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.
