We determined the deep seismic structure of the seismogenic plate boundary zone of off-Sanriku, the northern part of the Japan Trench inner slope area. Travel time data from aftershocks of the 1994 Far-off Sanriku earthquake ( M=7.5) recorded both by ocean bottom seismographs and the local land seis...
