Summary
| Description |
English: Original caption: Loma Prieta, California, Earthquake October 17, 1989. Watsonville area. This house was dislodged and moved 0.75 meter (2.5 feet) from the cement stairway in downtown Watsonville. Slide XIV-10, U.S. Geological Survey Open- File Report 90-547.
Comments: Image shows low cripple wall collapse and detachment of structure from concrete stairway. 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. |
