Mount Spurr Eruption
Unrest continues at Mount Spurr volcano. Seismicity remains elevated with numerous small, shallow volcanic earthquakes detected beneath the volcano over the past day. Steaming observed in mostly clear web camera images. Nothing of note in satellite data.
AVO continues monitoring activity at Mount Spurr for signals indicating that the volcano is moving closer to an eruption. Based on previous eruptions, changes from current activity in the earthquakes, ground deformation, summit lake conditions, and fumarolic activity would be expected if magma began to move closer to the surface. Therefore, if an eruption occurred, it would be preceded by additional signals allowing warning.
