On April 18, 1906, a massive earthquake with an estimated magnitude of 7.7 hit the city of San Francisco and much of California's northern coast. The earthquake and subsequent fires are thought to have killed 3,000 people, the biggest natural disaster in California's history. Ruins in vicinity of Post and Grant Avenue are seen in this 1906 photograph. US National Archives
In this photograph, taken during the quake's aftermath, San Francisco's Mission district burns. Over 80% of the city was destroyed, and the losses may have been the reason Los Angeles became the largest and most important city in the West, rather than San Francisco, a city once considered the 'gateway to the Pacific.'

San Francisco lies in ruins on May 28, 1906, about six weeks after the 1906 San Francisco earthquake and fire. This photo was taken from a camera suspended on a kite, perhaps 1,000 feet above the city. The tower of the Ferry Building can be seen at the bay end of Market Street. The water in the foreground is San Francisco Bay, with the Golden Gate to the right, rear. Note the absence of the Golden Gate Bridge and the San Francisco-Oakland Bay Bridge, both of which had yet to be constructed. George R. Lawrence

The earthquake also affected the campus of Stanford University in Palo Alto. The image of the fallen statue of zoologist Louis Agassiz outside the Zoology building has since become one of the iconic images of the earthquake.
Photographer Arnold Genthe recalled the scene in his book, 'As I Remember.' This photo of his shows 'the results of the earth quake, the beginning of the fire and the attitude of the people.' It was taken the morning of the first day of the fire. Arnold Genthe
