This is the part that gets me. It seems so unbelievable. I had an interesting experience with vibration a few orders of magnitude larger once. We are located on sedimentary stuff in a river delta. Next door was a container yard and once they dropped a full 40 tonner off the top of a seven high stack. My VF0 actually bounced off the floor.
