SPA’s Charles Scawthorn spoke on November 30, 2020 to the Port of San Francisco. More than 60 people attended. He provided an overview of San Francisco’s risk from fire following earthquake with a focus on the port and the role it could play in reducing this risk. The port plays a crucial role in San Francisco’s economy. Fire risk for the port is very significant. For most of its history, the port has sustained a major pier fire about once a decade. Most recently, a five-alarm fire at Pier 45 destroyed the crab fishing fleet’s fishing gear, crippling this year’s catch. Scawthorn suggested two key ways the port could help to lower fire following earthquake risk: (1) As part of the port’s multi-billion dollar seawall renovation, it could include a utilidor (utility corridor), which could provide a low-impact reliable utility service for waterfront development, including reliable fire protection; and (2) Develop a distributed series of solar-powered fire protection pumps. The pumps could serve port facility sprinklers (surprisingly, a significant portion of the port’s facilities are not sprinkled) and contribute significantly to the city’s emergency firefighting water supply.

An earthquake near Vancouver, British Columbia, could ignite hundreds of fires and cause $10 billion (Canadian dollars) of property damage. This amount is over and above shaking damage. So finds our Dr. Charles Scawthorn in a new study sponsored and published by the Institute for Catastrophic Loss Reduction (ICLR). (Links here for video, executive summary, and full report.)
These earthquake are inevitable. Scawthorn considered five earthquakes. One was an expected magnitude-9 earthquake on the Cascadia Subduction Zone. That earthquake and several closer, smaller ones, are inevitable. Most of the buildings shown here will exist and be full of people when, not if, these earthquakes occur. Insurers will bear most of the property losses. If the risk is not reduced before then, a leading global reinsurer thinks the losses would bankrupt some insurers. The insurance bankruptcies could lead to financial contagion.
How to reduce the risk. The earthquakes are inevitable. The losses and bankruptcies are not. SPA and ICLR are helping firefighters, City of Vancouver officials, provincial officials, engineers, and others understand three ways to reduce the damage and suffering. They are:
- Seismic gas shutoff valves. Require that all gas meters have seismic gas shutoff valves.
- Portable water supply systems. Integrate portable water supply systems in every fire department.
- Secondary water supply. Add tanks with a 30-minute supply of firefighting water to all high-rise buildings.
