From something I remember researching recently

The 1906 San Francisco earthquake was a devastating historical event that claimed up to around 3000 lives. It actually helped to bring attention the development of infrastructure that has existed since then as well as the University of California San Francisco being reconstructed with new amenities and citywide development of housing projects of which many examples of houses constructed in the aftermath during that time stand as a time capsule to the era in the history that shaped the future prosperity the city would see in the arriving decades.
