Current Level of Concern Color Code: ORANGE
Seismicity at Augustine Volcano increased slightly last night and again this afternoon. Satellite observations indicate that faint thermal anomalies persist at the volcano.
Intervals of increased seismicity such as those observed over the last 24 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 and low-level seismicity during an eruptive phase are not unusual and have occurred during past eruptive episodes of Augustine in 1976 and 1986. The decline in seismicity since the last explosive event on January 17 does not necessarily mean that explosive eruptions have ended and they could resume with little or no warning. AVO is monitoring the situation closely and the observatory is staffed 24/7.
