LEVEL OF CONCERN COLOR CODE: ORANGE
Last Level of Concern Code: ORANGE
The eruption at Pavlof volcano continues at the same level as yesterday. The seismicity remains at an elevated level similar to yesterday and visual reports this afternoon from pilots and ground observers in Cold Bay indicate an ash plume or plumes reaching to 12,000-16,000 feet ASL and extending for up to 20 miles in a west to northwest direction. Ground observers in Nelson Lagoon 50 miles northeast of the volcano reported vigorous fore fountaining and a lava flow visible last night. Based on the above information, AVO believes the strombolian eruptive activity that has characterized Pavlof since mid-September is continuing. Lava fountaining, lava flows, and ash clouds to 20,000 feet ASL can be expected. The Level of Concern Color Code remains at ORANGE but eruptive activity could increase with little or no warning. AVO will continue to monitor the volcano closely and issue further updates as the situation warrants.
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.
