In Earthquakes, students discover how the underground movement of rocks, along with stresses on Earth's crust, produce surface-level tremors. Learn how scientists determine where the hypocenter and epicenter of a quake occur while exploring the destructive power of seismic waves. Investigate some of the most destructive earthquakes of the 20th century, and learn how seismologists predict where they will occur. A visit to the University of California at Berkeley showcases the use of a "shaker table" by engineers designing buildings, while a fun, hands-on investigation demonstrates how students can build a simple model of a seismograph and put it through a simulated earthquake. Part of the Earth Science in Action DVD Series. A Teacher's Guide is included and available online. 23 minutes. Grades 5 to 8.
