AVO VOLCANO ACTIVITY NOTIFICATION

ALASKA VOLCANO OBSERVATORY DAILY UPDATE
U.S. Geological Survey
Sunday, May 4, 2014, 12:47 PM AKDT (Sunday, May 4, 2014, 20:47 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 indicative of continued low-level eruptive activity were evident in satellite data over the past day. Clear webcam images of the volcano this morning show nothing unusual occurring and no obvious steam plume is present. The elevated surface temperatures are likely the result of lava effusion within the summit crater. AVO has received no reports of activity or unrest 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. Faint thermal signals were observed in partly cloudy satellite images over the past 24 hours, which are likely a result of the cooling lava flows that were emplaced in 2013. Clear web camera views of the intracladera cone this morning showed nothing unusual.

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

Nothing unusual was observed in partly cloudy satellite views of the volcano over the past day. AVO has received no reports of activity or unrest during 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.
