Yes, a 5.1 quake 20 miles away will rock your world! (Speaking from recent experience) 🙂
The ranch here is built on a flat slab on gravel over lava rock. It has endured 45 years of some pretty nasty ‘shakers’ because the whole slab ‘floats’ together without ripping the house apart. Many homes here are build above ground on post & pier settings, effectively giving the house ‘legs’ to stand on. These frequently ‘walk’ off their foundation piers and tear the house apart in a good shaker.
