There are other segments of this series on WatchKnow. This is the 'Earthquake Country' series which is suitable for middle school and high school students. Through live-action demonstrations and vivid animations, Dr. Pat Abbott explains how earthquak...es have shaped the scenery and the character of the greater Los Angeles area. Dr. Abbott shows how faults capable of large earthquakes lie beneath most of the area, posing great risk to the millions of people living in earthquake country. Animations illustrate how and why earthquakes happen, how mountains and valleys have formed as a result, how the ground will shake in large earthquakes, and why this shaking is so destructive to buildings. Dr. Abbott also shows how to evaluate your home for earthquake safety and explains how to reduce the devastating effects of earthquakes. This video is part of Dr. Abbott's "Written in Stone" series.

Witness the destructive power of earthquakes, from home videos taken during a tremor. Video goes inside the Earth to show how an earthquake starts. Earth is covered by plates, when the plates are moved by the heat of the inner Earth, they grind aga...inst each other along lines called faults. When the plates motion is blocked stress builds up, finally the fault gives way. The released energy moves through the Earth called seismic waves. Seismic waves are measured by scientists on seismographs. Only about a thousand of these waves is strong enough to cause damage. About 10,000 people die each year in earthquakes. The strongest earthquake to date in North America measured 9.2, and was in Alaska on March 28, 1964. Video is good quality and has good information. Good for elementary grade and middle school students.
