1906 San Francisco Earthquake: Four Days Before

A massive earthquake famously struck San Francisco on this day back in 1906, an anniversary that brought to mind this excellent 60 Minutes piece about stunning, digitally-restored movie footage of San Francisco taken just four days before that earthquake (and subsequent fire) nearly destroyed the city. The camera is mounted on the front of a streetcar rolling down Market Street, vying with horse-drawn carriages and automobiles and pedestrians. "The film is a time traveler's glimpse of a joyous city on the brink of disaster," explains Morley Safer."The odds are, some of the people you see have just days to live."
