The Haywired Scenario Exercise Toolkit is now available!

Learn more below about the Scenario and the purpose and structure of the new Toolkit.

The Toolkit is designed for use by businesses, government agencies, non-profits, community groups, and other organizations to plan, lead, and learn from discussion-based exercises. It was created through the collaborative efforts of the California Resiliency Alliance, Earthquake Country Alliance, and USGS, with input from other partners.

If you are interested in being notified of upcoming activities and Toolkit updates, please complete the interest form at the bottom of the page.

Overview of the USGS HayWired Earthquake Scenario:

The three volumes of the HayWired Earthquake Scenario Report explore the physical, technological, and societal impacts of a hypothetical magnitude-7.0 earthquake on the Hayward Fault (and its aftershocks). Each volume is available at here along with related resources. You can also download them here:

• The HayWired Earthquake Scenario—Earthquake Hazards (Vol. 1, Chapters A-H) (55 MB)
• The HayWired Earthquake Scenario—Engineering Implications (Vol. 2, Chapters I-Q) (200 MB)
• The HayWired Earthquake Scenario—Societal Consequences (Vol. 3, Chapters R-W) (150 MB)

   Additional HayWired Earthquake Scenario educational resources:

• A multimedia HayWired overview movie
• Hayward fault earthquake shaking simulations
• An interactive online storymap that uses various types of multimedia content to explain and illustrate the HayWired earthquake hazards and includes an animation of the strongest shaking throughout the earthquake sequence.
• A geonarrative with a photo and corresponding narrative text of what to expect during and after an earthquake in an urban setting.

Purpose of the HayWired Scenario Exercise Toolkit:

• The impacts described in the HayWired Earthquake Scenario readily allow for the creation of plausible exercises, even for people with little or no exercise experience.
• The Toolkit links to information in the scenario for use in discussion-based exercises by any organization (private sector, government agency, or non-profit) or network.
• While primarily focused on the expected losses and outcomes of an earthquake on the Hayward fault, the Toolkit can be adapted for other scenarios, even in other regions, as the issues and exercise ideas included are likely to be similar.
• These exercises may improve resilience by identifying vulnerabilities and exploring different ideas for addressing disruptions and challenges, including those not caused by an earthquake.
