Professionally presented through the "American Experience" Series - The Great San Francisco Quake is unanimously considered by all to be the worst natural disaster in U.S. history.
Taking place in 1906 (on Wed., April 15 @ 5:12 am), this devastating quake (which certainly caught everyone off guard) literally toppled thousands of buildings (leaving a contortion of stone everywhere) and left half the city's 400,000 citizens homeless.
Through stills, and vintage "before & after" footage, along with interviews with quake survivors (recalling the event as children) - This historical documentary (with its 56-minute running time) takes a look at San Francisco then (as well as beyond the effects of this natural catastrophe) as it proudly boasts of man's triumph over the forces of nature.
