LEVEL OF CONCERN COLOR CODE: RED
LAST LEVEL OF CONCERN: ORANGE
Seismicity at Pavlof volcano has continued to increase and has now reached levels indicative of very strong eruptive activity. Although the volcano is not currently visible, the seiemicity is such that ash plumes could be expected to reach altitudes of 30,000 feet or more above sea level and AVO has raised the Level of Concern Color Code to Red. AVO will continue to monitor the volcano closely and issue further updates as the situation warrants.
The nearest towns to the volcano are Cold Bay (37 mi), King
Cove (30 mi), Sand Point (60 mi), and Nelson Lagoon (50
mi). If the eruption intensifies, these towns could expect
light ash fall depending on wind direction and continuing
eruptive activity. Eruptive activity could cause mudflows
and some flooding in the Cathedral River valley north of the
volcano. Airborne ash hazards to aircraft may be
considerable if a large explosive event occurs but are much
less severe during a typical Strombolian phase.
AVO has a seismic network of six stations near the volcano.
