COLOR CODE: ORANGE
The eruption continues at Pavlof Volcano but seismicity, although still strong, has declined from the very high levels of early this morning when the pilot reports and satellite images indicated a summit hot spot, possible lava flow, and a narrow ash plume extending several 10's of miles to the northwest. NWS personnel in Cold Bay had a clear view of the volcano early this afternoon and reported discontinuous bursts of ash rising to only a few hundred feet above the volcano. AVO has therefore downgraded the Level of Concern Color Code to ORANGE. Eruptive activity, however, could increase with little or no warning. AVO will continue to monitor the volcano closely and issue further updates as the situation changes.
Pavlof is located 600 miles southwest of Anchorage. The nearest towns to the volcano are Cold Bay (37 mi SW), King Cove (30 mi SW), Sand Point (60 mi E), and Nelson Lagoon (50 mi NE). AVO has a seismic network of six stations near the volcano.
Seismic activity is monitored in real time at the following volcanoes. Some of the volcanoes listed below may have anomalous seismicity, as noted, but are not
considered to be at a potentially dangerous level of
The seismic swarm that began on 1 August 1996 beneath
Iliamna Volcano continued during the past week at an
average rate of about 3 earthquakes per day.
Spurr, Redoubt, Augustine, Griggs, Katmai, Trident,
Mageik, Martin, Dutton, Akutan, and Makushin volcanoes are
all at or near normal levels of seismicity.
AVO maintains a computerized alarm system capable of
notifying AVO seismologists during non-business hours
should unusual seismic activity occur at monitored Alaskan
