AVO VOLCANO ACTIVITY NOTIFICATION

ALASKA VOLCANO OBSERVATORY DAILY UPDATE
U.S. Geological Survey
Tuesday, May 6, 2014, 12:17 PM AKDT (Tuesday, May 6, 2014, 20:17 UTC)


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

Elevated surface temperatures continue to be evident in satellite data. These observations are consistent with lava effusion within the summit crater. Partly cloudy webcam images of the volcano over the past 24 hours show a small gas and steam plume in the vicinity of Shishaldin's summit. AVO has received no reports of activity over the past 24 hours, and we have yet to observe any significant ash emissions or flowage deposits on the flanks of the volcano.

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 levels. Satellite images over the past 24 hours show weakly elevated surface temperatures consistent with cooling lava flows. Web camera views of the intracladera cone have been cloudy.

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.
