The above video is a collection of live footage captured during the 1989 Loma Prieta Earthquake in San Francisco, which was created by the U.S. Geological Survey. Be forewarned that it's a bit unsettling (but not gory).
See a whole slew of amateur and news footage of the 1989 earthquake on YouTube. The Loma Prieta was the first major U.S. earthquake to be broadcast on live television. (We remember watching it back in the Midwest on "A Current Affair," with Maury Povich, who used the sensationalistic term "mangled humanity," or something like that. Oh, Maury.)
