Earthquakes and the tsunamis that can result from them are inevitable in the Pacific Northwest -- but the damage is not.
How prepared is your community?
This report evaluates the difficulty of pedestrian evacuation of Seaside and Gearhart, Oregon, in the event of a local tsunami generated by an earthquake on the Cascadia subduction zone (CSZ). The map plates depict minimum evacuation speed needed to stay ahead of the wave for three levels of increasing evacuation difficulty: 1) all bridges intact, 5-minute delay from start of earthquake before starting evacuation, 2) only retrofitted bridges intact, 5-minute delay, and 3) only retrofitted bridges intact, 10-minute delay.
Up and Out: Oregon Tsunami Wayfinding Research Project
Tsunami readiness consists of preparation, evacuation, and response. Preparation can be made now through increased awareness and education. Evacuation is the time when individual and community preparation is put into operation and where survivability will be decided in a matter of minutes. Evacuation success depends on how prepared individuals and communities are and is guided by ongoing public outreach including the clarity of routes, signs, and symbols that help people evacuate as quickly as possible. In these reports, through a partnership between Oregon Emergency Management (OEM) and the Portland Urban Architecture Research Laboratory (PUARL), innovative wayfinding schemes are examined to help coastal communities build community resilience before, during, and after a catastrophic tsunami event.
The South Clatsop County Resilience Guide, prepared by the Oregon Partnership for Disaster Resilience, provides information about community resilience and a structured approach that can be used by communities to improve resilience to natural hazards. The guidelines include resilience assessments and goals. Although the guidelines were developed in partnership with north coast communities, they are a good source of information for use by any community considering planning for community resilience.
The Land Use Guide, prepared by the Oregon Department of Land Conservation and Development (DLCD), provides coastal communities examples of comprehensive plan language and development code provisions that can serve to help communities reduce their risk to tsunami hazards. These examples are intended to provide general guidance allowing communities to tailor land use policies and regulations appropriate to their individual circumstances.
Community Tsunami Preparedness is now live on the MetEd website and available in the FEMA EMI Independent Course catalog as IS-326.
This module is designed to help emergency managers prepare their communities for tsunamis. Lessons include basic tsunami science, hazards produced by tsunamis, the tsunami warning system, the importance of public education activities, and how to craft good emergency messages and develop tsunami response plans. The module also contains links to extensive Reference and Resources sections. Login required but registration is free.
Funded by the National Tsunami Hazard Mitigation Program (NTHMP) and hosted on the Oregon OEM site, the the Oregon Coast Visitor Tsunami Awareness project exists to improve the visitor’s awareness of the tsunami hazards and to support the hospitality industry on the Oregon coast in becoming more prepared for tsunami events.
