Slow earthquakes occur continuously in the Alaska-Aleutian subduction zone 07/21/2017 09:46 AM EDT Seismologists at the University of California, Riverside, studying earthquakes in the seismically and volcanically active Alaska-Aleutian subduction zone have found that "slow earthquakes" are occurring continuously, and could encourage damaging earthquakes. Slow earthquakes are quiet, can be as large as magnitude 7, and last days to years. Taking place mainly at the boundary between tectonic plates, they happen so slowly that people don't feel them.
