Optimality and Unity of Interactions of Geophysical Fields and Waves

This article describes interaction of geophysical field of the different types. Interaction of fields means the converting of the waves energy of one type into the waves energy of another type. Using the results obtained in experiments in the Baikal rift zone by the method of vibrational sounding of adjacent "air-ice-water-earth" media, field seismo-hydroacoustic and meteo-acoustic interactions are analyzed. Such interactions must be studied due to the need to solve a number of modern environmental protection problems of predicting the geoecological impact of various man-made and natural processes as transport and industrial noise, quarry and test site explosions, etc. on the surrounding social infrastructure and natural environment. As part of the problems under consideration the results of experiments on registration at long distances of seismic waves in the ground, hydroacoustic waves in water and sound waves in the air are presented. The effect of spatial focusing of sound waves in the air, which causes high geoecological risks of infrasound impact on the surrounding social environment, is considered.
