ALASKA VOLCANO OBSERVATORY STATUS REPORT
U.S. Geological Survey
Monday, May 4, 2009, 2:09 PM AKDT (Monday, May 4, 2009, 22:09 UTC)
60°29'7" N 152°44'38" W,
Summit Elevation 10197 ft (3108 m)
Current Volcano Alert Level: WATCH
Current Aviation Color Code: ORANGE
The 2009 eruption of Redoubt volcano continues, with growth of a lava dome in the summit crater. Seismicity remains elevated and is characterized by frequent rockfall signals, numerous small earthquakes, and low levels of volcanic tremor. Clear web camera images show continuous steam emissions rising several thousand feet above the summit and currently moving towards the southeast. These steam emissions may contain minor amounts of ash, but they are too diffuse to be detected by radar. Satellite images show a persistent thermal anomaly consistent with an actively growing lava dome in the summit crater.
Additional explosive events producing ash clouds, ash fall, and mudflows are possible and can occur with little or no warning. AVO is maintaining 24/7 operations in order to quickly detect renewed significant explosive activity and other hazardous phenomena.
