It’s a bleak scenario. A massive earthquake along the New Madrid fault kills or injures 60,000 people in Tennessee. A quarter of a million people are homeless. The Memphis airport – the country’s biggest air terminal for packages – goes off-line. Major oil and gas pipelines across Tennessee rupture, causing shortages in the Northeast. In Missouri, another 15,000 people are hurt or dead. Cities and towns throughout the central U.S. lose power and water for months. Losses stack up to hundreds of billions of dollars.
