Anniversary of 1906 San Francisco earthquake

April 18, 2012 will mark the 106th anniversary of the 1906 San Francisco earthquake. Three of the four known living survivors of the quake were in attendance at the annual ceremony at Lotta's Fountain, the intersection of Market, Geary and Kearny. The gathering marked a moment of silence before sirens wailed at 5:12 a.m., the moment the earth shook and set off the fire that would destroy most of the city. In this photograph, a firefighter is seen rescuing people from a building destroyed after the quake.
