On April 18th, 1906 at 5:12 in the morning, the coast of Northern California was hit by an earthquake that is considered to be the worst natural disaster in the state's history. The quake pre-dated the Richter scale measurement by thirty years; experts estimate the magnitude of the quake on the modern moment magnitude scale as anywhere from 7.8 to 8.25.
The earthquake caused deadly fires to break out, which weren't extinguished for several days. In the wake of the disaster, more than 3,000 people died and over 80% of San Francisco was destroyed.
