Current activity at Redoubt volcano suggests that a significant explosive event is likely, though not certain, in the coming days. This event could occur at any time with little or no warning. Since about May 2 shallow earthquake activity beneath the actively growing lava dome of Redoubt volcano has been slowly increasing. The growing lava dome is becoming increasingly unstable.
Should a significant explosion occur, the event will likely produce high altitude (>30,000 ft ASL) ash plumes, trace to minor ash fall in parts of south-central Alaska, lahars in the Drift River Valley, and pyroclastic flows in the immediate vicinity of the volcano. AVO continues 24/7 operations and is monitoring the situation closely. AVO will provide frequent updates of the volcano's status and the earliest possible warning of significant explosive activity and other hazardous phenomena.
