摘要

In a surface layer of a massif or in a control medium brought in contact with the massif an electromagnetic field is established, and series of amplitudes of the field magnetic component or series of other electromagnetic field parameters are periodically measured, the parameters being a function of the electromagnetic parameters of the medium being irradiated. The measurements are made in a circle of up to 5 m radius with a center in a profile point, whereafter the results of measurements made in different times are compared and the contemporary geodynamic movements are evaluated from the variation of a characteristic of an azimuth anisotropy of the electromagnetic parameter of the medium being irradiated. From the nature of the variations of the characteristic there is determined a type of rock deformation associated with the contemporary geodynamic movements, and from the speed of these variations there is determined the intensity of the contemporary geodynamic movements.
