In the winter of 1811-12, a series of large earthquakes in the New Madrid seismic zone-often incorrectly described as the biggest ever to hit the United States-shook the Midwest. Today the federal government ranks the hazard in the Midwest as high as California's and is pressuring communities to undertake expensive preparations for disaster. Disaster Deferred revisits these earthquakes, the legends surrounding them, and the predictions of doom following in their wake. Seth Stein clearly explains the techniques seismologists use to study Midwestern quakes and estimate their danger. Detailing how limited scientific knowledge, bureaucratic instincts, and the media's love of a good story have exaggerated these hazards, Stein calmly debunks the hype surrounding such predictions and encourages the formulation of more sensible, less costly policy.
