Modeling results indicate that the first tsunami wave is projected to arrive on land along the outer coast in 15 to 20 minutes following the earthquake. Inundation depths range from 20 to 60 feet (6–18.2 meters) on the outer coast, decreasing to generally less than 10 feet (3 meters) within Willapa Bay and Grays Harbor. Current velocities from the tsunami waves locally exceed 35 knots, presenting a significant navigational hazard to the maritime community. Tsunami wave inundation is expected to continue over 12 hours and remain hazardous to maritime operations for more than 24 hours after the earthquake.” https://washingtonstategeology.wordpress.com/2018/03/26/newly-published-southwest-washington-tsunami-inundation-hazard-maps/

“this model is an excellent tool for evacuation and recovery planning," the authors said.“

What evacuation? In 10-15 min?

If you've got a helicopter parked in your drive way and it's warmed up and ready to go... If you're at the base of a huge stone, hill and you've got a rocked sled on a track that heads to the top of the hill... Maybe if you've got one of those crazy rock climbing buggies that's all motor and tires...
