“Backwoods: Move away from cliffs and steep embankments where there might be falling debris or a landslide.”
LOL. Right. The earthquake will be over in a minute, maybe two or three tops. In an M9, you can’t stand up or walk. You aren’t going to get very far away from cliffs in that short time with the ground violently shaking.
It’s expected that an M9 earthquake will last six minutes.
“If you are driving, stop your vehicle.”
and pray the vehicle behind you stops!
Crawl like hell, I guess. If this struck in the winter, I'm guessing you'll see avalanches in the Cascades in areas where avalanches are not that common. That would be a big perturbance to any snow field on a slope and might break loose snow that would normally just stay put. Once something breaks loose, a cascading effect is unleashed (no pun intended).
FEMA thinks five minutes for the shake, and eighteen minutes from the P-wave until landfall, to bring the wash cycle into play. The survivors will have best results if they can make it to I-5. Any solid leads about earthquake spurred volcanic activity?
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!
>>Move away from cliffs
At level 9, you could find yourself standing “on a cliff” in an instant!
