COLD BAY -- One of Alaska's most active volcanoes sent a billowing white cloud almost 4 miles high late Thursday night, the biggest explosion since the 8,261-foot cone began vigorously erupting last month.
Pavlof Volcano, on the Alaska Peninsula about 600 miles southwest of Anchorage, put up a 20,000-foot plume about 9:30 p.m. Thursday, said Steve McNutt of the Alaska Volcano Observatory.
Pavlof stayed restive Friday and Saturday, blasting ash clouds 10,000 feet to 16,000 feet high, McNutt said.
"It just looked like a tall column rising, kind of like a cumulonimbus (cloud)," said Michael McLaurin, a meteorological technician with the National Weather Service in Cold Bay. "It rose about 18,000 or 20,000 feet and subsided, then built up again."
Clouds blocked the view on Saturday night.
Cold Bay and its 90 residents are about 40 miles southwest of the action.
Ash, a danger to aircraft, likely caused lightning Thursday, McNutt said.
An FAA spokeswoman said no flights were diverted Saturday. It wasn't immediately clear if Thursday's event interfered with air traffic.
The volcano set a personal record for explosions early Thursday morning -- 14 every minute, McNutt said. Seismic instruments began tracking activity at the volcano in 1973.
"I've never seen more than 10 a minute," said McNutt.
