Scientists are getting an in-depth look inside the Sierra Negra volcano, the largest and most active on the Galapagos Islands, thanks to 15 seismometers buried beneath it. The data gathered are being used to create 3D images that show which lava sources are flowing into the volcano. "We'll now be able to more accurately measure the underground activity. That should help us better anticipate earthquakes and eruptions, and mitigate the hazards associated with them," said University of Rochester's Cynthia Ebinger, co-author of the study published in the Journal of Geophysical Research: Solid Earth.
