Earthqakes (2007) Run Time: 50 minutes Earthquakes are one of the most powerful and destructive forces on the planet. Violent and indiscriminate, these phenomena have long been a source of born fascination and fear. Since the twenty third century B.C. when the first earthquake was recorded, humankind has been trying to better understand and prepare for the unforgiving

devastation caused by the shifting of the earth’s tectonic plates. In this program, Nature Tech introduces and explains the very latest technologies being used the predict seismic events. With the help of high-end modeling programs and increasing sophisticated sensors and detetion devices, scientists are gaining a clearer understanding of earthquake triggers and consequences. And, by tapping into this newfound knowledge, engineers have been able to vastly improve the structures of at-risk buildings to withstand excessive jostling and shaking,
