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.

HayWired Earthquake Scenario—We Can Outsmart Disaster”.

This “geonarrative”, which includes interactive maps, videos, and other
media, examines the earthquake hazards in the HayWired scenario’s 11-county
HayWired Scenario ShakeMap
This scenario ShakeMap shows ground shaking caused by a hypothetical M7.0
earthquake on the Hayward Fault. The mainshock (star) is beneath the City of
Oakland and causes the Hayward Fault to rupture along about 52 miles
of its length (thick black line). White lines depict other major faults in

The 150th Anniversary of the Damaging 1868 Hayward Earthquake: Why It
Matters and How We Can Prepare for Its Repeat
Watch Tom Brocher, USGS Research Geophysicist, deliver the USGS Evening Public
Lecture. This talk was recorded on September 27, 2018.
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.
