| Abstract: | Results are presented from a seismic refraction survey (P-S waves) carried out in different years on recent faults of North Sakhalin. Structural features of the near-surface zone of active faults with different types of tectonic motions and their imaging in seismic fields are demonstrated. Criteria for estimating the activity of the studied tectonic disruption are proposed. |
