Loma Prieta, California, Earthquake October 17, 1989. Watsonville area. Support column of the bridge across Struve Slough on Highway 1. Enlargement of the hole where the support enters the ground is an effect of lateral shaking. This caused the concrete to break up where the column joined the bridge and was instrumental in the roadbed collapse. 1989. Slide XIV-14, U.S. Geological Survey Open-File Report 90-547.
Loma Prieta, California, Earthquake October 17, 1989. Crack system near Summit Road, half a mile southeast of Highway 17. As it crosses Summit Road, the crack trends nearly north, rather than northwest, and displays a large component of left-lateral displacement. In general, the upthrown block is on the downhill side of this crack. The swale along the crack on the northeast side of Summit Road ridge in this area suggests similar displacement may have occurred in the past. Figure 10-C, U.S. Geological Survey Circular 1045.

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.
