Earthquake prediction studies based on electromagnetic techniques have drawn considerable global attention in recent years. This technique is based on ground and satellite based monitoring of electromagnetic signals in a broad frequency range between DC and VHF employing variety of sensors. Definite earthquake precursors have been reported from these experiments. Besides the above, ionospheric perturbations and geochemical anomalies have also been reported prior to the occurrence of the earthquakes. This book contains some important research output in the above fields obtained by well-known researchers. More precisely, there are descriptions on recent progress in VAN method, anomalies in ULF/VLF signals, ionospheric parameters and Schumann resonance etc. The book also includes one topic not related to seismicity which deals with space weather, Trimpi phenomena, and neural network approach to TSP solutions etc.

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.

Geophysics and Geochemistry is a component of Encyclopedia of Earth and Atmospheric Sciences in the global Encyclopedia of Life Support Systems (EOLSS), which is an integrated compendium of twenty one Encyclopedias. Geophysics and Geochemistry are two closely intertwined and collaborating branches of Earth’s sciences. The content of the Theme on Geophysics and Geochemistry is organized with state-of-the-art presentations covering eight main topics: Foundations of Geophysics and Geochemistry; Geophysical Systems; Seismology and Volcanology; Geomagnetism and Geoelectricity; Aeronomy and Magnetosphere; Gravimetry; Geochemistry and Cosmochemistry; Planetology – Comparative Planetology of Earth-like Planets and Astrobiology which are then expanded into multiple subtopics, each as a chapter. These three volumes are aimed at the following a wide spectrum of audiences from the merely curious to those seeking in-depth knowledge: University and College students Educators, Professional practitioners, Research personnel and Policy analysts, managers, and decision makers and NGOs

NATO Advanced Research Workshop “The Black Sea: Strategy for Addressing its Energy Resource Development and Hydrogen Energy Problems” was held in order to evaluate the Black Sea Region’s environment, discuss the ways and means of protecting it, and to evaluate the methods of production of the energy carrier, hydrogen. Papers presented at the workshop, proposed various methods of hydrogen production from the hydrogen sulfide, from marine macro algae and other bacteria, storage and utilization of hydrogen, oil spills and pollutants in the Black Sea, degradation of the sea and the land around the region, and ways and means of protecting the environment. The workshop participants unanimously expressed the need to establish close cooperation amongst the Region’s countries regarding the development of its energy resources, and at the same time protecting its environment. These recommendations have been put together in the Batumi Manifesto. This book entitled “Black Sea Energy Resource Development and Hydrogen Energy Problems” puts together the papers presented at the workshop, starting with the Batumi Manifesto. This valuable volume should be in the libraries of all the scientists, engineers, environmentalists, economists and decision makers involved in the development of the Black Sea Region and in the introduction of clean and abundant Hydrogen Energy.

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).

The participation of such diverse scientific and technical disciplines as meteorology, astronomy, atmospheric electricity, ionospheric and magnetospheric physics, electromagnetic wave propagation, and radio techniques in the research of atmospherics means that results are published in scientific papers widely spread throughout the literature. This Handbook collects the latest knowledge on atmospherics and presents it in two volumes. Each chapter is written by an expert in his or her field. Topics include the physics of thunderclouds, thunder, global atmospheric electric currents, biological aspects of sferics, and various space techniques for detecting lightning within our own atmosphere as well as in the atmospheres of other planets. Up-to-date applications and methodology are detailed. Volumes I and II offer a comprehensive discussion that together will serve as an important resource for practitioners, professionals, and students alike.

The study of earthquakes plays a key role in order to minimize human and material losses when they inevitably occur. Chapters in this book will be devoted to various aspects of earthquake research and analysis. The different sections present in the book span from statistical seismology studies, the latest techniques and advances on earthquake precursors and forecasting, as well as, new methods for early detection, data acquisition and interpretation. The topics are tackled from theoretical advances to practical applications.
