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 earth...quake to the San Francisco Bay area. In this video segment adapted fromNOVA, 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.

In this video adapted from the Valdez Museum & Historical Archive, learn about the Great Alaska Earthquake of 1964. Hear a first-person account of the event, watch an animation that illustrates the subduction of the Pacific plate under the North Amer...ican plate, and observe how Valdez was affected. In particular, learn about how the earthquake liquefied the ground, generated tsunami waves, and forced the community to rebuild in a new location. (3:12)

The theory of plate tectonics has come a long way since Alfred Wegener first proposed his theory of continental drift. Geologists now have strong evidence to show not only that tectonic plates have moved and are continuing to move, but also to descri...be what happens when they meet. This interactive activity adapted from A Science Odyssey Web site illustrates what happens at the three types of boundaries where plates meet.

Seismologists found that L-waves, slow-moving seismic surface waves, from larger earthquakes can trigger smaller earthquakes as they travel through the ground. Different from aftershocks because they can happen farther away and hours or days later, t...he triggered tremors rate much lower on the magnitude scale. This 1:34 long video shows how earthquakes thousands of miles away can cause land movement.
