The latest achievements of earthquake prediction via radio communication systems, by the world's leading authority Prof. Hayakawa is one of the world leaders in the field of seismo-electromagnetics for EQ prediction and this area of research is still evolving Presents the fundamentals of radio communications and radio propagation, using the radio noises and propagation anomalies as a precursor of earthquakes Considers the combination of different kinds of seismogenic electromagnetic signals of both natural and artificial character Timely topic following the recent sequence of highly destructive earthquakes around the world

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.

One of the keystones of science is the ability to precisely and consistently forecast natural phenomena. Unfortunately, earthquake prediction research has been plagued by controversy, and it remains an outstanding problem; for a review of some of the historical challenges. Today's scientists understand earthquakes a lot better than we did even 50 years ago, but they still can't match the quake-predicting expertise of the common toad, which can detect seismic activity days in advance of a quake. As a result, most earthquake predictions are vague at best. Scientists have had more success predicting aftershocks, additional quakes following an early earthquake. These predictions are based on extensive research of aftershock patterns. Earthquake forecasting and prediction is an active topic of geological research. Geoscientists are able to identify particular areas of risk and, if there is sufficient information, to make probabilistic forecasts about the likelihood of earthquakes happening in a specified area over a specified period.This volume is packed with state-of -art information covering various methods and techniques for evaluating earthquake predictions and earthquake forecasts. This book brings a combination of basic earthquake science techniques that will make the book understandable to the non-specialist, a good assortment of data and research conclusions, and a bare-knuckles appraisal of current philosophy and strategy for prediction of earthquakes. The book includes field, laboratory, and theoretical investigations of earthquake mechanisms and fault zones. Progress in long- and intermediate-term earthquake prediction is reviewed emphasizing results from various sites.

The acronym VAN refers to Drs Varotsos, Alexopoulos and Nomicos, members of a group based in the University of Athens and led by Professor Varotsos (head of the Physics Department) which for over a decade has sought to use electric-field measurements between electrodes buried in the earth to predict earthquakes in Greece over periods of order one month or less. But is such “short-term” prediction achievable by the VAN approach (or by any other)? This book is an objective collection of the arguments for — and the counterarguments against — that approach, intended to help scientific readers arrive at their own answers to this important question, as well as to others (including that of VAN's “export” potential).

Pre-Earthquake signals are advanced warnings of a larger seismic event. A better understanding of these processes can help to predict the characteristics of the subsequent mainshock. Pre-Earthquake Processes: A Multidisciplinary Approach to Earthquake Prediction Studies presents the latest research on earthquake forecasting and prediction based on observations and physical modeling in China, Greece, Italy, France, Japan, Russia, Taiwan, and the United States. Volume highlights include: Describes the earthquake processes and the observed physical signals that precede them Explores the relationship between pre-earthquake activity and the characteristics of subsequent seismic events Encompasses physical, atmospheric, geochemical, and historical characteristics of pre-earthquakes Illustrates thermal infrared, seismo–ionospheric, and other satellite and ground-based pre-earthquake anomalies Applies these multidisciplinary data to earthquake forecasting and prediction Written for seismologists, geophysicists, geochemists, physical scientists, students and others, Pre-Earthquake Processes: A Multidisciplinary Approach to Earthquake Prediction Studies offers an essential resource for understanding the dynamics of pre-earthquake phenomena from an international and multidisciplinary perspective.
