RIGIDITY OF TECTONIC STRUCTURES IN THE CENTRAL EAST EUROPEAN PLATFORM

Abstract

In this paper, we present the results of experimental measurement of the mechanical rigidity of the Oka sector of the deep Nelidovo–Ryazan tectonic structure (NRTS) and auxiliary faults of order II. The kn and ks values were based on recording nonlinear effects of the propagation of low-amplitude seismic waves across the mentioned fracture. In the NRTS, kn = 0.05–0.19 MPa/mm; ks = 0.012–0.034 MPa/mm. In fractures of order II, these parameters are equal to 0.28–1.0 and 0.08–0.29 MPa/mm, respectively.
