Fault kinematics of Sakhalin Island based on geological and seismological data
The paper presents a tectonic map of Sakhalin Island showing digitized faults derived from 1:1,000,000 scale tectonic maps and identified by geological surveys (detailed on 1:200,000 and 1:50,000 scale maps). The structural geological data on the kinematics of faults have been compared with seismo...

| description | The paper presents a tectonic map of Sakhalin Island showing digitized faults derived from
1:1,000,000 scale tectonic maps and identified by geological surveys (detailed on 1:200,000 and 1:50,000 scale
maps). The structural geological data on the kinematics of faults have been compared with seismological data on
the earthquake focal mechanisms. A reasonable correspondence of these data has been obtained. The
predominant kinematic type of faults is thrust/throw in the southern and northern parts of Sakhalin Island. In the
central part of Sakhalin, a mixing of fault kinematic types is observed, mainly thrust faults with rare normal and
strike-slip faults. Two uninformative zones have been identified with virtually no data on both structural geology
and seismology. The earthquake focal mechanisms with a strike-slip component are dominant at their boundaries. |
