Nothing here. We're on top on 10 or 20 feet of clay from a big glacial lake during the last Ice Age. It's murder to plant in and worse to put up a fence in, but doesn't conduct an earthquake shock at all. We didn't feel 'the big one' that damaged the Washington Monument, either.
FWIW I slept through it.
the "big ones" cover 1/2 of the US when they happen over there. (New Madrid).
