NEW DATA ON REGULARITIES OF FAULT ACTIVATION IN THE BAIKAL RIFT SYSTEM AND THE ADJACENT TERRITORY

Abstract

Possible sources of fault activation in real time are deformation excitation waves generated by evolution of rifting and interplate motions. Spatial oscillating longitudinal–transverse migration of seismic sources in dynamic influence zones of specific faults is shown on the basis of seismic monitoring. Based on the major criterion of modern activation of faults, i.e., confinement of seismic sources to them, and concepts of earthquake generation regions, properties of modern active faults unknown previously in the study region were revealed and new data on structural regularities and geodynamic sources of activation of ruptures were obtained.
