"MOUNT SPURR: VOLCANO ADVISORY (YELLOW STAGE)

Unrest continues at Mount Spurr, with numerous small, shallow volcanic earthquakes detected beneath the volcano. Earthquakes are primarily being located under the north side of the Spurr summit vent over the past day. Views from the CTK camera have been obscured by snow cover over the past few days and satellite observations were obscured by clouds.

The Alaska Volcano Observatory(AVO) continues to monitor activity at Mount Spurr for signals that would indicate that the volcano is moving closer to an eruption. Based on previous eruptions, changes from current activity in the earthquakes, ground deformation, summit lake, and fumaroles would be expected if magma began to move closer to the surface. Therefore, it is very likely that if an eruption were to occur it would be preceded by additional signals that would allow advance warning."
