This polygon shapefile represents earthquake hazards data in San Luis Obispo County for 2013. This file was obtained 12/17/2013 by UCSB Library staff. It was originally available via http://lib.calpoly.edu/gis/browse.jsp?by=c&c=2.
The following metadata was provided by the data creators: A common type of ground failure associated with moderate and large earthquakes is liquefaction in which water-saturated fine-grained cohesionless sediments lose strength and may fail during strong ground shaking. Liquefaction susceptibility depends on the age and type of material, relative density of the material, and the depth to first (shallowest) water. Generally, younger sediments (especially latest Holocene that are less than 1,000 years old) such as loose fill, river channel, and flood plain deposits are more likely to liquefy than older Pleistocene terrace deposits. This map database depicts the relative liquefaction susceptibility for San Luis Obispo County
