The great San Francisco earthquake occurred this date in 1906. It struck the coast of northern California at 5:12 AM with an estimated magnitude of 7.8. Three thousand people died and over 80% of the city was destroyed. The events are remembered as one of the worst and deadliest natural disasters in the history of the United States.
According to findings published in the Journal of Geophysical Research, severe deformations in the earth’s crust took place both before and after the earthquake’s impact. Accumulated strain on the faults in the system was relieved during the earthquake, which is the supposed cause of the damage along the 450-kilometer-long segment of the San Andreas plate boundary. The main shock epicenter occurred offshore about two miles from the city. Shaking was felt from Oregon to Los Angeles, and inland as far as central Nevada. (from Wikipedia)
