* 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

Version 2.3.1

This version changes the color of the bulletin text to white for warning statements making it easier to read against the red background.

One fix could make this so much better

I live on the edge of an inundation zone, so I was delighted when this app was released. It's the kind of app that could really save lives in my community and so many others, and I'm incredibly grateful for the science and expertise behind it.

Here is something that would be a game changing improvement on the current build: how about sending an audible notification ONLY when the alert does not specify that there is no threat? That way, I don't have to chooose between getting a potentially life-saving alert and getting wakened on the regular by non-threatening events. I am not sure if there is an upside to waking me up only to read that something does not pose a threat. It seems like the downside - that users silence the notificications altogether at night - defeats the purpose of the app.

Thanks for considering my suggestion, and thanks again for working on this important project!

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.

Very useful

My local map even shows the creeks correctly on and near our property. It is a wetland and they have changed over the years - this one is up to date. It shows a tsunami from a local earthquake going much higher than we thought it would, up the creeks to over 70’ elevation! This has changed where we need to plan to go to get out of the inundation zone.

A feature I like is being able to enter an address or your current location as a marker on the map. A pop up will tell you which zone you are in. You can edit labels for the markers. I wish I could find a way to delete markers I put in by accidentally touching the screen, though. I rated it 5 stars despite this because it easy to use, and provides so much trustworthy information which could save lives and suffering.

Hi miz.mdk ,

In the list of markers you can swipe a marker to the left to delete it.
