|(5) Previous Color Code:||GREEN|
|(6) Source:||Alaska Volcano Observatory|
|(7) Notice Number:||2016/A24|
|(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:||Seismicity at Pavlof Volcano has increased in the past 24 hours, and minor steam emissions were observed in web camera images this morning. This unrest prompts AVO to raise the Aviation Color Code to YELLOW and the Volcano Alert Level to ADVISORY.
Pauses in eruptive activity lasting for weeks to months have occurred during past eruptive episodes of Pavlof Volcano, and a return to robust eruptive activity remains an ongoing possibility and could occur with little or no warning. AVO will continue to monitor the volcano closely.

|(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.|
