Abstract
Observations on Synthetic Aperture Radar (SAR) scenes of the European Remote Sensing (ERS) satellite permit a new mapping of active faults in central Japan. The analysis gives a coherent pattern of active structures resulting from a stress regime where the maximum stress algorithms component C 1 trends N110°E. This stress field is associated both with compression and with a strike-slip regime of deformation. Compression is characterized by ∼N20°E-trending reverse faults and folds axis. Strike-slip tectonics is characterized by a system of ∼N65°E dextral and ∼N145°E sinistral conjugate strike-slip faults. We have evidenced new unknown tectonic structures associated with shearing, such as active folds, push-up hills and pull-apart or releasing bend basins filled with Plio-Quaternary sediments. The emplacement of the Ontake San volcano benefits also from tectonic structures deduced from geological remote sensing results: it is rooted upon a N110°E vertical open tension fracture.
