The Haywired Scenario Exercise Toolkit will be available soon!

This page is being developed.  Please complete the interest form below to be notified about the Toolkit and related activities.



The USGS HayWired Earthquake Scenario explores the physical, technological, and societal impacts of a hypothetical magnitude-7.0 earthquake on the Hayward Fault (and its aftershocks).

Educational resources include:

  • 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 Toolkit

  • The impacts described in the HayWired 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.
  • The toolkit can be adapted for use elsewhere as the issues and exercise ideas included are likely to be similar in after major earthquakes in other regions
  • These exercises may improve resilience by identifying vulnerabilities and exploring different ideas for addressing disruptions and challenges.
