Starting December 16, 1811, with an 8.6 magnitude earthquake, the greatest release of seismic energy in American History occurred with over 2000 earthquakes in five months. Collectively called "The New Madrid Earthquake," the largest was an 8.8 on February 7, 1812, that made the Mississippi River run backwards and swallowed five whole towns. These quakes were felt from Canada to Mexico, from Cuba to Wyoming, from the Rocky Mountains to the East Coast. They rang church bells in Boston, toppled hundreds of chimneys in Cincinnati, and damaged wineries in Virginia hundreds of miles from the epicenter. Yet, most people are unaware of this historic event and do not realize that it will happen again. This book tells in compelling and graphic language the experiences of people living at the time, including Indians, slaves, white settlers, and the politicians of the day. It also provides detailed information and probabilities on future New Madrid earthquakes and how you can prepare for them.

The great New Madrid earthquakes of 1811-12 were the greatest release of seismic energy in the history of the lower 48 states. More than 2000 shocks in five months, five of which were at least 8.0 on the Richter scale. Located along the central Mississippi River valley, these quakes were felt from the Rockies the Eastern Seaboard, from Canada to Mexico. The Mississippi River ran backwards. Five whole towns disappeared. Gapping crevasses open and people were swallowed alive. Hundreds of chimnies were thrown down in Cincinnati 400 miles from the epicenter while church bells rang in Boston, 1000 miles from the source. Every man, woman and child living the United States at the time felt these temblors. This book tells the personal stories, both heroic and tragic, and discusses in detail when it will happen again and how to be ready.

A series of great earthquakes struck the central Mississippi River valley during the winter of 1811-12 and changed the landscape forever. At five of these more than 2,000 events were at least 8.0 on the Richter scale. In their wake, an area about the size of New Jersey, about 150 miles long and 80 miles wide, was left with thousands of gashes and scars still visible today, almost 200 years later. Sand boils, explosion sand craters, fissures, crevasses, seismic sand ridges, earthquake ponds, sunk lands, earthquake lakes, surface faults, landslides, and a host of other morphoseismic features abound throughout the region. This book contains 150 photos, maps, and drawings of these with a description of their impact on life there today--how it effects transportion, construction, agriculture, and the lives of those who live in or near the fault zone. For example, vast areas were turned into temporary quicksand during the temblors (seismic liquefaction), leaving numerous places sensitive to vibration, even today. One of these locations is just outside of New Madrid, Missouri, where a railroad crosses. When trains happen to cross at just the right speed, weight, and length, the rumbling of the cars triggers temporary quicksand conditions, causing the rails to sag and derailing the train. The last time this happened was in 1993. So here we have trains being derailed today by an earthquake that happened 200 years ago. That's why we call it "The Earthquake that Never Went Away."
