日本の活断層の縮尺1/25,000での新規判読・図化と地理情報データベース化

特に技術的側面を中心とした報告

抄録

Following high demand on detailed information for active faults in Japan after the 1995 Hyogokennambu earthquake, we compiled completely new active faults map of Japan with a scale of 1: 25,000 based on precise airphoto interpretation. We also digitized location of active fault traces and their parameters such as displacement, fault reference etc. to GIS data set. This digital fault map differs much in accuracy from“Active fault in Japan: Sheet map (1: 200,000) and inventories”and may provide useful information to geoscientists and engineers for their purposes.
