Rebuilding Destroyed Cities

San Francisco, 1906
The 1906 San Francisco earthquake remains one of the most legendary moments in the history of California — a state that has seen more than its share of strong quakes. Most of the city's damage was caused by fires sparked by ruptured gas lines that burned out of control for days. News of the disaster spread quickly; within weeks, hundreds of thousands of dollars had been donated from around the world to the city's relief effort.
