Gov. Kate Brown, Oregon Office of Emergency Management Director Andrew Phelps, State Fire Marshal Jim Walker, and Interim Adjutant General, Oregon, Mike Stencel rolled out the latest version of the Cascadia Playbook Tuesday, Sept. 15 in Salem.
The Cascadia Playbook is an emergency management tool for a Cascadia Subduction Zone earthquake and tsunami and other significant disasters. The playbook supports various plans and efforts for the first 14-days of a catastrophic incident.
Every year, Oregon’s Office of Emergency Management (OEM) collects and analyzes threats, hazards and overall risk to communities throughout the state.
OEM works with local emergency managers to develop the Threat and Hazard Identification and Risk Assessment (THIRA). The THIRA provides data necessary to support statewide response and recovery planning efforts.
The threat with the highest consequence levels and potential to significantly effect people, property, the environment, and our economy is often used as a planning scenario to develop plans, training, and exercises. These activities build a stronger, more resilient community to be better prepared for our worst possible day.
About the Cascadia Playbook
Oregon’s greatest threat is a Cascadia Subduction Zone earthquake and tsunami resulting in significant loss of life, widespread injuries, and major property and critical infrastructure destruction. The Oregon Office of Emergency Management, per the Governor’s request, is kicking off a new initiative to synchronize efforts across the state in response to a Cascadia event and other significant disasters.
The Cascadia Playbook will be a cross-cutting emergency management tool for the State of Oregon that supports various existing plans and efforts for the first 14 days of a catastrophic incident.
The Cascadia threat
A Cascadia event is based on the threat of a catastrophic magnitude 9.0 Subduction Zone earthquake and resultant tsunami. Coastal communities will experience a devastating tsunami on top of severe ground shake (up to five minutes). Shaking intensity will be less in the I-5 Corridor and Southern Oregon, but older buildings and critical infrastructure may incur extensive damage.
• Ground shaking for 4-6 minutes causing massive critical infrastructure damage
• Liquefaction and landslides causing disruption of transportation routes
• Tsunami inundation to coastal areas with as little as 15 minutes warning
• Up to 25,000 fatalities resulting from combined effects of earthquake and tsunami
• Buildings destroyed or damaged, up to 10,000+ damaged structures
• Households destroyed or damaged, up to 10,000+ people in need of shelter
• $50+ billion in economic losses, not including critical infrastructure rebuild
