Visualization of earthquake sources on images of the underlying surface

Article preview

In the potential field of mechanical stresses of the origin, anomalies of characteristics of the lithosphere are observed. As a consequence of anomalies, the parameters of electromagnetic field of both own upward radiation and the light flux reflected from the surface of the source are changed. By software processing of images, the areas of foci are reliably distinguished above the background level.

Dynamic precursors of earthquakes

Article preview

A physical model of earthquake source formation as a statically unstable system with several degrees of freedom has been proposed; the mechanism of the process has been considered and a mathematical model of its description has been substantiated, which makes it possible to identify the main physical components for space monitoring and earthquake forecasting. It has been established that before realization of dynamic phenomenon there is rocking of rock volume (source zone) with propagation of ultra-low (period 3.5-4.5 h) lithospheric waves, which parameters can be used to determine hypocenter, magnitude and time of impact.
