Two Alaskan volcanoes that began minor eruptions weeks ago are showing their strongest seismic activity yet, emitting small amounts of lava and ash along with smoke plumes, the Alaska Volcano Observatory said Tuesday.
The observatory warned of more vigorous activity with the Pavlof and Veniaminof volcanoes, both on the Alaskan Peninsula -- though that will likely just mean more ash.
Pavlof, a snow-covered, cone-shaped mountain, has been erupting since early May. While its activity since then has waxed and waned, seismic activity increased since Tuesday morning and the volcano has started continuously shaking, said David Schneider, a geophysicist with the U.S. Geological Survey.
Some lava is flowing, and the volcano is spewing a cloud of steam and ash that has risen as high as 28,000 feet, said Schneider, at the observatory in Anchorage.
