National Earthquake Resilience


Book Description

The United States will certainly be subject to damaging earthquakes in the future. Some of these earthquakes will occur in highly populated and vulnerable areas. Coping with moderate earthquakes is not a reliable indicator of preparedness for a major earthquake in a populated area. The recent, disastrous, magnitude-9 earthquake that struck northern Japan demonstrates the threat that earthquakes pose. Moreover, the cascading nature of impacts-the earthquake causing a tsunami, cutting electrical power supplies, and stopping the pumps needed to cool nuclear reactors-demonstrates the potential complexity of an earthquake disaster. Such compound disasters can strike any earthquake-prone populated area. National Earthquake Resilience presents a roadmap for increasing our national resilience to earthquakes. The National Earthquake Hazards Reduction Program (NEHRP) is the multi-agency program mandated by Congress to undertake activities to reduce the effects of future earthquakes in the United States. The National Institute of Standards and Technology (NIST)-the lead NEHRP agency-commissioned the National Research Council (NRC) to develop a roadmap for earthquake hazard and risk reduction in the United States that would be based on the goals and objectives for achieving national earthquake resilience described in the 2008 NEHRP Strategic Plan. National Earthquake Resilience does this by assessing the activities and costs that would be required for the nation to achieve earthquake resilience in 20 years. National Earthquake Resilience interprets resilience broadly to incorporate engineering/science (physical), social/economic (behavioral), and institutional (governing) dimensions. Resilience encompasses both pre-disaster preparedness activities and post-disaster response. In combination, these will enhance the robustness of communities in all earthquake-vulnerable regions of our nation so that they can function adequately following damaging earthquakes. While National Earthquake Resilience is written primarily for the NEHRP, it also speaks to a broader audience of policy makers, earth scientists, and emergency managers.

The Lost History of the New Madrid Earthquakes


Book Description

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.




Earthquakes


Book Description

An earthquake is a natural disaster that causes damage world-wide. Not only earthquakes of high magnitude, but also those of small magnitude that strike unprepared regions can cause economic and social consequences, and many casualties. Unlike other natural disasters, the exact time of an earthquake cannot be estimated; scientists can only predict the timeline and magnitude based on the history of earthquakes in a region. Even though current technology cannot predict the precise time, location or magnitude, public awareness about the estimations allows both individuals and government to be ready for their devastating effects. This book begins by discussing how public awareness about the effects of earthquakes and how to prepare for a possible earthquake which can potentially save lives. The book then continues with topics that include seismic PRA; seismic safety assessments of existing buildings; psychiatric reactions of individuals to earthquakes; possible relation between an intense earthquake and the voltage signal generated by atmospheric ionic currents and/or sudden change of the electric field in the air; and others.




Between Two Earthquakes


Book Description

This handbook addresses three areas of concern for the museum administrator concerning the protection of historic buildings, monuments, and archaeological sites located in seismic areas. It proposes pre-disaster measures such as taking accurate and complete documentation (photogrammetry is discussed in one of the 13 appendixes), risk awareness, planning, maintenance and inspections, etc. Second, when an earthquake strikes, the immediate emergency steps necessary to protect life and property are indicated; and after the earthquake, the strengthening of valuable cultural property (based on the Modified Mercalli Intensity Scale, also in an appendix) should be included in the general program of prevention maintenance along with the repairs discussed in detail applicable to each architectural element, and to the site as a whole.




Living on an Active Earth


Book Description

The destructive force of earthquakes has stimulated human inquiry since ancient times, yet the scientific study of earthquakes is a surprisingly recent endeavor. Instrumental recordings of earthquakes were not made until the second half of the 19th century, and the primary mechanism for generating seismic waves was not identified until the beginning of the 20th century. From this recent start, a range of laboratory, field, and theoretical investigations have developed into a vigorous new discipline: the science of earthquakes. As a basic science, it provides a comprehensive understanding of earthquake behavior and related phenomena in the Earth and other terrestrial planets. As an applied science, it provides a knowledge base of great practical value for a global society whose infrastructure is built on the Earth's active crust. This book describes the growth and origins of earthquake science and identifies research and data collection efforts that will strengthen the scientific and social contributions of this exciting new discipline.
