Peeking at the plumbing of one of the Aleutian's most-active volcanoes

(Carnegie Institution for Science) A new approach to analyzing seismic data reveals deep vertical zones of low seismic velocity in the plumbing system underlying Alaska's Cleveland volcano, one of the most-active of the more than 70 Aleutian volcanoes. Unlike typical seismic imaging experiments that deploy dozens of seismometers, this study used only eight.
