Liquefaction in Subsurface Layer of Sand

Image: Liquefaction in Subsurface Layer of Sand

Detailed Description

Ground shaking triggered liquefaction in a subsurface layer of sand, producing differential lateral and vertical movement in a overlying carapace of unliquified sand and silt, which moved from right to left toward the Pajaro River. This mode of ground failure, termed "lateral spreading," is a principal cause of liquefaction-related earthquake damage.
