AVO VOLCANO ACTIVITY NOTIFICATION

ALASKA VOLCANO OBSERVATORY DAILY UPDATE
U.S. Geological Survey
Saturday, June 28, 2014, 12:11 PM AKDT (Saturday, June 28, 2014, 20:11 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

Low-level eruptive activity continues. Consistently elevated temperatures at the summit of Shishaldin Volcano were recorded in satellite images over the past 24 hours. No significant seismicity was noted. Web camera images were obscured by fog and clouds.

SEMISOPOCHNOI VOLCANO (VNUM #311060)
51°55'44" N 179°35'52" E, Summit Elevation 2625 ft (800 m)
Current Volcano Alert Level: ADVISORY
Current Aviation Color Code: YELLOW

The Semispochnoi earthquake swarm that began on June 9 continues. No sign of activity was noted in most cloudy satellite images over the past 24 hours.

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 volcanic activity was observed in mostly cloudy satellite images over the past 24 hours.

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

No sign of eruptive activity. Weak thermal signals from recent lava flows persist in satellite images. Small, discrete seismic events continue, however, and eruptive activity could resume at any time with little or no warning.

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

No activity of concern was observed in clear satellite images and web camera views over the past 24 hours. A plume of steam and possibly minor volcanic gas persists from the intracaldera cone. Seismicity remains slightly above background.

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.
