AVO VOLCANO ACTIVITY NOTIFICATION

ALASKA VOLCANO OBSERVATORY STATUS REPORT
U.S. Geological Survey
Tuesday, September 29, 2009, 3:37 PM AKDT (Tuesday, September 29, 2009, 23:37 UTC)


REDOUBT VOLCANO (VNUM #313030)
60°29'7" N 152°44'38" W, Summit Elevation 10197 ft (3108 m)
Current Volcano Alert Level: NORMAL
Current Aviation Color Code: GREEN

AVO lowered the Aviation Color Code to GREEN and the Volcano Alert Code to NORMAL at 10:44 AKDT this morning (please see the VAN/VONA for details). Over the past several months, seismic activity, volcanic gas output, ground deformation, lava dome temperatures, and outward signs of lava dome instability at Redoubt Volcano have been declining. The volcano appears to have returned to its normal background condition and for now poses no immediate threat of eruptive activity. AVO continuously monitors Redoubt with an alarm system that alerts on-call staff of potential unrest.

No further AVO Current Status Reports will be issued for Redoubt Volcano unless a significant change in activity is observed.


SHISHALDIN VOLCANO (VNUM #311360)
54°45'19" N 163°58'16" W, Summit Elevation 9373 ft (2857 m)
Current Volcano Alert Level: ADVISORY
Current Aviation Color Code: YELLOW

Seismic activity at Shishaldin remains low. Satellite and web cam views were cloudy today.
