REDOUBT VOLCANO (VNUM #313030)
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 continues. Seismicity over the past 24 hours remains elevated. The lava dome at the summit continues to grow and may become unstable and could collapse with little or no warning, leading to significant ash emissions and possible lahars in the Drift River Valley.

Vigorous steam emissions are continuing from the margins of the lava dome, and rising to about the summit of the volcano. Rock fall activity continues from the unstable slopes of the lava dome, producing minor ash clouds in the vicinity of the summit. No ash has been detected by satellite or radar data.

AVO is monitoring Redoubt volcano closely and the observatory is staffed 24/7. AVO will provide frequent updates of the volcano's status and the earliest possible warning of significant explosive activity and other hazardous phenomena.

VENIAMINOF VOLCANO (VNUM #312070)
56°11'52" N 159°23'35" W, Summit Elevation 8225 ft (2507 m)
Current Volcano Alert Level: ADVISORY
Current Aviation Color Code: YELLOW

Seismicity at Veniaminof remains elevated. AVO continues to observe small earthquakes and volcanic tremor located near the intra-caldera cone. No unusual activity has been observed on satellite data or by pilots flying in the area.
