An earthquake scenario tells the story of a defined earthquake and its consequences, to help communities understand the physical social, economic and environmental impacts of that earthquake.
Scenarios are useful tools for response planning, training and exercises; mitigation planning; recovery planning, training and exercises; and educational and awareness outreach.
The NEHRP Scenario Project (www.nehrpscenario.org) grew out of an Earthquake Scenario Planning Workshop in 2008 and the website contains a complete look at defining, creating, and implementing earthquake scenarios.
Many of the WSSPC states and communities have created their own scenarios, from the smallest to largest scales. These scenarios are linked below to their reports.
County of Hawai'i (2007)
This scenario looks at the island of Hawai'i and was the recipient of the 2007 Overall WSSPC Award in Excellence.
