The Big One: Preparing for mid-America earthquake

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.

Fortunately, this magnitude 7.7 temblor is not real but rather a scenario imagined by the Mid-America Earthquake Center and the Institute for Crisis, Disaster and Risk Management at George Washington University. The goal of their 2008 analysis was to plan for a modern recurrence of quakes that happened along the New Madrid fault more than 200 years ago, in 1811 and 1812.

No one alive has experienced a major earthquake in the Midwest, yet geologists say it’s only a matter of time. That puts a lot of uncertainty on disaster officials. Their earthquake precautions – quake-resistant building codes, for example – have never been reality tested. Some question if enough has been done to strengthen existing buildings, schools and other infrastructure. It is difficult to prepare for a geological catastrophe the public cannot see and has never experienced.

“We mostly react to disasters, and it’s been extremely rare that we get ahead of things,” said Claire Rubin, a disaster response specialist in Arlington, Va. “A lot of hard problems don’t get solved. They get moved around and passed along.”

Steven L. Lueker is among disaster response officials who worry about the New Madrid fault and another fault to the north, in the Wabash Valley. He’s the emergency management coordinator for Jefferson County in Southern Illinois, and he rattles off likely impact statistics. One of the most important: The New Madrid fault is expected to generate a large-scale earthquake within the next 50 years.

    Flying snakes sound like creatures from a bad B-movie, but these serpents are elegant gliders that have evolved a special skill that sets them apart. In two new studies, engineers have used simulations to try to decipher how the wingless reptile manages to remain airborne despite its lack of flight appendages.

  • missing-plane.jpg In this tech age, how can a plane go missing?

    Call 911 from the side of the road, and GPS satellites can tell dispatchers exactly where to send help. Airline passengers have access to detailed maps that show exactly where they are during their journey. Hop onto WiFi, and somehow Google knows whether you're logging on from Lima or London, and will give you detailed suggestions about what to eat.
