Cascadia Rising Scenario

May 23rd, 2016 - Posted in Blog


Voice of Vashon is making plans to participate in an exercise to help Islanders prepare for a catastrophic earthquake.

During the drill and in the event of an actual emergency, tune into VoV Alert 1650AM, KVSH 101.9FM and the VoV app for smartphone.

The Cascadia Rising Earthquake Exercise Scenario
On June 7th, one of the worst natural disasters in U.S. history will (only hypothetically!) strike our region. It’s a practice exercise but it’s a vital one. We know the Cascadia fault ruptures every 300 to 500 years and the last one was in 1700, about 300 years ago.

The earthquake clock is ticking
Scientists who helped develop the scenario say coastal areas like Grays Harbor will be inundated when this magnitude 9.0 quake throws a 30 to 50 foot tsunami on unprotected shoreline. In Puget Sound, there would not be a tsunami but even at this distance from the coast, five minutes of severe shaking will injure hundreds.

Here on Vashon, ferry connections to the mainland would be broken, power would be out for weeks and many buildings would be damaged. We would quickly run out of almost everything from food to medical supplies and fuel. We will need mainland help, and lots of it. And that’s the main focus of practicing with the National Guard and King County Office of Emergency Management.
