Cleveland Volcano has blown its top again. An explosion shook the restless Aleutian volcano at around 7:00 Wednesday night. There’s no monitoring network on the volcano itself, but distant seismic stations and sound arrays picked up the blast.
In a release, scientists at the Alaska Volcano Observatory said they suspect it was a small explosion, similar in size and magnitude to the one that happened in December. That eruption destroyed a lava dome that had been forming in Cleveland’s crater for several months. Gases often collect underneath the domes, causing pressure to build until it explodes. A new dome had been forming in Cleveland’s crater since the December event.
