I just had to highlight this. They got an intensity from it. Fur trappers? With satellite internet? I am amazed.
I once read a big study on earthquakes in stable continental zones. Just from the left-over stresses and slow rock processes, we can expect an m6 anywhere, once in a while. You can calculate the odds (very low) but shows that earthquakes end up in the weirdest places. Zones, such as Toronto and Oklahoma have odds a thousand times worse.
