        Earthquakes: San Francisco

        The prediction of earthquakes may be inexact, but it is vital, especially when large cities such as San Francisco or Los Angeles are threatened. The San Andreas Fault and two other lesser-known faults all have the potential to deliver a massive earthquake to the San Francisco Bay area. In this video segment adapted from NOVA, a seismologist interprets earthquake data and explains how these data are used to predict the location and timing of San Francisco's next big earthquake.
