Studying deep structure of the South Sakhalin by seismic tomography
For the first time we have constructed cross sections in seismic velocities of primary waves down to the depth of 30 km for the South Sakhalin using the method of seismic tomography. These seismic models were used for updating the location of local earthquake hypocenters happened in the south part of the Sakhalin. Some of the velocity model anomalies show good correlation with major fault zones and geologic structure of the region. Obtained results can be used for refining the geologic structure of Sakhalin and getting better idea about its tectonic origination and development.
