Abstract

Liquefaction of soils in response to earthquake shaking is a pressing issue in the state of California. Using Geographic Information Systems, Geological and lithology layers, along with criteria in order to separate out the data into four risk categories, a liquefaction risk assessment map was created for San Luis Obispo and Marin Counties. The accuracy of these maps was then assessed using liquefaction occurrences for San Luis Obispo County, and it was determined that while the map is somewhat accurate, in order to obtain a greater amount of accuracy and increase the usefulness of these maps, more data would need to be obtained, analyzed, and included in each of the County Map Layers.
