Beat the Wave Technical Reports & Maps

If you are looking for "Beat the Wave" Tsunami Evacuation Route Maps, go here

When the next great Cascadia Subduction Zone earthquake and tsunami occur, coastal residents and visitors will have 10-30 minutes to reach safety. Evacuation on foot will be the only means possible. To be prepared, people need answers to questions:

  • What are the most efficient roads and trails to take to reach safety?
  • How fast will people have to travel to beat the wave to safety?
  • Will the earthquake cause bridges to become impassable or activate a landslide that blocks an escape route?
  • If safe evacuation isn't feasible, what other preparations can be made?

What do Beat the Wave technical maps look like?

The maps show the same green safety areas as on DOGAMI's tsunami evacuation maps, with the addition of arrows that indicate the most efficient routes. The quickest route may not be the obvious one, so it pays to study the map and practice your route. Colors on the maps show the speed that must be maintained from the starting point until safety is reached.
