This book introduces a methodology for solving the seismic inverse problem using purely numerical solutions built on 3D wave equations and which is free of the approximations or simplifications that are common in classical seismic inversion methodologies and therefore applicable to arbitrary 3D geological media and seismic source models. Source codes provided allow readers to experiment with the calculations demonstrated and also explore their own applications.

The special natural conditions in Iceland as well as high level technology, were the basis for multidisciplinary and multinational cooperation for studying crustal processes, especially processes ahead of large earthquakes. This work leads to new innovative results and real time warnings which are described in the book. The results obtained in Iceland are of significance for earthquake prediction research worldwide.

Anja Schmidt's thesis is a unique and comprehensive evaluation of the impacts of tropospheric volcanic aerosol on the atmosphere, climate, air quality and human health. Using a state-of-the-art global microphysics model, the thesis describes and quantifies the impact of volcanic sulphur emissions on global aerosol, clouds and the radiative forcing of climate. The advanced model enables the first ever estimate of the impact of the emissions on aerosol microphysical properties such as particle number concentrations and sizes, and therefore a considerably improved ability to quantify the climate and air quality effects. There are several important discoveries in this thesis. Firstly, it is shown that continuously degassing volcanoes exert a major effect on global clouds and climate. Secondly, the impact of the 1783 Laki eruption in Iceland is re-examined to show that this long-lasting flood lava eruption would have had major effects on clouds and climate. Thirdly, by combining her research on volcanism, atmospheric science and epidemiology, she shows that a present-day Laki-like eruption would seriously affect European air quality and cause over 100000 premature deaths in the first year.

The mechanisms of magma movement, chemical differentiation and physical development, are derived from the geochemistry of igneous rocks, and from studying exposures of deep magmatic systems that have since solidified and been uplifted and exposed at the Earth's surface. The Ferrar Magmatic System of the McMurdo Dry Valleys in Antarctica provides an unparalleled example of a complete magmatic-volcanic system exposed in unprecedented detail. This book provides a unique and usual three-dimensional detailed examination of this system, providing insight into many magmatic processes normally unobservable, in particular how basaltic magma moves upwards through the crust, how it entrains, carries and deposits loads of crystals from great depths, and how this all contributes to Earth's evolution. Providing an explanation of how magmatic systems operate and how igneous rocks form, this is an invaluable resource ideal for researchers and graduate students in magma physics, igneous petrology, volcanology, and geochemistry.

As evidenced dramatically and tragically in 2011 alone,earthquakes cause devastation and their consequences in terms of human suffering and economic disaster can last for years or even decades. The VAN method of earthquake prediction, based on the detection and measurement of low frequency electric signals called Seismic Electric Signals (SES), has been researched and evaluated over 30 years, and now constitutes the only earthquake prediction effort that has led to concrete successful results. This book recounts the history of the VAN method, detailing how it has developed and been tested under international scrutiny. Earthquake Prediction by Seismic Electric Signals * describes, step by step, the development of the VAN method since 1981; * explains both the theoretical model underpinning the research and the physical properties of SES; * analyzes the SES recordings and the prediction for each major earthquake in Greece over the last 25 years; * introduces a new time domain, natural time, which plays a key role in predicting impending catastrophic events.

Shared Risk is an unparalleled study of how communities at risk respond to major hazards. This major new book explores the elastic boundary between structure and flexibility that enables modern organizations to function effectively under uncertain, dynamic conditions.

Through a comprehensive analysis of earthquake case studies, Louise Comfort shows how communities and organizations cope with dynamic and unpredicted events. Drawing upon the concept of shared risk, she examines the self-organizing processes by which communities act in their own interest to mitigate and reduce risk. Placing shared risk within a theoretical framework consistent with disaster situations, Professor Comfort presents policy-relevant analysis of disaster response systems.

The practical, theoretical and methodological issues involved in the study of shared risk are addressed in the first part of the book which also sets this problem in the global context of seismic risk. This is followed by comparative analysis of eleven different case studies of rapidly evolving response systems following earthquakes. The final part of the volume compares different classes of response systems and presents a preliminary model for a sociotechnical system to mitigate seismic risk and facilitate response when earthquakes occur.

Examining the relationship between information, action and theory and theories of organizational adaptation, this book will be applicable to a wide range of organizational change efforts, as well as being a strong and distinctive contribution to the literature on seismic policy and crisis management.

Especially in recent years, seismology has attracted much interest from the general public as well as from news agencies. The reasons for this are partly con- nected with recordings of large explosions (nuclear tests), partly related to earthquake catastrophes. This interest and the questions which people have asked us for the past years have to a certain extent served as a sti- mulus in the preparation of this book.

This book places Oakland's public policy response (nine major ordinances) to building damage suffered in the 1989 Loma Prieta earthquake in a full historical and intergovernmental context. Using a combined non-decision making and advocacy coalition approach, the book demonstrates how and why hazardous-structure abatement was kept off the local political agenda prior to the Loma Prieta disaster. The book then demonstrates how and why city government in Oakland became proactive on the problem of earthquake-damaged and, more importantly, earthquake-vulnerable buildings in general after the disaster.

There are many general geophysical textbooks dealing with the subject of seismic refraction. As a rule, they treat the principles and broad aspects ofthe method comprehensively but problems associated with engineering seismics at shallow depths are treated to a lesser extent. The intention of this book is to emphasize some practical and theoretical aspects of detailed refraction surveys for civil engineering projects and water prospecting. The book is intended for students of geophysics, professional geophysicists and geologists as well as for personnel who, without being directly involved in seismic work, are planning surveys and evaluating and using seismic results. The latter category will probably find Chapters 1, 5 and 6 of most interest. Interpretation methods, field work and interpretation of field examples constitute the main part of the book. When writing I have tried to concentrate on topics not usually described in the literature. In fact, some discussions on interpretation and correction techniques and on sources of error have not been published previously. The field examples, which are taken from sites with various geological conditions, range from simple to rather complicated interpretation problems. Thanks are due to A/S Geoteam (Norway), Atlas Copco ABEM AB (Sweden), BEHACO (Sweden) and the Norwegian Geotechnical Institute for allowing me to use field examples and certain data from their investigations. I should particularly like to thank Professor Dattatray S. Parasnis of the University of Luleii (Sweden) for revising the manuscript and for his numerous invaluable suggestions.

Intraplate earthquakes occur away from tectonic plate boundaries: their locations are difficult to predict, risking huge damage and loss of life. The 2001 Bhuj earthquake (featured in this book) was the largest intraplate earthquake for three decades and has provided unique insight into these events. This cutting-edge book brings together research from international leading experts in the field. Each chapter provides a comprehensive review of these earthquakes in a different global location, ranging from Australia, China, India and the Sea of Japan, to Western Europe, Brazil, New Madrid (Central USA), and Eastern Canada. They explore similarities and differences between regional features and the mechanical models required to explain them, as well as assessing geophysical techniques used to investigate them. Providing the first global overview of intraplate earthquakes, this is an essential book for academic researchers and professionals in seismology, tectonics, tectonophysics, geodesy, structural geology, earthquake dynamics, geophysics, and structural engineering.

This book deals with the theory and the applications of a new time domain, termed natural time domain, that has been forwarded by the authors almost a decade ago (P.A. Varotsos, N.V. Sarlis and E.S. Skordas, Practica of Athens Academy 76, 294-321, 2001; Physical Review E 66, 011902, 2002). In particular, it has been found that novel dynamical features hidden behind time series in complex systems can emerge upon analyzing them in this new time domain, which conforms to the desire to reduce uncertainty and extract signal information as much as possible. The analysis in natural time enables the study of the dynamical evolution of a complex system and identifies when the system enters a critical stage. Hence, natural time plays a key role in predicting impending catastrophic events in general. Relevant examples of data analysis in this new time domain have been published during the last decade in a large variety of fields, e.g., Earth Sciences, Biology and Physics. The book explains in detail a series of such examples including the identification of the sudden cardiac death risk in Cardiology, the recognition of electric signals that precede earthquakes, the determination of the time of an impending major mainshock in Seismology, and the analysis of the avalanches of the penetration of magnetic flux into thin films of type II superconductors in Condensed Matter Physics. In general, this book is concerned with the time-series analysis of signals emitted from complex systems by means of the new time domain and provides advanced students and research workers in diverse fields with a sound grounding in the fundamentals of current research work on detecting (long-range) correlations in complex time series. Furthermore, the modern techniques of Statistical Physics in time series analysis, for example Hurst analysis, the detrended fluctuation analysis, the wavelet transform etc., are presented along with their advantages when natural time domain is employed.

Tsunamis are primarily caused by earthquakes. Under favourable geological conditions, when a large earthquake occurs below the sea bed and the resultant rupture causes a vertical displacement of the ocean bed, the entire column of water above it is displaced, causing a tsunami. In the ocean, tsunamis do not reach great heights but can travel at velocities of up to 1000 km/hour. As a tsunami reaches shallow sea depths, there is a decrease in its velocity and an increase in its height. Tsunamis are known to have reached heights of several tens of meters and inundate several kilometres inland from the shore. Tsunamis can also be caused by displacement of substantial amounts of water by landslides, volcanic eruptions, glacier calving and rarely by meteorite impacts and nuclear tests in the ocean.
In this SpringerBrief, the causes of tsunamis, their intensity and magnitude scales, global distribution and a list of major tsunamis are provided. The three great tsunamis of 1755, 2004 and 2011are presented in detail. The 1755 tsunami caused by the Lisbon earthquake, now estimated to range from Mw 8.5 to 9.0, was the most damaging tsunami ever in the Atlantic ocean. It claimed an estimated 100,000 human lives and caused wide-spread damage. The 2004 Sumatra Andaman Mw 9.1 earthquake and the resultant tsunami were the deadliest ever to hit the globe, claiming over 230,000 human lives and causing wide-spread financial losses in several south and south-east Asian countries. The 2011 Mw 9.0 Tohoku-Oki earthquake and the resultant tsunami were a surprise to the seismologists in Japan and around the globe. The height of the tsunami far exceeded the estimated heights. It claimed about 20,000 human lives. The tsunami also caused nuclear accidents. This earthquake has given rise to a global debate on how to estimate the maximum size of an earthquake in a given region and the safety of nuclear power plants in coastal regions. This Brief also includes a description of key components of tsunami warning centres, progress in deploying tsunami watch and warning facilities globally, tsunami advisories and their communication, and the way forward.

The reasons for writing this book are very simple. We use and teach com puter aided techniques of mathematical simulation and of pattern recogni tion. Life would be much simpler if we had a suitable text book with methods and computer programmes which we could keep referring to. Therefore, we have presented here material that is essential for mathematical modelling of some complex geological situations, with which earth scientists are often confronted. The reader is introduced not only to the essentials of computer modelling, data analysis and pattern recognition, but is also made familiar with the basic understanding with which they can plunge into when solving related and more complex problems. This book first makes a case for seismic stratigraphy and then for pattern recognition. Chapter 1 provides an extensive review of applications of pattern recognition methods in oil exploration. Simulation procedures are presented with examples that are fairly simple to understand and easy to use on the computer. Several geological situations can be formulated and simulated using the Monte Carlo method. The binary lithologic sequences, discussed in Chapter 2, consist of alternating layers of any two of sand, shale and coal."

The M8.0 Wenchuan Earthquake occurred in China on May 12, 2008, killing over 69,000 people and displacing millions from their homes. This was one of the most catastrophic natural disasters on record. This book includes 5 chapters describing the tectonic setting and historical earthquakes around the Chuan-Dian region, the nucleation of the Wenchuan earthquake, occurrence and aftershocks. The field observations of earthquake induced surface fractures and building damage, form a major and special part of this book and include a large number of digital photos with accompanying explanantions.

Earthquake fault zones exhibit hierarchical damage and granular structures with evolving geometrical and material properties. Understanding how repeated brittle deformation form the structures and how the structures affect subsequent earthquakes is a rich problem involving coupling of various processes that operate over broad space and time scales. The diverse state-of-the-art papers collected here show how insight can come from many fields including statistical physics, structural geology and rock mechanics at large scales; elasticity, friction and nonlinear continuum mechanics at intermediate scales; and fracture mechanics, granular mechanics and surface physics at small scales. This volume will be useful to students and professional researchers from Earth Sciences, Material Sciences, Engineering, Physics and other disciplines, who are interested in the properties of natural fault zones and the processes that occur between and during earthquakes.

In recent years, large earthquakes in the circum-Pacific region have repeatedly demonstrated its particular vulnerability to this potentially devastating natural hazard, including the M 9.2 Northern Sumatra earthquake and tsunami of 2004 which resulted in the deaths of nearly 300,000 people. In the late-1990s, major advancements in seismic research greatly added to the understanding of earthquake fault systems, as large quantities of new and extensive remote sensing data sets provided information on the solid earth on scales previously inaccessible were integrated with a combination of innovative analysis techniques and advanced numerical and computational methods implemented on high-performance computers. This book includes a variety of studies that focus on the modeling of tsunamis and earthquakes, both large-scale simulation and visualization programs, as well as detailed models of small-scale features. Particular attention is paid to computational techniques, languages, and hardware that can be used to facilitate data analysis, visualization, and modeling. Also included are studies of several earthquake forecasting techniques and associated comparisons of their results with historic earthquake data. Finally, the volume ends with theoretical analyses of statistical properties of seismicity by internationally recognized experts in the field. This volume will be of particular interest to researchers interested in the multiscale simulation and visualization of large earthquakes and tsunamis.

This, the Hiroshi Wakita Volume III is a special publication brought out by Springer to honor Professor Wakita for his contributions to science. These have been closely linked with one of the major objectives of this 2008 International Year for the Earth Planet. Reducing natural risks in active tectonic and volcanic environments by searching for and detecting early warning signatures related to earthquakes and volcanic eruptions has been a major research goal for Hiroshi Wakita.

Seismology is rated the Queen of Earth Sciences due to its ability to provide detailed structural information bearing on the Earth interior and on-going dynamic processes. This is due to the advanced theoretical foundation of seismology and the extensive cooperation among seismologists on recording and disseminating of data worldwide. In contrast, some 40 years ago seismology was a backward science and hence funding was poor.

This abruptly changed with the political interest in seismology as the principal tool for monitoring compliance with a potential Comprehensive Nuclear Test Ban treaty (CTBT) banning nuclear testing in any environment.

Major countries like USA, UK and USSR launched large-scale research programs including deployment of modern seismograph stations and arrays and these developments are detailed in the book for CTBTO (UN), IRIS (USA), MedNet (Italy), Geofon (Germany) and the tiny Karelia network, NW Russia. Station and network operations require near real time record analysis and topics dealt with here are 2-D signal detector, epicenter location and earthquake monitoring. Balkan is seismically the most active part of Europe due to multiple plate interactions in the Aegean Sea. The tectonic evolution and on-going geodynamic deformations are described in 2 articles. Earthquake hazard analysis and topographic site effects are discussed and likewise large earthquake hazards in the Aegean and the Marmara seas relate to practical applications of such procedures. Foremost; the book gives a good account of past, present and likely future seismological developments in Balkan countries and various kinds of network operations on local to global scales.

During the last decade, the state of the art in Earthquake Engineering Design and Analysis has made significant steps towards a more rationale analysis of structures. Scientists have long recognized that earthquake design is guided by displacements and deformations rather than forces. However due to the historical background of structural engineers in static analyses, effects of earthquake on structures have been viewed as forces acting on the structures. All presently available design building codes are developed along these lines. Our knowledge of ground motion characteristics, earthquake geotechnical engineering, structural behaviour (design and numerical analyses) and model tests have advanced to a point where it is possible to anticipate a significant move from force based design approaches to displacements based design approaches. Although displacement based analyses constitute the kernel of most research programs, they have not yet been incorporated in the state of practice.

The purpose of the book is to review the fundamentals of displacement based methods, starting from engineering seismology, earthquake geotechnical engineering, to focus on design, analysis and testing of structures with emphasis on buildings and bridges.

The most powerful volcanoes in the Solar System are not on Earth, but on Io, a tiny moon of Jupiter. Whilst Earth and Io are the only bodies in the Solar System to have active, high-temperature volcanoes, those found on Io are larger, hotter, and more violent. This, the first book dedicated to volcanism on Io, contains the latest results from Galileo mission data analysis. As well as investigating the different styles and scales of volcanic activity on Io, it compares these volcanoes to their contemporaries on Earth. The book also provides a background to how volcanoes form and how they erupt, and explains quantitatively how remote-sensing data from spacecraft and telescopes are analysed to reveal the underlying volcanic processes. This richly illustrated book will be a fascinating reference for advanced undergraduates, graduate students and researchers in planetary sciences, volcanology, remote sensing and geology.

Digital signal processing has become an integral part of observational seismology. Seismic waveforms and the parameters commonly extracted from them are strongly influenced by the effects of numerous filters, both within the earth and within the recording system. With the advent of numerous software tools for the processing of digital seismograms, seismologists have unprecedented power in extracting information from seismic records. These tools are often based on sophisticated theoretical aspects of digital signal processing which, to be used properly, need to be understood. This book is aimed at observational seismologists and students in geophysics trying to obtain a basic understanding of those aspects of digital signal processing that are relevant to the interpretation of seismograms. It covers the basic theory of linear systems, the design and analysis of simple digital filters, the effect of sampling and A/D conversion, the calculation of 'true ground motion', and the effects of seismic recording systems on parameters extracted from digital seismograms. It contains numerous examples and exercises together with their solutions.
