Popular culture is flourishing again, with a renewed interest in the ET and UFO phenomena. We are inundated with films, TV programmes and books, plus many conspiracy theories, dealing with the phenomena. Governments and security agencies are denying any interest in the issue, yet releasing masses of documents (mostly unreadable) after being compelled to, by the Freedom of Information Act. Such speculation and documentation in ancient writings suggests that an unearthly presence has been in Earth-space for many generations. The question of this situation must reach a culminating point sometime in the near future. This book is concerned with the cultural shock and social disorientation that would obviously occur with a sudden appearance en-mass of an alien race finally revealing themselves to humanity and how the people of Earth would react.

Modern Global Seismology, Second Edition, is a complete, self-contained primer on seismology, featuring extensive coverage of all related aspects-from observational data through prediction-and emphasizing the fundamental theories and physics governing seismic waves, both natural and anthropogenic. Based on thoroughly class-tested material, the text provides a unique perspective on Earth's large-scale internal structure and dynamic processes, particularly earthquake sources, and the application of theory to the dynamic processes of the earth's upper layer. This insightful new edition is designed for accessibility and comprehension for graduate students entering the field. Exploration seismologists will also find it an invaluable resource on topics such as elastic-wave propagation, seismic instrumentation, and seismogram analysis.

Time Series Analysis in Seismology: Practical Applications provides technical assistance and coverage of available methods to professionals working in the field of seismology. Beginning with a thorough review of open problems in geophysics, including tectonic plate dynamics, localization of solitons, and forecasting, the book goes on to describe the various types of time series or punctual processes obtained from those systems. Additionally, the book describes a variety of methods and techniques relating to seismology and includes a discussion of future developments and improvements. Time Series Analysis in Seismology offers a concise presentation of the most recent advances in the analysis of geophysical data, particularly with regard to seismology, making it a valuable tool for researchers and students working in seismology and geophysics.

In this work, some of the latest advantages in the field of induced seismicity are concentrated for mining-induced (MIS), reservoir-induced (RIS), injection-induced (IIS) and extraction-induced (EIS) seismicity. Included are case studies and generalizations of investigations.

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.

The Geology of the Canary Islands provides a concise overview of the geology and volcanology of the Canary Islands, along with 27 carefully planned day excursions comprising trips on all of the islands. Each stop includes a description on how to approach a site and where to park with GPS locations provided. The book covers all the spectacular features of the islands, including active ocean island volcanoes whose origins are linked to a hot spot or plume causing anomalously hot mantle material to intrude the African plate, submarine volcanic sequences uplifted inside the islands, sub- aerial shield volcanoes, and the remains of giant lateral collapses. Through its clearly written and richly color-illustrated introduction and field guide, this book is essential reading for geologists who visit the Canary Islands, one of the largest and most fascinating active volcanic systems in Europe.

Vesuvius, Campi Flegrei, and Campanian Volcanism communicates the state-of-the-art scientific knowledge on past and active volcanism in an area characterized by elevated risk due to high-density population. Eruptions, lahars and poisonous gas clouds have killed many thousands of people over recorded history, but volcanoes have given people some of the most fertile soil known in agriculture. The research presented in this book is useful for policymakers and researchers from these and other countries who are looking for risk assessment and volcanic evolution models they can apply to similar situations around the world. Naples and its surrounding area, in particular, the area situated between Vesuvius and the Campi Flegrei volcanic area has a population in excess of 4 million people. The volcanic areas that have similarly large populations in proximity to dormant, but hazardous volcanoes, i.e., Indonesia and Central America can also benefit from this work.

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."
