Sure. It’s from glacial rebound. It causes tectonic motion and consequent quake activity. As much as the crust was laterally compressed by ice mass during the height of glaciation, it will have room to stretch out and depressurize. Estimated rise is about fifty meters in the Great Lakes region, from the recession of the Wisconsin glacier. You can figure out how much area that is by expanding the surface area of a sphere that same extent and finding the ratio of the difference. (101.5%) So a 200 mile stretch of surface has 203 miles of available space. The opposite is happening at the equator, as the soft jelly-bean Earth squishes about to maintain optimal roundness by gravity’s force.
I’m not sure about the results of it. We did have that New Madrid thing a while back, and then the SF Bay area was rocking for a full year after that.
Have you people never heard of tectonic plates? I have a service for eight in a nice floral pattern that I will donate to Des Moines…it might help them to feel less like they are stuck in a rut.

But this ‘shifting’ can’t possibly occur if THE EARTH IS FLAT! (also seen on the internet!)

I can think of a few cities I’d rather have in the stretch zones…

I am eagerly looking forward to this. Uh, should I also hold my breath?

Looks like a SyFy movie script.
