Volcanic Activity Summary: The elevated levels of seismic activity, apparent since about mid-May, have declined to background levels. Therefore we are lowering the Aviation Color Code and Alert Level to GREEN/NORMAL.
The volcano continues to emit a vapor plume that is occasionally visible in web camera views, and elevated surface temperatures continue to be observed occasionally at the summit crater in high-resolution satellite data. Such observations are common and reflect the steady emission of hot volcanic vapors from a near-vertically oriented vent.

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 March 2016 eruption, ash plumes as high as 40,000 feet above sea level were generated and the ash was tracked in satellite data as distant as eastern Canada. The nearest community, Cold Bay, is located 60 km (37 miles) to the southwest of Pavlof.
