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...
As the 20th century began, swamps with immense timber resources covered much of the Missouri Bootheel. After investors harvested the timber, the landscape became overgrown. The conversion of swampland to farmland began with small drainage projects but complete reclamation was made possible by a system of ditches dug by the Little River Drainage District--the largest in the U.S., excavating more earth than for the Panama Canal. Farming quickly took over. The devastation of Southern cotton fields by boll weevils in the early 1920s brought to the cooler Bootheel an influx of black and white sharecroppers and cotton became the principal crop. Conflict over New Deal subsidies to increase cotton prices by reducing production led to the 1939 Sharecropper Demonstration, foreshadowing civil rights protests three decades later.
The renowned seismologists C.P. Rajendran and Kusala Rajendran offer a riveting story of the Indian earthquakes, their science, history and impact. Like all other natural phenomena, earthquakes are part of life-sustaining forces—the creators of the mountains, valleys and springs or even deserts on Earth—a theatre where the show never ends. The book takes the readers to some exciting parts of India to show how earthquakes change the topography where a sea existed not far in the past—now a salt marsh, affecting the social life, trade and livelihood. The book discusses the likelihood of the next big earthquake in the Himalayas against the backdrop of the devastating earlier ones revealed by archaeology, history and geology. It probes the causes and aftermath of the devastating Indian Ocean tsunami of 2004 and gives a glimpse of the past. The high-impact earthquakes will happen, but they need not always end up as human catastrophes. The authors have spent much of their professional lives studying the earthquakes in India and abroad. They tell us from their vast experience how to negotiate the impacts of earthquakes and related hazards by following science-based strategies.
A "superb cautionary tale (that) should be required reading for every Californian" (Mike Davis, author of "City of Quartz"), "Magnitude 8" reaches beyond the earthshaking moment to examine the mythology, culture, social implications, politics, and science of earthquakes. Map.
Applied Geology is a multidisciplinary subject that interacts with other disciplines, such as mineralogy, petrology, structural geology, hydrogeology, seismic engineering, rock engineering, soil mechanics, geophysics, remote sensing (RS-GIS-GPS), environmental geology, etc. This book, entitled Applied Geology, is the only one of its kind in the Indian market that caters to the needs of all these subjects. This book covers all aspects of Applied Geology and is intended to serve BTech students. A plethora of examples and case studies relevant to the Indian context have been included for better understanding of the geological challenges faced by engineers.
