Tectonophysical digital database of Sakhalin Island

The paper summarizes the results of field tectonophysical studies of Sakhalin Island conducted by different researchers at different times. Information about the main characteristics of the stress-strained state of the upper part of the Earth's crust (principal stress axes, stress state type, Lode–Nadai coefficient, bedding planes) was obtained as a result of computations using methods of cataclastic analysis of discontinuous displacements, structural-paragenetic, kinematic, conjugate pairs of faults. The input data for the calculations were the materials of field measurements of fracturing, slickensides and structural patterns. The results obtained in the present and previous works on Sakhalin field tectonophysical research are represented in summary tables that include data on local stress states for 264 observation points. The results are incorporated to GIS, the Isoline GIS software is used for the database management system.
