ANCHORAGE — An Alaska volcano kept pumping out new ash Tuesday that could threaten aircraft, but it came in smaller amounts at lower heights, according to the Alaska Volcano Observatory.
Pavlof Volcano, 625 miles southwest of Anchorage on the Alaska Peninsula, erupted Sunday. The initial eruption continued for about 17 hours and put out an ash cloud that reached 37,000 feet.
The plume blew northeast and by Tuesday had reached Canada, but Dave Schneider, a U.S. Geological Survey geophysicist at the observatory, said activity had calmed from the continuous eruptive phase.
