This book contains the papers selected by the Scientific Committee and represented at the XIV International Conference "Solar-Terrestrial Relations and Physics of Earthquake Precursors", which was hold at the Institute of Cosmophysical Research and Radio Wave Propagation, Far Eastern Branch of the Russian Academy of Sciences, Kamchatka. The book describes the investigation results in the fields of atmosphere, ionosphere and magnetosphere physics. Mechanisms of transformation of solar wind energy into the energy of magnetospheric-ionospheric processes, effects of the processes in the Earth core on the lower and upper atmosphere and seismo-electromagnetic, seismo-electric and seismo-acoustic effects at different frequency ranges in the Earth crust, atmosphere and ionosphere are under consideration. Modern methods for geophysical data collection, processing, transfer and exchange as well as organisation issues of seismic activity monitoring are presented. The conference "Solar-Terrestrial Relations and Physics of Earthquake Precursors" has 25 years of history. Scientists from Russia, Japan, India, France, Belarus and other countries participate in it. In a traditional way, the conference includes three sections: atmosphere physics, geophysical fields and their interactions, physics of earthquake precursors.
