In 45 seconds on a summer night in Turkey, a shift in the Earth left 250,000 people homeless—and more than 17,000 dead. In this program, a geologist, seismologist, geophysicist, and others extract the painful lessons from Izmit’s tragic upheaval so that other high-risk cities—nearby Istanbul, for instance, and Los Angeles, which lies on a fault line nearly identical to the one in Turkey—might better prepare themselves for the earthquakes that scientists see as inevitable. Gripping news footage captures the devastation and high-tech rescue efforts while animated computer graphics and demonstrations reveal the earth science behind such cataclysms.
