San Francisco Earthquake and Fire of 1906

At approximately 5:12 a.m. on April 18, 1906, a powerful earthquake ripped through the city of San Francisco. Roadways rose and fell like ocean waves. Crumbling walls and chimneys rained glass and bricks onto sidewalks and streets, and crowded rooming houses suddenly vanished into heaps of splintered wood. Yet San Francisco's ordeal had only begun. The violent trembling of the ground had hardly stilled when dozens of fires sparked by damaged chimneys and severed gas lines ignited throughout the stricken city. By April 21st, the fires were finally brought under control, but the city had lost nearly 30,000 buildings to the earthquake and ensuing blazes, half of its population was homeless, and some 3,000 were dead. Until Hurricane Katrina slammed into the Gulf Coast in 2005, the San Francisco calamity of 1906 was the worst natural disaster in U.S. history.
