From December 1811 to February 1812, massive earthquakes shook the middle Mississippi Valley, collapsing homes, snapping large trees midtrunk, and briefly but dramatically reversing the flow of the continent’s mightiest river. For decades, people puzzled over the causes of the quakes, but by the time the nation began to recover from the Civil War, the New Madrid earthquakes had been essentially forgotten.

           

In The Lost History of the New Madrid Earthquakes, Conevery Bolton Valencius remembers this major environmental disaster, demonstrating how events that have been long forgotten, even denied and ridiculed as tall tales, were in fact enormously important at the time of their occurrence, and continue to affect us today. Valencius weaves together scientific and historical evidence to demonstrate the vast role the New Madrid earthquakes played in the United States in the early nineteenth century, shaping the settlement patterns of early western Cherokees and other Indians, heightening the credibility of Tecumseh and Tenskwatawa for their Indian League in the War of 1812, giving force to frontier religious revival, and spreading scientific inquiry. Moving into the present, Valencius explores the intertwined reasons—environmental, scientific, social, and economic—why something as consequential as major earthquakes can be lost from public knowledge, offering a cautionary tale in a world struggling to respond to global climate change amid widespread willful denial.     

           

Engagingly written and ambitiously researched—both in the scientific literature and the writings of the time—The Lost History of the New Madrid Earthquakes will be an important resource in environmental history, geology, and seismology, as well as history of science and medicine and early American and Native American history.

Since its publication in a cloth edition in 1976, Penick’s book has met with enormous regional appeal as well as critical acclaim. For the new paper edition, the author has written a new introduction. New material in the final chapter reports on the scientific inquiries into the New Madrid quakes since 1976.

Critical comments on the cloth edition: “James Penick has put together a well-written account of the quakes and their effects upon people, animals, waterways, and land. Based on the scattered accounts of the times it offers a good insight into the reactions of persons suddenly confronted with the perils of the unknown. The vivid description of the devastation wrought upon the face of the land gives a picture of dramatic change brought about by the upheaval of natural forces. In short, reading Penick’s work one is readily caught up in the total violence of the event.”—American Historical Review

“Penick provides information relevant to present studies of earthquakes in this area.”—Earthquake Information Bulletin

Although most Americans associate earthquakes with California, the tremors that shook the Mississippi valley in southeast Missouri from December 16, 1811, through February 7, 1812, are among the most violent quakes to hit the North American continent in recorded history. Collectively known as the New Madrid earthquakes, these quakes affected more than 1 million square miles. By comparison, the 1906 San Francisco earthquake affected only 60,000 square miles, less than one-sixteenth the area of the New Madrid earthquakes.

Scientists believe that each of the three greatest tremors would have measured more than 8.0 on the Richter scale, had that measuring device been in place in 1811. Vibrations were felt from the Rocky Mountains to the Atlantic coast and from Mexico to Canada. The quake zone was in constant movement during this period. Five towns in three states disappeared, islands vanished in the Mississippi River, lakes formed where there had been none before, and the river flowed backward for a brief period.

Providing eyewitness accounts from people both on the land and on the river, Bagnall captures the fears of the residents through their tales about the smells and dark vapors that filled the air, the cries of the people, the bawling of animals, and the constant roar of the river and its collapsing banks. On Shaky Ground also traces the history of the founding of New Madrid and considers the impact of the earthquakes on population and land in southeast Missouri. Predictions for future earthquakes along the New Madrid fault, as well as instructions on preparing for and surviving a quake, are also included.

Informative, clearly written, and well illustrated, On Shaky Ground will be of interest to all general readers, especially those interested in earthquakes or Missouri history.
