*TsunamiEvac-NW app developed by the Northwest Association of Networked Ocean Observing Systems (NANOOS)

TsunamiEvac-NW provides you an at-a-glance view of where the tsunami hazard zones are along the Oregon and Washington coast, and allows you to map whether your home, work, school, etc. is located in a tsunami evacuation zone or not. To help you develop and plan your own evacuation routes, TsunamiEvac-NW enables you to save your current position or points of interest via GPS or address look-up.

As an important tool in preparing for a potentially catastrophic local or distant tsunami event for residents or visitors to the Pacific Northwest coast, TsunamiEvac-NW also displays the locations of places that will be of critical importance prior to, during, and following a tsunami event, including schools, bridges, assembly areas, and various local government buildings.


o Up-to-date tsunami information published by Washington and Oregon state agencies and emergency managers, including evacuation zone maps, location of features of interest, and additional tsunami information for the public
o Access to the most current tsunami warning bulletins from the West Coast and Alaska Tsunami Warning Center
o Find a location by either address or GPS

Good app


If you go into setting and change the transparency to about 65% you can see all the map detail. I use hybrid to see where the affected businesses, healthcare facilities, schools, etc are. As a preparedness coordinator it allows me to show my colleagues where their sites are in relation to the tsunami zones. Nice tool.

Excellent app but doesn’t work with iOS11...


I used whenever I went to the Oregon or Washington coast to stay. It’s simple and excellent. (5 stars.)

Or was. Now it doesn’t work at all with iOS11. :( (-3 stars)

Hopefully the developer will be able to bring it up to date. Heck, I’d pay for that.

I'm glad to have it as a tool.


I live in a tsunami zone, it's nice to have this handy app.
