episode description
Can earthquakes be predicted? Researchers are now identifying the slow-moving clues that may foreshadow violent quakes and studying active faults below the earth's surface. Their work may provide even a few seconds of warning, which in earthquake country can give a vital warning to open elevator doors, slow down trains and alert firefighters. As more and more people around the world build and buy homes on hillsides, landslides are becoming a bigger risk. Meet the geologists working to understand and predict these natural disasters. And what about tsunamis? Investigate the history of the world’s seismic swells and discover the methods researchers use to gather the information that will help them understand the geologic history of tsunamis and when and where they may strike again.
