I moved to MT, what earthquake……?

You have the Yellowstone Caldera to worry about!

ETA: I see y’all covered that one.

I have a good generator (IE, sized to run my 140’ deep well pump), 50 gallons of gas in my boat tank, two big freezers full of food, 4 cords of wood, and I live in the woods with deer and turkey all over the place. Plus a year-round creek with cutthroat trout and crawdads. And finally, I’m rather heavily armed (don’t you dare call it an arsenal!) and am proficient with them.

It has occurred to me that a bad enough quake to really mess things up as far as, y’know, civilization in my AO, is almost certainly gonna collapse my well. So that sucks. But I do have the creek

You guys have me stressing again that I don’t have my machines earthquake-strapped a la California.

But seriously. Not an engineer here, but my big lathe weighs almost 5k pounds. It’s more or less next to a 2x4 framed wall. How the heck could I anchor 5k lbs to a 2x4 wall that keeps the damn thing from falling over in a BIG earthquake? Seems like any anchor would just rip out and really damage the (load bearing) wall in the process!

Suppose a guy could put a heavy steel plate across, what, 3 studs… have a forged lifting eye attached to the plate. Lathe strapped to that. Ugh. Not gonna happen.

I think it’s to better protect against liquefaction of the soil, as with movement everything turns to jello.

Here in the southern Valley we are on a giant sedimentary basin. My land sure is. Zero rocks, anywhere. Supposedly it’s all gonna liquify (temporarily) in a Big One.
