Let’s all hope that remains a WAG.
(Especially since I live just a bit north of Yellowstone, and anything that shakes Cascadia would probably start something over here as well.)
“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.”
This. I have family up there. Sure hope the big one doesn’t hit.
