How can the drama and power of an actual earthquake be brought online? It’s a difficult task, but the good and talented people at the Exploratorium deserve multiple huzzahs for their fine efforts on this site. Designed to provide some basic information about the nature of earthquakes, the site contains five primary sections. Under the “Quake Basics” heading, visitors can expect to learn about the basics of earthquakes, including some nice sections on plate tectonics, faults, and how scientists measure such phenomena. As the Exploratorium is based on San Francisco, visitors should not be surprised to find that the section titled “Great Shakes” includes information on the 1906 earthquake and the devastating quake of 1989 as well. There are some nice video clips here, including a video taken during the 1989 World Series and shots of the damage wrought by the quake in Santa Cruz.
