(11) Volcanic Activity Summary: Pavlof Volcano has entered a new phase of eruptive activity. The Aviation Color Code has been increased to Orange and the Volcano Alert Level to Watch. A ground observer in Cold Bay located 60 km (37 miles) from the volcano has reported ash emissions up to 9000 ft above sea level (about 700 ft above the summit). Minor ash emissions were visible in the FAA-operated web camera in Cold Bay beginning around 1:50 UTC on 13 November (4:50 pm AKST on 12 November). Seismic tremor has increased over the past several hours and remains elevated. Satellite observation of the volcano are currently obscured by a low cloud deck.

(13) Other volcanic cloud information: Minor ash emissions observed in web camera images.
(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.
