Metamorphism generates electrical and magnetic phenomena, and is influenced by these forces. Information fundamental to their combined study is presented, including examples from microtectonics, crystal physics, geophysics, seismology, mineralogy and materials science. Applications for earthquake prediction, planetary science research, alternative energy and science education are included. Work on reported seismic electric signals is analyzed and summarized. Ten hypotheses related to earthquake mechanisms and prediction are presented, as well as eighteen recommendations for further study. Eight microtectonic deformation mechanisms are explored. Two hundred seventeen descriptions of minerals exhibiting ferroelectricity, pyroelectricity or piezoelectricity are presented, with quantitative data where known. Fifty-three of these are centrosymmetric, and explanations are given for their apparent violations of crystal theory. A comprehensive list of thirty-two mechanisms that generate telluric currents is also presented, as are some novel or inexpensive experimental techniques in crystal physics.

In November 1991 the American flag was lowered for the last time at Clark Air Base in the Philippines. This act brought to an end American military presence in the Philippines that extended back over 90 years. It also represented the final act in a drama that began with the initial rumblings in April of that year of the Mount Pinatubo volcano, located about nine miles to the east of Clark. The following pages tell the remarkable story of the men and women of the Clark community and their ordeal in planning for and carrying out their evacuation from Clark in face of the impending volcanic activity. It documents the actions of those who remained on the base during the series of Mount Pinatubo's eruptions, and the packing out of the base during the subsequent months. This is the story of the "Ash Warriors," those Air Force men and women who carried out their mission in the face of an incredible series of natural disasters, including volcanic eruption, flood, typhoons, and earthquakes, all of which plagued Clark and the surrounding areas during June and July 1991. The author of The Ash Warriors knew the situation first hand. Col. Dick Anderegg was the vice commander of the 3rd Tactical Fighter Wing when the volcano erupted, and he was at Clark throughout the evacuation and standing down of the base. He brought his own personal experience to bear in writing this story. He also conducted extensive research in the archives of the Pacific Air Forces and Thirteenth Air Force, utilized scores of interviews of those who witnessed and participated in the events, and visited Clark in 1998 to see in person how the installation had changed in the eight years since the Americans left.

Because most sedimentary rocks encountered in oil and gas exploration are effectively anisotropic, it is imperative to properly estimate seismic anisotropy and incorporate it into data-processing and imaging algorithms. Seismology of Azimuthally Anisotropic Media and Seismic Fracture Characterization (SEG Geophysical References Series No. 17) presents a systematic analysis of seismic signatures for azimuthally anisotropic media and describes anisotropic inversion/processing methods for wide-azimuth reflection data and VSP (vertical seismic profiling) surveys. The main focus is on kinematic parameter-estimation techniques operating with P-waves as well as with the combination of PP and PS (mode-converted) data. The part devoted to prestack amplitudes includes azimuthal AVO (amplitude variation with offset) analysis and a concise treatment of attenuation coefficients, which are highly sensitive to the presence of anisotropy. Discussion of fracture characterization is based on modern effective media theories and illustrates both the potential and limitations of seismic methods. Field-data examples highlight the improvements achieved by accounting for anisotropy in seismic processing, imaging, and fracture detection.

Despite growing evidence of geothermic activity under America's first and foremost national park, it took geologists a long time to realize that there was actually a volcano beneath Yellowstone. And then, why couldn't they find the caldera or crater? Because, as an aerial photograph finally revealed, the caldera is 45 miles wide, encompassing all of Yellowstone. What will happen, in human terms, when it erupts?
Greg Breining explores the shocking answer to this question and others in a scientific yet accessible look at the enormous natural disaster brewing beneath the surface of the United States. Yellowstone is one of the world's five "super volcanoes." When it erupts, much of the nation will be hit hard.
Though historically Yellowstone has erupted about every 600,000 years, it has not done so for 630,000, meaning it is 30,000 years overdue. Starting with a scenario of what will happen when Yellowstone blows, this fascinating study describes how volcanoes function and includes a timeline of famous volcanic eruptions throughout history.

Written by the author of "The Forecasting of Volcano Eruptions," this book tells about the color, splendor, nature and life. About the people who are warm, friendly and, of course, very French. Reunion Island, located in the Indian Ocean, is currently believed to have been discovered early in the 16th century by the Portuguese navigator Pedro de Mascarenhas. In the year 1638, Reunion Island was claimed by France as a stopover point for mercantile ships on their way to India. The French East India Company established a small colony on Reunion in the year 1665. Originally called Ile de Bourbon, it was named Reunion in 1793 during the French Revolution.

Forecasting the time, place, and character of a volcanic eruption is one of the major goals of volcanology. It is also one of the most difficult goals to achieve. Until recently, people living in a volcano's shadow had little help anticipating an eruption. A major volcanic event might strike with no warning at all. In the past 300 years, volcanic eruptions, most of them unexpected, have killed more than 250,000 people. In 2000, experts estimated that 500 million people were living in areas at risk from catastrophic volcanic eruptions. This book describes the strides that have made in eruption forecasting in recent years and explores why accurately predicting volcanic events remains difficult.

Based on the methodologies in this book, Eruption Pro 10.6, to our knowledge, it is the only software programme of its type anywhere in the world. Eruption Pro 10.6 performs analysis on current available volcano eruption data from both historical and current available eruption data, near real-time measurement data including, seismic, deformation, thermal, frequency of eruption analysis, solar & lunar influences, crater lake temperature (if applicable), COSPEC, & statistical procedures. The newest version also accounts for, albeit very small, contributions due to lunar and solar influences.

On November 1, 1755--All Saints' Day--a massive earthquake struck Europe's Iberian Peninsula and destroyed the city of Lisbon. Churches collapsed upon thousands of worshippers celebrating the holy day. "Earthquakes in Human History" tells the story of that calamity and other epic earthquakes. The authors, Jelle Zeilinga de Boer and Donald Theodore Sanders, recapture the power of their previous book, "Volcanoes in Human History." They vividly explain the geological processes responsible for earthquakes, and they describe how these events have had long-lasting aftereffects on human societies and cultures. Their accounts are enlivened with quotations from contemporary literature and from later reports.

In the chaos following the Lisbon quake, government and church leaders vied for control. The Marques de Pombal rose to power and became a virtual dictator. As a result, the Roman Catholic Jesuit Order lost much of its influence in Portugal. Voltaire wrote his satirical work "Candide" to refute the philosophy of "optimism," the belief that God had created a perfect world. And the 1755 earthquake sparked the search for a scientific understanding of natural disasters.

Ranging from an examination of temblors mentioned in the Bible, to a richly detailed account of the 1906 catastrophe in San Francisco, to Japan's Great Kanto Earthquake of 1923, to the Peruvian earthquake in 1970 (the Western Hemisphere's greatest natural disaster), this book is an unequaled testament to a natural phenomenon that can be not only terrifying but also threatening to humankind's fragile existence, always at risk because of destructive powers beyond our control."

The ultimate introduction to seismology, written by distinguished scholar and Professor Bruce Bolt, of the University of California, Berkeley, this newly updated edition will provide the best foundation in the field for your introductory students.

"This is the most complete reference available on Texas earthquakes.... Its general information on earthquakes, presented in a humorous and understandable manner, will even make the text attractive to non-Texans who want to know more about earthquakes." -- Diane I. Doser, Professor of Geology, University of Texas at El Paso

When nature goes haywire in Texas, it isn't usually an earthshaking event. Though droughts, floods, tornadoes, and hail all keep Texans talking about the unpredictable weather, when it comes to earthquakes, most of us think we're on terra firma in this state. But we're wrong! Nearly every year, earthquakes large enough to be felt by the public occur somewhere in Texas.

This entertaining, yet authoritative book covers "all you really need to know" about earthquakes in general and in Texas specifically. The authors explain how earthquakes are caused by natural forces or human activities, how they're measured, how they can be predicted, and how citizens and governments should prepare for them. They also thoroughly discuss earthquakes in Texas, looking at the occurrences and assessing the risks region by region and comparing the amount of seismic activity in Texas to other parts of the country and the world. The book concludes with a compendium of over one hundred recorded earthquakes in Texas from 1811 to 2000 that briefly describes the location, timing, and effects of each event.

The Story of Earthquakes and Volcanoes

"An excellent survey of earthquakes and their effects--their mystery, terror, and science, and how we are learning to control their forces."--Christopher Arnold, president, Building Systems Development

We expect everything to move except the earth! Anyone who has ever experienced an earthquake or seen news footage of cracking buildings and swaying bridges can appreciate the awe and fear that moving earth can inspire. This book unravels the mystery and the marvel of one of natures most unpredictable and terrifying phenomena: the earthquake.

With a lively text and over 100 illustrations, two of the worlds premier structural engineers take us on a fascinating trip from the Earths beginnings to recent developments in seismic technology. It is one told through the stories of the worst natural disasters of all time: Lisbon, San Francisco, Alaska, Vesuvius, Krakatau, Mount St. Helens. These earthshaking events form the background for an exploration of the nature of earthquakes and volcanoes, the prediction of their behavior, and an up-to-date description of the measures we can take to protect ourselves from their destructive nature.

The first effective seismographs were built between 1879 and 1890. In 1885, E. S. Holden, an astronomer and then president of the University of California, instigated the purchase of the best available instruments of the time "to keep a register of all earthquake shocks in order to be able to control the positions of astronomical instruments." These seismographs were installed two years later at Lick Observatory on Mt. Hamilton and at the Berkeley campus of the University. Over the years those stations have been upgraded and joined by other seismographic stations administered at Berkeley, to become the oldest continuously operating stations in the Western Hemisphere. The first hundred years of the Seismographic Stations of the University of California at Berkeley, years in which seismology has often assumed an unforeseen role in issues of societal and political importance, ended in 1987. To celebrate the centennial a distinguished group of fellows, staff, and friends of the Stations met on the Berkeley campus in May 1987. The papers they presented are gathered in this book, a distillation of the current state of the art in observatory seismology. Ranging through subjects of past, present, and future seismological interest, they provide a benchmark reference for years to come. This title is part of UC Press's Voices Revived program, which commemorates University of California Press's mission to seek out and cultivate the brightest minds and give them voice, reach, and impact. Drawing on a backlist dating to 1893, Voices Revived makes high-quality, peer-reviewed scholarship accessible once again using print-on-demand technology. This title was originally published in 1989.

Exploiting Seismic Waveforms introduces a range of recent developments in seismology including the application of correlation techniques, understanding of multi-scale heterogeneity and the extraction of structure and source information by seismic waveform inversion. It provides a full treatment of correlation methods for seismic noise and event signals, and develops inverse methods for both sources and structure. Higher frequency components of seismograms are frequently neglected, or removed by filtering, but they contain information about seismic structure on scales that cannot be revealed by seismic tomography. Sufficient computational resources are now available for waveform inversion for 3-D structure to be a practical procedure and this book describes suitable algorithms and examples reflecting current best practice. Intended for students and researchers in seismology, this book provides a physical understanding of seismic waveforms and the way that different aspects of the seismic wavefield are revealed by the way that seismic data are handled.

Seismic data must be interpreted using digital signal processing techniques in order to create accurate representations of petroleum reservoirs and the interior structure of the Earth. This book provides an advanced overview of digital signal processing (DSP) and its applications to exploration seismology using real-world examples. The book begins by introducing seismic theory, describing how to identify seismic events in terms of signals and noise, and how to convert seismic data into the language of DSP. Deterministic DSP is then covered, together with non-conventional sampling techniques. The final part covers statistical seismic signal processing via Wiener optimum filtering, deconvolution, linear-prediction filtering and seismic wavelet processing. With over sixty end-of-chapter exercises, seismic data sets and data processing MATLAB codes included, this is an ideal resource for electrical engineering students unfamiliar with seismic data, and for Earth Scientists and petroleum professionals interested in DSP techniques.

This study provides innovative mathematical models for assessing the eruption probability and associated volcanic hazards, and applies them to the Campi Flegrei caldera in Italy. Throughout the book, significant attention is devoted to quantifying the sources of uncertainty affecting the forecast estimates. The Campi Flegrei caldera is certainly one of the world's highest-risk volcanoes, with more than 70 eruptions over the last 15,000 years, prevalently explosive ones of varying magnitude, intensity and vent location. In the second half of the twentieth century the volcano apparently once again entered a phase of unrest that continues to the present. Hundreds of thousands of people live inside the caldera and over a million more in the nearby city of Naples, making a future eruption of Campi Flegrei an event with potentially catastrophic consequences at the national and European levels.

Japan, which is among the most earthquake-prone regions in the world, has a long history of responding to seismic disasters. However, despite advances in earthquake-related safety technologies, the destructiveness of the magnitude 9 class earthquake and tsunami that struck the country on 3/11 raised profound questions about how societies can deal effectively with seismic hazards. This important book places the devastating earthquake, tsunami, and nuclear meltdown disaster in historical perspective, examining conceptions of earthquakes since the seventeenth century, the diverse ways actual earthquakes and their aftermath played out, and their enduring social and scientific significance. By looking backward, Gregory Smits identifies future pitfalls to avoid and assesses the allocation of resources for dealing with future earthquake and tsunami disasters. He criticizes Japan's postwar quest for earthquake prediction and the concept of "characteristic" earthquakes. Smits argues that earthquakes are so chaotic as to be unpredictable, not only geologically but also in their social and cultural effects. Therefore, he contends, the best hope for future disaster mitigation is antiseismic engineering and flexible disaster-relief capabilities. As the first sustained historical analysis of destructive earthquakes and tsunamis, this book is an essential resource for anyone interested in Japan, natural disasters, seismology, and environmental history.

The author gives a systematic account of various Earth Movements. These comprise Earthquakes, or the sudden violent movements of the ground; Earth Tremors, or minute movements which escape our attention by the smallness of their amplitude; Earth Pulsations, or movements which are overlooked on account of the length of their period; and lastly, Earth Oscillations, or movements of long period and large amplitude which attract so much attention from their geological importance.
