The great San Francisco earthquake occurred on this day in 1906. With an estimated magnitude of 7.9, this earthquake destroyed most of the City of San Francisco. The earthquake damage was exacerbated by the multiple fires that broke out as a result of broken gas lines from the earthquake shaking, and which burned over many days. Most of the City's residents were left homeless after the earthquake.This earthquake is noted as the deadliest earthquake in the history of the United States with over 3000 casualties.
