Workshops on subduction-zone science to reduce risk for communities

Release Date:

The USGS Pacific Coastal and Marine Science Center hosted two back-to-back subduction-zone workshops in Santa Cruz, California, from February 5–8, 2018.

Participants included USGS scientists from the Coastal and Marine Geology Program(CMGP), the Earthquake Hazards Program(EHP) the National Cooperative Geologic Mapping Program, and the Landslide Hazards Program, plus academic collaborators from Humboldt State University and Oregon State University. The first workshop, led by Janet Watt and Nathan Miller (CMGP), focused on developing a science strategy for a new Coastal and Marine Subduction Zone Marine Geohazards Project. The second, led by Joan Gomberg and Brian Sherrod (EHP), brought together researchers working to reduce uncertainty related to Cascadia megathrust earthquake recurrence. These collaborations are part of a USGS-wide effort to advance subduction-zone science and reduce risk from earthquakes, tsunamis, landslides, and volcanic eruptions.
