The Pacific Northwest is facing a looming threat of a massive earthquake originating from the Cascadia Subduction Zone, prompting city officials, emergency managers, and researchers to prepare for cascading hazards such as fire and tsunami. They are focusing on examining the impact of these hazards on infrastructure systems and addressing challenges such as data availability, uncertainties in evaluations, and best practices for increasing urban community resilience.
The Pacific Northwest faces the looming threat of a massive 9.0 earthquake coming from the Cascadia Subduction Zone of the Juan de Fuca plate off the coast of Northern California, Oregon, Washington, and British Columbia. City officials, emergency managers, and researchers are preparing for this event by examining not only the earthquake itself, but also the cascading hazards that will follow it, such as fire and tsunami. Additionally, they must measure the effects of these hazards not just on the infrastructure systems they affect (e.g., water, power, transportation, communication, emergency services, etc.) but also how each system is affected by the failure of one or more of the others, or its dependency. The following paper discusses the effects of two cascading hazards-earthquake and fire-and the vulnerability of three infrastructure systems-building stock, water, and transportation-with a special focus on the needs of firefighters and other emergency services in the 12 h following a major seismic event. It then frames these methodologies in the context of a fine-grain case study of Seattle downtown and identifies three critical zones where mitigation measures would provide the most benefit. The discussion includes challenges in approaching such studies-the largest being available data, the uncertainties in making these evaluations, and general best practices for increased resilience in urban communities similar to the case study.
