| Research Abstract |
Characteristics of crustal deformation due to Amur plate motion and seismological structure of crust and upper mantle in far eastern Russia, Japan Sea and northwestern Pacific had been clarified from original geophysical data from international GPS and seismological observation network operated by this research project. Clear coseismic and postseismic deformation associated with the 2011 M9.0 Tohoku earthquake was recognized. These facts suggested that geodynamic effects related to subdution process along Kuril, Japan trenches and Nankai trough should be examined for detection of Amur plate motion and building tectonic frame in northeastern Asia.
