It's hard to even imagine this kind of precision. I wonder what would happen if a gravitational wave would hit us that would cause displacement on the same order of magnitude an earthquake causes. Would this rip the planet apart or would just nothing happen?
To experience that, you’d need to be so close to some very extreme event (neutron star merger for example) that you’d already be in desperate trouble, and a planet wouldn’t hold together. You could hypothetically experience something less impressive than an earthquake, but less impressive than having your atoms strung out like spaghetti.
