AVO VOLCANO ACTIVITY NOTIFICATION

ALASKA VOLCANO OBSERVATORY DAILY UPDATE
U.S. Geological Survey
Monday, September 16, 2013, 12:33 PM AKDT (Monday, September 16, 2013, 20:33 UTC)


VENIAMINOF VOLCANO (VNUM #312070)
56°11'52" N 159°23'35" W, Summit Elevation 8225 ft (2507 m)
Current Volcano Alert Level: WATCH
Current Aviation Color Code: ORANGE

Seismic tremor continues though at decreased levels compared to prior weeks. Elevated surface temperatures were observed in satellite data over the past 24 hours though the signal is diminished compared to times when effusion of lava was known to be occurring. Elevated temperatures may therefore, be indicative of cooling lava flows or low-level effusion of lava. No eruptive activity was observed in webcam images.
