For years, wildfire-resilient home and neighborhood design has been a niche consideration for many California homeowners. January’s Los Angeles firestorms have made it feel more like an urgent necessity.
At 05:12 AM Pacific Standard Time on Wednesday, April 18, 1906, the coast of Northern California was struck by a major earthquake with an estimated moment magnitude of 7.9 and a maximum Mercalli intensity of XI (Extreme). High-intensity shaking was felt from Eureka on the North Coast to the Salinas Valley, an agricultural region to the south of the San Francisco Bay Area. Devastating fires soon broke out in San Francisco and lasted for several days. More than 3,000 people died and over 80% of the city was destroyed. The event is remembered as the deadliest earthquake in the history of the United States. The death toll remains the greatest loss of life from a natural disaster in California’s history and high on the list of worst American disasters.
As damaging as the earthquake and its aftershocks were, the fires that burned out of control afterward were far more destructive.[28] It has been estimated that at least 80%, and at most over 95%, of the total destruction was the result of the subsequent fires.
Anything built in California today has to meet certain standards for earthquake resistance, if it didn’t meet those it wouldn’t get built.
Also, a not-insignificant amount of earthquake resistance, in the sense of resisting the effects of an earthquake, is actually fire resistance.
