Pavlof still rumbling, but no more ash clouds

U.S. Geological Survey geologist Chris Waythomas says there’s still elevated seismicity, and the little explosions probably indicate lava fountaining at the summit.

Pavlof began erupting Sunday, sending up a massive ash cloud and disrupting some flights. Alaska Airlines resumed normal operations today.

Waythomas says clouds now surround the top of the 8,000-foot volcano. He says eruptions could stop abruptly or go on for months. Pavlof erupted intermittently for more than two years from April 1986 to August 1988.
