Pavlof 2017/6
Start: June 7, 2017 [1]
Stop: August 30, 2017 [1]
Event Type: Not an eruption
Description: The Aviation Color Code for Pavlof Volcano was raised to YELLOW on Wednesday, June 7 following an increase in low-frequency seismic activity and a pilot report indicating a possible ash cloud to 4000 ft asl. Active degassing from the summit was observed in web camera images and by local observers in Cold Bay yesterday and this morning. Infrasound data from local instruments on Pavlof and a more distant network in Sand Point show no evidence of significant explosive activity during the past week. Seismic activity has been at background levels since Thursday, June 8. Precursory activity leading up to previous explosive eruptions at Pavlof have been subtle and while some episodes of increased seismic activity have preceded eruptive episodes other increases have died back down without explosive activity.
Weakly elevated surface temperatures and vapor plumes continued to be observed at Pavlof, but declined through June, July, and August. On August 30, 2017, citing normal, background levels of activity at Pavlof, AVO lowered the Aviation Color Code and Volcano Alert Level to GREEN/NORMAL.
