Active fault database of Japan

What's New

2024/8/23

• The positions of 4 behavioral segments have been reconsidered and revised according to Takahiko INOUE and Yukinobu OKAMURA (2010）Explanatory notes of 1:200,000 marine geological map around the northern part of Noto Peninsula．Seamless geoinformation of coastal zone, "Northern coastal zone of Noto Peninsula", Numerical Geological Map S-1, Geological Survey of Japan. Parameters have been changed accordingly. The names of 3 of these behavioral segments have been changed along with the revisions.
  Northern Coastal Area of the Noto Peninsula:329-01 Monzen-oki　329-02 Saruyama-oki(former name Wajima-oki)　329-03 Wajima-oki (former name Machino-oki)　329-04 Suzu-oki (former name Noroshi-oki)
