93. This house was dislodged from its foundation and moved 0.75 meters (2.5 feet) from the cement stairway in downtown Watsonville. [J.K. Nakata, U.S. Geological Survey]
Note that the building has moved diagonally, a typical motion when all four shear walls of a structure collapse. For this to occur the usual failure mode is for the corners to disassemble, and good design or retrofitting pays special attention to the corners of such structures.
