* Oregon and Washington tsunami evacuation zone maps developed by the Oregon Department of Geology and Mineral Industries (DOGAMI) and the Washington Department of Natural Resources (WADNR)
*NVS Tsunami app developed by the Northwest Association of Networked Ocean Observing Systems (NANOOS)

NVS Tsunami 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, NVS Tsunami 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, NVS Tsunami 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

What’s New

Great PNW tsunami alerting and hazard map app

This is the only app that provides you with the most up to date tsunami hazard areas for OR and WA. Great for people who live, work, or play on the coast.

SUPER COOL new feature also sends you tsunami alert texts. Nani’s got me the tsunami alert 4 minutes faster than other mechanisms I’m signed up for. This app is also more easily accessible to more users than the national weather service one but provides the same authoritative information. Great app!

OR, WA Tsunami hazard zones on your phone

Everyone living along or visiting the Oregon or Washington coast should have this app. It shows tsunami inundation zones, evacuation routes, high ground, and assembly areas. I use it every visit to the coast to check local inundation zones and fastest route to high ground. Use it to plan your family’s evacuation strategy and safe meeting place. Note that roads will likely be jammed with cars and the fastest route will likely be on foot.

A complete re-development of the original app. More responsive and more capabilities. The app allows the user to locate themselves anywhere along the Oregon/Washington coast and determine where they are relative to mapped tsunami evacuation zones. Great job!
