The HayWired Earthquake Scenario
The USGS and its partners developed the HayWired scenario as a tool to
enable further actions such as seismic upgrades and retrofits that can
change the outcome when the next major earthquake strikes.

This “geonarrative”, which includes interactive maps, videos, and other
media, examines the earthquake hazards in the HayWired scenario’s 11-county
Hayward Fault Scenario Earthquake Animations
Computer simulations of earthquake shaking on the Hayward
and Rodgers Creek faults.
Blue Dot Podcast: The Hayward Fault
Host Dave Schlom is joined by USGS Geophysicist Ken Hudnut as they
interview two leading experts on the Hayward Fault: USGS scientists
David Schwartz and Tom Brocher. It’s a fascinating and frightening
discussion of the “ticking seismic time bomb” beneath the East Bay.
Missing Link Between the Hayward and Rodgers Creek Faults
The next major earthquake to strike the San Francisco Bay Area will most
likely result from rupture of the Hayward or Rodgers Creek faults. New
models show that these faults are directly connected at the surface, which
enables simultaneous rupture of the Hayward and Rodgers Creek faults, a
scenario that could result in a major earthquake.
Direct Connection Between the Hayward and Calaveras Faults Uncovered
A new model suggests the Hayward and Calaveras Faults should be treated
as a single system with the potential for generating larger earthquakes in
the San Francisco Bay Area.
