The Big One and what we can do to get ready for it. Mention the word earthquake and most people think of California. But while the Golden State shakes on a regular basis, Washington State, Oregon, and British Columbia are located in a zone that can produce the world's biggest earthquakes and tsunamis. In the eastern part of the continent, small cities and large, from Ottawa to Montréal to New York City, sit in active earthquake zones. In fact, more than 100-million North Americans live in active seismic zones, many of whom do not realize the risk to their community. For more than a decade, Gregor Craigie interviewed scientists, engineers, and emergency planners about earthquakes, disaster response, and resilience. He has also collected vivid first-hand accounts from people who have survived deadly earthquakes. His fascinating and deeply researched book dives headfirst into explaining the science behind The Big One -- and asks what we can do now to prepare ourselves for events geologists say aren't a matter of if, but when.
