Fire following Earthquake Risk Assessment: The City of Los Angeles’ Efforts toward Water System Seismic Resilience and Sustainability
As part of the Los Angeles water system implementing a resilience program, a planning-level study was undertaken to quantify post-earthquake firefighting water demands, for which a model was developed to quantify ignitions and firefighting water requirements for five earthquake scenarios. The model estimated the building stock, earthquake ground motions, post-earthquake ignitions, fire department operations, available firefighting water supply, fire spread, and water required per fire. Model results were validated against the 1994 Northridge earthquake. Three of the five scenarios are very severe events, causing over 100 ignitions each, with two events—Puente Hills Mw 7.0 and Santa Monica Mw 6.8 probably exceeding the fire department’s capacity. These results are useful for assessing the water system’s ability to meet the fire flow demands in a post-earthquake damaged state. Further hydraulic assessments will help identify and prioritize system improvements.
