structures changes notably to an orientation subparallel to the trench axis, N30°E.
The Daiichi-Kashima Seamount is cut by a large normal fault parallel to the trench
axis into two blocks, the western half of which is nearly vertically offset from the
eastern block by about 1,600 m (Kobayashi et al. 1987 ).
