The site of Higashidori nuclear power station is underlain by Neogene Miocene consisting of pyroclastic and sedimentary rocks. Marine terrace deposits of upper Pleistocene overlays these formations. In those Miocene the major normal faults are observed, which fracture zones have partly undergone hydrothermal alteration, mineralization and lithification during Neogene period. These features indicate that those faults are not active at least in the late Quaternary. On the other hand, in the Quaternary se...
