Detailed Description

Blue arrows indicate contraction across the upper and middle rift zone as magma withdrew from this area and moved down the rift zone beginning on April 30, 2018. Black arrows indicate expansion across the rift zone as magma intruded into the LERZ; the area stopped widening on about May 18. Also, beginning in early May, magma began moving from the summit reservoir into the East Rift Zone. Data sources used in this modeling are from the U.S. Geological Survey, University of Hawai'i, NASA, Jet Propulsion Laboratory, Japan Aerospace Exploration Agency, and the European Space Agency.
