HayWired: Focusing on the Fault

Today, on the 112th anniversary of the 1906 Great San Francisco Earthquake, Cal OES joined experts and representatives from many disciplines and agencies on the UC Berkeley campus to discuss the HayWired Scenario, a regional and statewide earthquake preparedness initiative that aims to shift behavior about earthquakes, bolster awareness, and ensure that everyone is better prepared.

The HayWired Scenario is a hypothetical earthquake sequence that is being used to better understand hazards for the San Francisco Bay region during and after an earthquake of magnitude 7 on the Hayward Fault. A large Hayward Fault earthquake will produce strong ground shaking, permanent displacement of the Earth’s surface, landslides, liquefaction (soils becoming liquid-like during shaking), and subsequent fault slip, known as afterslip, as well as aftershocks.

The next large Hayward Fault earthquake is anticipated to affect thousands of structures and disrupt the lives of millions of people. The HayWired scenario examines earthquake hazards to help provide the crucial scientific information that the San Francisco Bay region can use to prepare for the next large earthquake.

The scenario is used to explore how the region will be affected, what information is needed, and what decisions to make before and after an earthquake. Engagement from partnering agencies, scientists, and the community provides even greater realism ultimately providing an even clearer picture of our common threat and what we can do about it.

“This is a call to action day. Everyone should be asking themselves what more can I do,” said Cal OES Deputy Director of Planning, Preparedness, and Prevention Christina Curry.

HayWired is just one of the programs Cal OES participates to promote planning, preparedness, hazard mitigation, and reduce risks among vulnerable areas of California. Since 77 % of country’s earthquake risk is in California, Cal OES has a large mission and in addition to HayWired, Cal OES is focused on reducing risk through several programs.

In 2013, Governor Edmund G Brown Jr. signed a bill directing Cal OES to implement an Earthquake Early Warning System (EEW) in California. ShakeAlert is what will evolve into the EEW system and a final system will probably look very much like this prototype. Currently, sensors are being placed throughout the state.

On October 18 at 10:18 a.m., millions of Californians will once again participate in the Great ShakeOut, the statewide earthquake drill.  Since 2008, ShakeOut has expanded from California to include more than 20 regions, including multiple states and counties.

There is also the Earthquake Brace + Bolt Program, which designed to help homeowners in ZIP codes that face the highest risk of earthquake damage to homes, based on local geological hazards combined with the vulnerability due to home construction type.

Unless we take action today, there will be major losses of life and property. These programs help raise awareness as well as help Californians prepare for the big earthquakes in our future.
