Sensitive zones of the Earth’s crust as a manifestation of dynamics of the interaction of blocks

Peculiarities of geophysical fields in interblock contact zones may serve as good indicators of such processes and supplement direct measurements of deformation. he study of high-amplitude effects in sensitive zones showed that such effects are inevitably followed by strong earthquakes over the surrounding vast area. The most intense phase of such effects is usually observed within some days or months prior to the earthquake at an epicentral distance of 70560 km.
