Shallow-focus seismic activity in the rear of Japan-Sakhalin insular arc and its possible tectonic nature
On the base of analysis of data from different seismic bulletins for the Japan Sea basin the most comprehensive unified catalogue of earthquake with magnitude M > 3,0 and depths h < 60 km for the period 1975-2010 has been prepared for the first time. Maps of epicenter of events for the...

Geofizicheskiy Zhurnal| Summary: | On the base of analysis of data from different seismic bulletins for the Japan Sea basin the most comprehensive unified catalogue of earthquake with magnitude M > 3,0 and depths h < 60 km for the period 1975-2010 has been prepared for the first time. Maps of epicenter of events for the four intervals (0-10, 11-20, 21-30 and 31-60 km) and three sub-latitude sections are plotted. Structural peculiarities have been considered and possible tectonic nature of seismic zone along submarine margin or borderland of the Japan-Sakhalin island arc: regional uplift, rather mega-duplex fracture of compression faults, caused by crustal sliding at the rear of frontal deep thrust. |
