Microseismic Sounding and Active Faults of the Kerch-Taman Region

Resumo

Abstract—The results of integrated geological and geophysical studies of active faults and deep structure of the Kerch-Taman region are presented. Data on the deep structure of potential sources of strong earthquakes determining the level of seismic hazard are obtained. Examples of the active faults, well studied on the surface, show that these structures are clearly spotted by microseismic sounding method as the displacements of contrasting layers in the section at a depth of a few km or as narrow low-velocity bodies. In the zones of the Tobechik, South Azov, and Phanagoria faults at depths of 7–12 km, high-velocity isometric inclusions are established. These segments are especially important for making ther repeated MSM measurements for seismic forecasting purposes.
