ALASKA VOLCANO OBSERVATORY DAILY UPDATE
U.S. Geological Survey
Tuesday, July 23, 2013, 9:49 AM AKDT (Tuesday, July 23, 2013, 17:49 UTC)


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

Seismicity remains at low levels at Pavlof. Elevated surface temperatures, consistent with cooling lava flows, were detected in satellite data over the past 24 hours. No ash or gas emissions have been detected in satellite data, web camera images, or reported by pilots.

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

Nearly continuous, low-level volcanic tremor continues to be seen in seismic data. Elevated surface temperatures at the intracaldera cone of Veniaminof volcano were detected in satellite data today. Incandescence in night-time views and low-level ash and steam plumes were observed in images from the FAA web camera positioned in Perryville. Available data indicate an ongoing low-level eruption characterized by intermittent effusion of lava and emission of minor amounts of ash and steam.

52°49'20" N 169°56'42" W, Summit Elevation 5676 ft (1730 m)
Current Volcano Alert Level: ADVISORY
Current Aviation Color Code: YELLOW
