Current Level of Concern Color Code: ORANGE
Small earthquakes were detected at Augustine volcano throughout the night. A large earthquake in the Banda Sea, with a preliminary magnitude of 7.7 according to the National Earthquake Information Center, was detected at Augustine seismic stations beginning at 08:11 AST (17:11 UTC).
Intervals of increased seismicity such as those observed over the last 36 hours are not unusual. The type of seismicity being observed at the volcano is consistent with movement of magma within the edifice.
Periods of quiescence have occurred during past eruptive episodes of Augustine in 1976 and 1986. Explosive eruptions could resume with little or no warning. AVO is monitoring the situation closely and the observatory is staffed 24/7.
