Outline of Final Research Achievements

Seismic and GNSS observation had been carried out in northeastern Asia with Russian institutions. Significant regional post-seismic crustal deformation has been detected. Postseismic displacements exceeded co-seismic one in Prymorie stations. Detailed seismic tomographic image using broadband seismograms clearly detected seismic velocity structure beneath Japan Sea. Viscoelastic structure estimation using geodetic and seismic information was performed. Misfit between calculated and observed postseismic displacements might request to construct more complex structure. Our model allow to estimate regional postseismic signals due to historical past great earthquakes in Japan Islands. Estimated viscoelastic parameters had predicted great subduction earthquakes around Japan generated regional and long-term deformation in northeast Asia. This fact suggested current crustal deformation field in continent has been strongly affected by distant subduction earthquakes.
