Visitors to the Oregon coast - Know before you go!

Tsunamis are generated when geologic events cause large, rapid movements in the sea floor that displace the water column above. These destructive waves can be caused by coastal or submarine landslides or volcanism, but they are most commonly caused by large submarine earthquakes. The Pacific Coast is at risk both from locally and distantly generated tsunamis.

For the Hospitality Industry: Oregon Coast Visitor Tsunami Awareness

The purpose of the Oregon Coast Visitor Tsunami Awareness project is 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. It is being funded by the National Tsunami Hazard Mitigation Program (NTHMP), a part of the National Oceanographic and Atmospheric Administration (NOAA).

Tsunami Evacuation Wayfinding

One of the best ways to survive is to be able to get out of the tsunami inundation zone quickly. In order to do this, it is imperative that escape routes are clearly marked no matter the time of day or weather conditions. As Oregon has been a leader in tsunami hazard mitigation, we are continuing this tradition with this “Up and Out” wayfinding project.
The Oregon Office of Emergency Management is very happy to partner with the Portland Urban Architecture Research Laboratory to seek creative solutions that will save lives during a tsunami event.  Their work in other disaster prone areas, especially in hard hit Japan, makes them an excellent choice for this project.
It is hoped that this is the first phase in creating a much safer Oregon by putting in place wayfinding systems that will help our residents and visitors escape to safety. This report can be used by communities to evaluate and re-invigorate how they create routes to safety.

Distant Tsunami Response

Oregon Emergency Management is established a Distant Tsunami Response Working Group to create a standardized response to a distant tsunami on the Oregon coast.
The goal of this group was to look at current processes and produce recommendations for state agencies and local communities to better react to a distant tsunami warning, watch or advisory.
