AVO VOLCANO ACTIVITY NOTIFICATION

ALASKA VOLCANO OBSERVATORY STATUS REPORT
U.S. Geological Survey
Saturday, March 21, 2009, 2:23 PM AKDT (Saturday, March 21, 2009, 22:23 UTC)


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

Shallow earthquake activity under the volcano that began yesterday continues. Activity is primarily seen on the stations nearest the summit, though some events are also recorded at farther-out stations. A steam plume rising as high as approximately a thousand feet above the volcano is visible on the web cameras, but no explosive or ash activity such as occurred last Sunday has been identified. AVO is watching the activity closely but remaining at Yellow/Advisory at this time.

It is still possible for unrest at the volcano to change rapidly, and seismic activity or other signs of unrest could escalate over time periods as short as 24 hours or less. Minor explosive activity such as was seen March 15 could occur with little or no warning.

A field crew at the volcano today installed one non-telemetered seismometer and will try for a second later this afternoon.


CLEVELAND VOLCANO (VNUM #311240)
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 has received no new reports of activity at Cleveland over the past 24 hours. Satellite views have been obscured by clouds.
