Following high demand on detailed information for active faults in Japan after the 1995 Hyogoken-namnbu earthquake, we compiled completely new active faults map of Japan with a scale of 1 : 25,000 based on precise interpretation of aerial photographs.We assembled active faults about 140 groups based on the following criteria ; 1.faults more than 10km long in dimension, 2. Isolated from the neighboring faults at least 5km apart, and similar type of faulting, strike and sense of faulting. We also digitized location of active fault traces and their parameters such as displacement, fault reference etc. to GIS data set.We prepared maps for type, activity, and density of faulting to known the regional characteristic of active faulting in Japan. We also examined the possibility of occurrence of new active faults and expansion of faults based on the mode of cumulative slip distribution along their traces.This digital fault map differs much in accuracy from "Active fault in Japan : Sheet map (1 : 200,000) and inventories" and may provide with useful information to geoscientists and engineers for their purposes.

1995年兵库县南延地震后，人们对日本活断层的详细信息提出了更高的要求，我们根据航空照片的精确解译，编制了全新的1：25,000比例尺的日本活断层图。与相邻断层相隔至少5 km，且断层类型、走向和方向相似。将活动断层的位置及其位移、断层基准等参数数字化到GIS数据集上，制作了断层类型、活动性、密度图，了解日本活动断层的区域特征。此外，还根据断层的累积滑动分布模式，对新的活动断层的产生和断层扩展的可能性进行了研究。该数字断层图与“日本活动断层：单张图（1：20万）和目录”的精度有很大的不同，可为地球科学家和工程师提供有用的信息。
