History

Historical Context

The 1906 San Francisco earthquake, registering a magnitude of 7.9, devastated the city, causing over 3,000 deaths and destroying approximately 80% of its structures. This event highlighted California's seismic risks, particularly along the San Andreas Fault. Today, the Hayward Fault poses ongoing threats, with experts estimating a 6.7 magnitude earthquake is likely in the Bay Area within the next 30 years.
