This is only a drill. This scenario exercise was developed by USGS and CGS, and will begin at 9:00 am PT on May 11, 2016.

This exercise will use the “Haywired” scenario, a M7 earthquake on the Hayward fault.  Geology field teams will be deployed to locations on the Hayward fault to make observations of fault offset and surface rupture.  Fault creep features will stand in for surface rupture for the purpose of this exercise. Suggested locations include downtown Hayward and Fremont.
