ALASKA VOLCANO OBSERVATORY DAILY UPDATE
U.S. Geological Survey
Monday, November 24, 2014, 12:18 PM AKST (Monday, November 24, 2014, 21:18 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

Elevated seismic activity at Pavlof continues. Nothing unusual was observed in satellite and webcam views over the past day. A faint thermal signal was detected at the summit in a few cloud free views this morning and this probably reflects still hot, but cooling lava near the vent. Eruptive activity may not be occurring at present, or is happening at a very low level. Pauses in vigorous eruptive activity of days to weeks are common during eruptive episodes of Pavlof Volcano. A return to more robust eruptive activity remains possible and could occur with little or no warning.

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

Seismic activity has increased over the past 24 hours and remains elevated. No ash plumes have been detected and satellite images show strongly elevated surface temperatures near the volcano's summit. Partly clear web camera images this morning show 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

Faint thermal signal at summit observed in satellite views this morning, otherwise, the volcano has been mostly obscured by clouds over the past day. Seismicity remains low.

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.
