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 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.

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.

Seismic interferometry is an exciting field in geophysics utilising multiple scattering events to provide unprecedented views of the Earth's subsurface. This is a comprehensive book describing the theory and practice of seismic interferometry with an emphasis on applications in exploration seismology. Exercises are provided at the end of each chapter, and the text is supplemented by online MATLAB codes that illustrate important ideas and allow readers to generate synthetic traces and invert these to determine the Earth's reflectivity structure. Later chapters reinforce these principles by deriving the rigorous mathematics of seismic interferometry. Incorporating examples that apply interferometric imaging to synthetic and field data, from applied geophysics and earthquake seismology, this book is a valuable reference for academic researchers and oil industry professionals. It can also be used to teach a one-semester course for advanced students in geophysics and petroleum engineering.

Fundamentals of Seismic Wave Propagation, published in 2004, presents a comprehensive introduction to the propagation of high-frequency body-waves in elastodynamics. The theory of seismic wave propagation in acoustic, elastic and anisotropic media is developed to allow seismic waves to be modelled in complex, realistic three-dimensional Earth models. This book provides a consistent and thorough development of modelling methods widely used in elastic wave propagation ranging from the whole Earth, through regional and crustal seismology, exploration seismics to borehole seismics, sonics and ultrasonics. Particular emphasis is placed on developing a consistent notation and approach throughout, which highlights similarities and allows more complicated methods and extensions to be developed without difficulty. This book is intended as a text for graduate courses in theoretical seismology, and as a reference for all academic and industrial seismologists using numerical modelling methods. Exercises and suggestions for further reading are included in each chapter.

GNSS Seismogeodesy: Theory and Applications combines GNSS and seismology theory and applications to offer both disciplines the background information needed to combine forces. It explores the opportunities for integrating GNSS and seismometers, as well as applications for earthquake and tsunami early warning applications. The book allows seismologists to better understand how GNSS positions are computed and how they can be combined with seismic data and allows geodesists to better understand how to apply GNSS to monitoring of crustal motion. This book is a valuable reference for researchers and students studying the interdisciplinary connection between GNSS geodesy and strong-motion seismology. It will also be ideal for anyone working on new approaches for monitoring and predicting geologic hazards.

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.

Deep earthquakes (earthquakes with origins deeper than 60 km) are of scientific importance and account for approximately one-quarter of all earthquakes. They are occasionally very large and damaging yet provide much of the data that constrain our knowledge of Earth structure and dynamics. This book opens with an explanation of what deep earthquakes are, their significance to science and how they were first discovered. Later chapters provide a description of deep earthquake distribution and clustering in both time and space; a review of observations about source properties; and a discussion of theories for the origin of deep earthquakes. The book concludes with a comprehensive literature review of terrestrial and lunar deep seismicity. Deep Earthquakes presents a comprehensive, topical, historical, and geographical summary of deep earthquakes and related phenomena. It will be of considerable interest to researchers and graduate students in the fields of earthquake seismology and deep Earth structure.

This is a major, definitive, landmark study of the young volcanoes of eastern Australia and parts of New Zealand. It deals with the rock types and origin of the volcanoes as well as the inclusions of the upper mantle and lower-crustal rocks found in the volcanic deposits. Fifty-nine authors contribute a wide range of chapters dealing with the significance of the volcanoes, the insights the area offers about the nature and origin of the earth's crust and the mantle beneath, and the geological evolution of eastern Australia and New Zealand over the last 70-80 million years. This will be an important reference book for geoscientists in general, but particularly to those involved in the fields of volcanology, geology, goechemistry, geophysics and tectonics.

First published in 1924, this classic volume details the history of British earthquakes from the year 974 to the beginning of the twentieth century. Building on material laid out in his 1912 volume The Origin of British Earthquakes, Charles Davison based his method of investigation on the theory that earthquakes were the results of successive steps in the growth of faults. Using a modification of the well-known Rossi Forel scale, and with reference to the latest scientific studies of his time, he compiled a catalogue of all known British earthquakes. Davison was at pains to include only those earthquakes that were undoubtedly British, omitting many disturbances which had been doubtfully placed in other British lists of his time. His aim was to trace the zones in which crust-changes occurred and where the faults were still live, and to uncover some of the laws that govern the growth of faults. Additionally, Davison included a chapter describing 'Extra-British' earthquakes, examining disturbances felt in Britain that originated in Ireland, the Channel Islands, Norway, and as far away as Lisbon. His concluding chapters address the sound phenomena, distribution, and origin of different types of earthquakes.

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.

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."

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.

Covering a key connection between geological processes and life on Earth, this multidisciplinary volume describes the effects of volcanism on the environment by combining present-day observations of volcanism and environmental changes with information from past eruptions preserved in the geologic record. The book discusses the origins, features and timing of volumetrically large volcanic eruptions; methods for assessing gas and tephra release in the modern day and the palaeo-record; and the impacts of volcanic gases and aerosols on the environment, from ozone depletion to mass extinctions. The significant advances that have been made in recent years in quantifying and understanding the impacts of present and past volcanic eruptions are presented and review chapters are included, making this a valuable book for academic researchers and graduate students in volcanology, climate science, palaeontology, atmospheric chemistry, and igneous petrology.

For months in early 1980, scientists, journalists and ordinary people listened anxiously to rumblings in the long quiescent volcano Mount St. Helens. Still, when a massive explosion took the top off the mountain, no one was prepared. Fifty-seven people died and the lives of many others were changed forever. Steve Olson interweaves history, science and vivid personal stories to portray the disaster as a multi-faceted turning point. Powerful economic, political and historical forces influenced who died when the volcano erupted. The eruption of Mount St. Helens transformed volcanic science, the study of environmental resilience and our perceptions of how to survive on an increasingly dangerous planet.

Modern plate tectonic theory, the development of earthquake prediction and the mitigation of earthquake hazards are based on the study of earthquakes during the twentieth century. Investigation of earthquakes over a much longer period, although in no way invalidating the global importance of plate tectonics, shows that patterns of seismic activity do change with time and that areas of intense seismic activity in the historical past are often gaps of earthquake activity today. This study of the historical seismicity of Iran over the last thirteen centuries not only shows this quite clearly but also reveals a long-term tectonic pattern which is different from that deduced from short-term observations. The historical data provides the basis for the development of earthquake prediction models and for long-term earthquake hazard assessment. This book will be of equal interest to earth scientists, seismologists, historical geographers and orientalists.

A careful and intensive study of historical sources and a review of the instrumental data of this century have led to this detailed catalogue of earthquakes. Egypt, Arabia, the Red Sea region and the surrounding areas of Libya, Sudan and Ethiopia are studied from the earliest times to the present day. Each earthquake is described as fully as possible from the available data, and is analysed in a geographical and historical context. The completeness of the earthquake catalogue over time is analysed and the range of sources and problems associated with the scrutiny of historical sources is discussed. The information is then placed in a geophysical framework.

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.

Bridging the gap between introductory textbooks and advanced monographs, this book provides the necessary mathematical tools to tackle seismological problems and demonstrates how to apply them. Including student exercises, for which solutions are available on a dedicated website, it appeals to advanced undergraduate and graduate students. It is also a useful reference volume for researchers wishing to "brush up" on fundamentals before they study more advanced topics in seismology.

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.

The two volumes of The Seismic Wavefield are a comprehensive guide to the understanding of seismograms in terms of physical propagation processes within the Earth. The focus is on the observation of earthquakes and man-made sources on all scales, for both body waves and surface waves. Volume I provides a general introduction and a development of the theoretical background for seismic waves. Volume II looks at the way in which observed seismograms relate to the propagation processes. Volume II also discusses local and regional seismic events, global wave propagation, and the three-dimensional Earth.

Serendipity placed David Johnston on Mount St. Helens when the volcano rumbled to life in March 1980. Throughout that ominous spring, Johnston was part of a team that conducted scientific research that underpinned warnings about the mountain. Those warnings saved thousands of lives when the most devastating volcanic eruption in U.S. history blew apart Mount St. Helens, but killed Johnston on the ridge that now bears his name. Melanie Holmes tells the story of Johnston's journey from a nature-loving Boy Scout to a committed geologist. Blending science with personal detail, Holmes follows Johnston through encounters with Aleutian volcanoes, his work helping the Portuguese government assess the geothermal power of the Azores, and his dream job as a volcanologist with the U.S. Geological Survey. Interviews and personal writings reveal what a friend called "the most unjaded person I ever met," an imperfect but kind, intelligent young scientist passionately in love with his life and work and determined to make a difference.
