FEMA prepares for Cascadia Subduction Zone 2016 Earthquake and Tsunami Exercise

The Cascadia subduction zone (also referred to as the Cascadia fault) is a subduction zone, a type of convergent plate boundary that stretches from northern Vancouver Island to northern California.

Federal Emergency Management Agency staff, and emergency responders from around the state met in Ocean Shores last week to get the public involved in a major exercise planned for 2016.
Chuck Wallace with the Grays Harbor County Emergency Management Agency said on Thursday it’s all to prepare the public and private sectors for a mock 9.0 Earthquake in the Cascadia Subduction Zone, a major fault line that runs through the county.

“How prepared are you today, to handle this? What do you believe will happen once this occures? And what kind of help do you need to get back in service? Because if this happens to our county, this impacts everybody.
Wallace said besides a tsunami, a CSZ earthquake will take out infrastructure “You’re going to feel the ground shake, you’re going to rattle and roll for a couple of minutes. You’re going to have some liquefaction where the ground becomes unstable, maybe water comes up through the ground [where] you normally wouldn’t think of. There’s some subsidence where they believe that the coastal area is going to drop about 4 to 6 feet and that will go probably almost to the county line before it levels out again.

The Exercise is from some of the same FEMA Region 10 crew that brought us The Great Washington Shake Out – registration for which just opened online by the way. Expect to hear more in the coming years about the Cascadia Subduction Zone (CSZ) 2016 Earthquake and Tsunami Exercise.
