Unrest at Redoubt Volcano continues. Seismicity levels have remained relatively constant since yesterday afternoon at 3:30 PM AKST, and are still well above background. Clear web camera views currently show a steam plume rising to roughly 10,500 ft asl.

An observation flight to the volcano yesterday showed an increase in steaming, enlargement of melt features in the summit glacier, and increased runoff along the margins of the Drift glacier. No evidence of eruptive activity was observed. An observation and gas-measurement flight is headed to the volcano this afternoon.

Staff are currently monitoring the volcano 24 hours a day. We will issue further information as it becomes available.
