I’m 30 mi. south of Seattle. Felt nothing.

That sucker was close to the Cascadia Subduction Zone. Too close. I hope to God this wasn’t a foreshock. That sucker lets go, and you can count on massive damage throughout Western Washington.

(Those longshoremen in Longview would have to worry about their contracts if a tsunami washes their thug butts out to sea.)

Anyone know what percentage of the time quakes like this are foreshocks.

They were just talking about that.

Actually, it kinda depends.

At the places that the fault run N/S off the coast of Washington state, it’s about 50 miles out from the coast.

And most people who live in Western Washington live on the east side of Puget sound, the Olympic peninsula adds another 60 miles or so distance to the main fault.

So being 100 miles away from the fault is probably a good thing. Whether there was huge damage here would probably depend on how big the quake was, how much linear length of the fault ruptured, and what was the specific ground motions involved.

I have seen a map of the Pacific Ring of Fire that showed that the only location on that ring not to have had a Mega quake in the last 50 years is the Cascadia Subduction Zone. The last one was in 1700 which was between a 9 and 10 on the scale.
