Loma Prieta, California, Earthquake October 17, 1989. Watsonville area. Ground shaking triggered liquefaction in a subsurface layer of sand, producing differential lateral and vertical movement in an overlying carapace of unliquified sand and silt, which moved from right to left towards the Pajaro River. This mode of ground failure is termed "lateral spreading" and is a principal architect of liquefaction-related earthquake damage. Slide XIV-4, U.S. Geological Survey Open-File Report 90-547.
