|(7) Notice Number:|
|(8) Volcano Location:||N 55 deg 25 min W 161 deg 53 min|
|(9) Area:||Alaska Peninsula|
|(10) Summit Elevation:||8261 ft (2518 m)|
|(11) Volcanic Activity Summary:||Over the past day low-frequency seismic tremor has been observed at Pavlof and web camera observations from this morning showed a vigorous steam plume from the summit. This represents an increase from background activity and we are increasing the the Aviation Color Code and Alert Level to YELLOW/ADVISORY.
This does not mean that an eruption is likely or imminent. However, past eruptions of Pavlof occurred with little or no warning.

|(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 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.|
