New modeling by the University of Washington of the impacts of a major Cascadia earthquake offers a less dire picture of the aftermath of the so-called "Big One" — specifically when it comes to highway bridges.

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.

A huge dress rehearsal for regional earthquake disaster relief was supposed to happen next week until the ongoing pandemic forced its cancellation. The scrubbed Cascadia Rising exercise would have involved more than 22,000 participants – chiefly U.S. soldiers, sailors and airmen as well as state, local and tribal emergency planners. Some smaller drills are going ahead this weekend and next featuring civilian volunteers who will demonstrate unusual ways aid may get to Pacific Northwest earthquake survivors.

Close to 200 federal, state and tribal emergency preparedness planners gathered around a giant map of the Pacific Northwest this week to rehearse and critique the federal response plan for "The Big One." The three-day Cascadia earthquake discussion exercise partially replaced a much bigger planned dress rehearsal that was canceled due to the coronavirus pandemic.

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 has set an ambitious goal to prepare more families in earthquake country to be "two weeks ready" after a disaster. Washington's emergency management agency is also seeking more funding to prepare people in a similar way.

Tens of thousands of public school students in Washington state returned to classes this month in school buildings judged to be at risk of collapse in a strong earthquake. A new report to the state Legislature prepared by state geologists and a structural engineering firm gave the lowest possible seismic safety rating to more than 90 percent of the school buildings assessed in a selective statewide survey.

Residents living on the West Coast don't know when the next earthquake will hit. But a new expansion of the U.S. earthquake early warning system gives 50 million people in California, Oregon — and now Washington — seconds to quickly get to safety whenever the next one hits.
