A flight of late Quaternary marine terraces in the Tobi-shima Island, Northeast Japan, shows tilt toward the east. Uplift pattern of five paleoshorelines allows two modes of deformation to be estimated; chronic uplift marked in the southwestern part, and south-eastward tilting probably by cumulative seisimic crustal displacement.
