For centuries, Californians and the Japanese have known that they were at risk of catastrophic earthquakes, and prepared accordingly. But when a violent 7.0 earthquake rocked Haiti in 2010, hardly anyone knew the island nation was even at risk for disaster, and, tragically, no one was prepared. Over 300,000 people died as buildings that had never been designed to withstand such intense shaking toppled over and crushed their inhabitants. Now, scientists warn that it won't be long before a single, catastrophic quake kills one million people - and that it is going to strike right where we least expect it. In this groundbreaking book, renowned seismologist with the British Geological Survey Roger Musson takes us on an exhilarating journey to explore what scientists and engineers are doing to prepare us for the worst. With riveting tales of the scientists who first cracked the mystery of what causes the ground to violently shake, Musson makes plain the powerful geological forces driving earthquakes and tsunamis, and shows how amazing feats of engineering are making our cities earthquake-proof. Highlighting hotspots around the world from Mexico City to New York this is a compelling scientific adventure into nature at its fiercest.
