Seismic Stations Pick Up Cleveland Blast

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.
