UPDATE

Tuesday, June 3, 2014 12:33 PM AKDT (Tuesday, June 3, 2014 20:33 UTC)

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

Current Aviation Color Code: RED

The eruption of Pavlof Volcano continues. After elevation to Aviation Color Code RED yesterday late afternoon, seismic tremor began to decrease somewhat about 0800 UTC (11 pm AKDT) last night. Nighttime web camera images from Cold Bay showed intense lava fountaining at the summit and incandescence from the spatter-fed lava flow on the north flank. Seismic tremor increased again this morning and web camera images and pilot reports indicated the ash and steam plume up to 24,000 ft. ASL. Following an overnight shift in wind direction, the main plume is currently being carried south-southwest of the volcano. Lower-level winds (below 10,000 ft) extend west-southwest and may be carrying trace amounts of ash. There are no reports of ash falling in nearby communities.

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 a steam plume rising from the summit.

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 Aviation Color Code: YELLOW
Seismicity remains slightly above background. No elevated surface temperatures were observed in satellite imagery in the past 24 hours.

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.
