Alaska Volcano Pavlof Shoots Lava up Hundreds of Feet

Alaska’s remote Pavlof Volcano has been shooting lava hundreds of feet into the air, but its ash plume is thinning and is no longer making it dangerous for airplanes to fly nearby. Seismic tremors from the 8,262-foot volcano have been going up and down, but remain at a fairly high level. Scientists are not expecting the eruption to end anytime soon but so far it has not been explosive. There are mud flows, but no one close enough to be threatened. – ABC News
