(11) Volcanic Activity Summary: At about 10:35 AM AKDT seismic activity at Pavlof Volcano increased to levels typically associated with low-level eruptive activity and it is possible that an eruption of Pavlof Volcano may be in progress. Nothing has been observed in satellite data and web camera images, but Pavlof is presently obscured by clouds and no thermal signals or ash emissions are evident through the cloud deck. AVO will be monitoring Pavlof closely and will release further information as warranted.

(14) Remarks: Pavlof Volcano is a snow- and ice-covered stratovolcano located on the southwestern end of the Alaska Peninsula about 953 km (592 mi) southwest of Anchorage. The volcano is about 7 km (4.4 mi) in diameter and has active vents on the north and east sides close to the summit. With over 40 historic eruptions, it is one of the most consistently active volcanoes in the Aleutian arc. Eruptive activity is generally characterized by sporadic Strombolian lava fountaining continuing for a several-month period. Ash plumes as high as 49,000 ft ASL have been generated by past eruptions of Pavlof, and during the 2013 eruption, ash plumes as high as 27,000 feet above sea level extending as much as 500 km (310 mi) beyond the volcano were generated. The nearest community, Cold Bay, is located 60 km (37 miles) to the southwest of Pavlof.
