What's New
2024/12/20
We have added about 400 locality data. (About 200 newly added data and 200 updated data.)
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．Marine Geological Map, "Northern Noto Peninsula Costal Area", 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)

Outline

This website contains information of active faults in Japan, sorted by the concept of "behavioral segments" [McCalpin, 1996]. Each fault is subdivided into behavioral segments based on surface trace geometry and rupture history revealed by paleoseismic studies. Faults shown on the index map are linked to a database of behavioral segments, which contains information of geologic and paleoseismic parameters including slip rate, slip per event, recurrence interval, and calculated rupture probability in the future. Behavioral segments can be searched also by name or combination of fault parameters. All those data are compiled from journal articles, theses, and other documents. We are currently developing a revised edition which is based on an improved database system.
