Tsunami

There is a new option to escape a tsunami if you’re on the southwest coast of Washington when the Big One strikes. The Shoalwater Bay Indian Tribe on Friday dedicated a 50-foot tall evacuation tower in Tokeland, Washington. Tribal leaders and the Federal Emergency Management Agency said the new tsunami refuge platform should be an example and inspiration for other vulnerable coastal communities.

The January 15 volcanic eruption near Tonga was a stark reminder of the threats posed by tsunamis. That's long been a concern in the Pacific Northwest, where thousands of students go to school within reach of a large tsunami.

If you are on the Pacific Northwest Coast when the next Cascadia megaquake strikes — also known as "The Big One"— the standard advice is to run for higher ground as soon as the shaking stops. But in some low-lying places such as Ocean Shores and Long Beach, Washington, and Warrenton and Seaside, Oregon, the closest high ground could be a long walk away over buckled roads.

The state of Oregon is pushing the community hospitals along the Oregon Coast to improve their earthquake resilience. This comes after a state report predicted none of them would be able to sustain operations after the feared Big One -- a magnitude 9 offshore Cascadia earthquake and tsunami.

The 2011 earthquake and tsunami that ravaged Fukushima, Japan, also triggered tsunami warnings for our coastlines here in the Pacific Northwest. And while the resulting waves did not turn out to be catastrophic when they reached our local shores, those same forces delivered a wake-up call.

How's this for emergency preparedness? An elementary school located in the tsunami inundation zone in Cannon Beach, Oregon, has equipped every student with a personal disaster survival kit.

People visiting or living along the Pacific Northwest coast may be completely cut off after "The Big One" —the feared magnitude 9.0 Cascadia earthquake and tsunami. For that reason, the U.S. Navy has been scouting landing sites along the coast for disaster relief delivery by sea. The quake preparations ticked up a notch on Monday, with a practice delivery of supplies using two hulking Navy hovercrafts.

A legend about a great flood has been passed down through the centuries among the Klallam people on the north side of Washington's Olympic Peninsula. As re-told by Klallam elder Ed Sampson on a recording preserved by a University of North Texas linguist, the people noticed the fresh water turning salty -- a detail from which we infer a tsunami.

Ocean Shores, Washington, has no natural high ground inside its city limits. On Tuesday night, residents will meet with government and university experts to discuss whether to build a tsunami evacuation platform as in a few other Northwest coastal towns.

The worst case scenario for flooding from a tsunami along the Pacific Northwest coast just got even worse. Washington's Department of Natural Resources with federal help remapped the maximum tsunami threat from Grays Harbor down to the Columbia River mouth. Chief Hazard Geologist Corina Forson says updated science about the offshore Cascadia fault zone produces a bigger surge.
