They have estimated the Cascadia quake lasted about 5 minutes. But yeah - you’re not going to be able to move very well with all that shaking going on!
I think I’m prepared for it (live near Seattle), but probably not as well as I think that I am!
I just moved back from Oak Harbor on Whidbey Island. I was working over there during the week the last few years but my home is in eastern Washington. I was always thinking about the big one and being stuck over there. All of the tsunami models showed Oak harbor to be safe, but Deception Pass Bridge was a definite goner, along with our water supply main which came from Anacortes that crossed under bridge as well. They don’t have enough water supply on the island to make up that loss. We figured the Navy would pull up an aircraft carrier with a desalinization plant because of the Navel Air Station located there.
