[Ed. – Would love to use my own photos of Great Sitkin for illustration, but it would take forever to dig them out.]
Three remote Alaska volcanoes are in various states of eruption, one producing lava and the other two blowing steam and ash. …
Webcams on Thursday clearly showed episodic low-level ash emissions from Pavlof Volcano, prompting the observatory to raise the volcano’s threat level from yellow, or exhibiting signs of unrest, to orange, indicating an eruption is underway with minor volcanic ash emissions.
Ash clouds were rising just above the volcano’s 8,261-foot (2,518-meter) summit, drifting about 6 miles (9.7 kilometers) to the south before dissipating, [geologist Chris] Waythomas said.
Pavlov is a “very sneaky volcano,” Waythomas said. “It can get going without much warning.” …
The observatory on Thursday received reports from people in the community of Adak of a lava fountain at the summit of the Great Sitkin volcano. The reports were later confirmed by webcam.
“The fact that they just happen to walk outside and see it was really great,” Waythomas said.
