ALASKA VOLCANO OBSERVATORY STATUS REPORT
U.S. Geological Survey
Monday, April 5, 2010, 2:20 PM AKDT (Monday, April 5, 2010, 22:20 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

AVO raised the Aviation Color Code to YELLOW and the Volcano Alert Level to ADVISORY at Redoubt volcano this morning. A series of small repetitive earthquakes began at 01:44 AKDT (0944 UTC) this today in the vicinity of the volcano's summit. Activity is continuing this afternoon. See http://www.avo.alaska.edu/webicorders/Redoubt/RSO_EHZ_AV.php

These earthquakes may be precursory to renewed eruptive activity at the volcano and increased instability of the lava dome. Whether this will result in explosive activity or failure of the lava dome is unknown at this time. However, there is a heightened possibility of volcanic activity that would produce a volcanic ash cloud, pyroclastic avalanches, and lahars and flooding down the Drift River.
