Inventory of Lifelines in the Cajon Pass, California (FEMA 225)


FEMA This report provides an inventory of the major lifeline systems in the Cajon Pass. The report describes the earthquake and geologic analysis tools available to identify and define the level of seismic risk to those lifelines. The vulnerabilities occurring from the siting of multiple lifeline systems in confined and at risk areas due to their interactions from natural and manmade disasters are evaluated. Potential mitigation techniques for communication lifelines, electrical power lifelines, fuel pipelines, and transportation lifelines are identified. Detailed maps indicate lifeline locations. The report also discusses seismic hazards and predictive models for evaluating the damage potentials associated with the various seismic hazards.
