Eruptions from Pavlof Volcano continued on Wednesday after rumbling to life earlier in the week. The 8,261-foot peak on the Alaska Peninsula awoke Monday morning, kicking off a "low-level eruption of lava," according to the Alaska Volcano Observatory (AVO). Sitting about 30 miles northeast of the community of King Cove, Pavlof is a frequently-active volcano that last erupted in 2007. The volcano's rumbling has strengthened this week. At about noon Tuesday, satellite images showed a lava flow had coursed a third of a mile down the northern side of the volcano.
By late Tuesday, an ash plume extended 15,000 feet above sea level, moving downwind to the northeast for up to 100 miles before dispersing. The National Weather Service issued a "Significant Meterological Event" warning, called a SIGMET, to alert pilots of hazardous conditions in the area. Pavlof continued to rumble Wednesday, with one pilot reporting a dark ash cloud reaching 20,000 feet. Residents of Cold Bay, located 37 miles southwest of the volcano, observed incandescent glow at the summit during the night. Pilot reports and photographs from yesterday afternoon indicate that the lava flow extending down the northwest flank is still active and has generated debris-laden flow deposits, presumably from interaction of hot lava with the snow and ice on the flank.
