ALASKA VOLCANO OBSERVATORY CURRENT STATUS REPORT
Tuesday, June 30, 2009 12:12 PM AKDT (Tuesday, June 30, 2009 20:12 UTC)


REDOUBT VOLCANO (CAVW #1103-03-)
60°29'7" N 152°44'38" W, Summit Elevation 10197 ft (3108 m)
Current Volcano Alert Level: ADVISORY
Current Aviation Color Code: YELLOW

This morning AVO lowered the Aviation Color Code to Yellow and the Alert Level to Advisory at Redoubt volcano based on a significant decrease in the rate of lava extrusion observed over the past several weeks. It is unknown if this represents the end of the 2009 eruption of Redoubt or if the activity has only paused temporarily and might resume in the next months. The large dome is considered potentially unstable and it could collapse with little to no warning, leading to significant ash production and possible lahars in the Drift River valley.

A more detailed synopsis is forthcoming.

AVO will continue to monitor Redoubt's activity closely, but begin to transition off 24/7 staffing. Later updates will describe operational changes as they occur.

CLEVELAND VOLCANO (CAVW #1101-24-)
52°49'20" N 169°56'42" W, Summit Elevation 5676 ft (1730 m)
Current Volcano Alert Level: ADVISORY
Current Aviation Color Code: YELLOW

AVO received no reports of activity at Cleveland during the past 24 hours. No unusual activity has been observed in partly cloudy satellite views.
