ALASKA VOLCANO OBSERVATORY DAILY UPDATE
U.S. Geological Survey
Thursday, September 5, 2013, 11:25 AM AKDT (Thursday, September 5, 2013, 19:25 UTC)
56°11'52" N 159°23'35" W,
Summit Elevation 8225 ft (2507 m)
Current Volcano Alert Level: WATCH
Current Aviation Color Code: ORANGE
Continuous seismic tremor continues. The level of seismicity is lower than observed August 30 to September 2. Low-level ash emission from the active intracaldera cone is likely occurring, though the view from the FAA webcam in Perryville is obscured by clouds today. Elevated surface temperatures have been detected over the past 24 hours in satellite images, consistent with lava effusion.
Ash fall from current activity is not expected to be significant and likely will be less than 1/16 inch, although areas within a few miles of the active cone could receive thicker amounts of ash fall. Information about volcanic ash and its potential effects can be found on the AVO web page (www.avo.alaska.edu).
