Collocation Impacts on the Vulnerability of Lifelines during Earthquakes with Applications to the Cajon Pass, California

This report presents a new analysis method to identify the increase in the seismic vulnerability of individual lifeline systems (communication systems, electric power systems, fuel pipelines, and transportation lifeline) due to their proximity to other lifelines in the Cajon Pass. The method calculates a parameter that can be used to adjust the damage state values for shaking as determined by the ATC 13 damage probability matrices. The primary objective of the study was to determine how the time to restore full service would be affected by the collocation of several types of lifelines in the same congested corridor. The new method is applied to the Cajon Pass lifelines. The design program, AutoCAD, is used to develop overlays of the lifeline routes with seismic and geologic information presented in the inventory report (FEMA 225).
