*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

A great start!

The app does a fair job of mapping the danger regions. Good to know I'm just outside that major area for a tsunami. Hiwever, the app is NOT built for the iPad (SHAME) and it very ugly when used on one. The maps also redraw VERY slowly. I'm on a 20MEG DSL line, so it's not my end.

Good start. Let's see how it grows up.

Great Resource!

This app is great. The bugs mentioned in the few reviews must have been fixed as it works perfectly for me. I tested it out while camping at the coast in Nehalem Bay State Park and it worked flawlessly; specifically, the "entering and leaving tsunami hazard area" signs matched perfectly with the map as we were driving up and down the coast.

Regarding current location: go into settings>privacy>location services and select "on" for this app (scroll down to find it in the list).

I love the "center map to location" function in settings. It allows you to scroll/swipe ahead to plan your route, but then automatically snaps back to your current location.

Room for improvement may include the brochure links in Tabs. They should be updated to display the latest 2nd generation maps; the few that are currently available at least (e.g., Nehalem Bay).

Looking forward to future updates...

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.
