CREW Cascadia Subduction Earthquake

This Scenario was prepared by the Cascadia Region Earthquake Workgroup (CREW), a partnership of the private and public sectors, created to help the Cascadia area prepare for earthquakes. The workgroup knows that magnitude (M) 8 to 9 earthquakes have occurred in this region and will occur again, on average, every 500 years. This report is the result of many years of research, discussion, and debate, and is based on computer modeling as well as other research about earthquakes in the region. The scenario was developed to help government agencies, businesses, and families understand the potential effects of a subduction earthquake.
