Unrest at Redoubt Volcano continues. AVO conducted an overflight of the volcano this afternoon, and observations confirm that an eruption has not occurred. Increased steaming through previously observed sources in the snow and ice cover were seen and sulfur gas emissions were noted. There was no significant disruption of the glacial ice, nor any apparent increased water discharge down the Drift River.
Seismicity remains well above background levels. Beginning at 00:58 AST (9:58 UTC) this morning, nearly continuous volcanic tremor was recorded at stations near Redoubt's summit, prompting AVO to raise the Aviation Color Code to ORANGE and the Alert Level to WATCH at 02:09 AST (11:09 UTC). Seismicity began to decline at about 05:30 AST (14:30 UTC) this morning, but remains elevated as of this writing. The current activity at Redoubt could be precursory to an eruption, perhaps within hours to days. A further increase in seismicity is expected to accompany an eruption. Staff are currently monitoring the volcano 24 hours a day.------------------------------------------------------ V Healey -- Posted By Breaking News to Break News at 1/26/2009 07:39:00 AM
