A STUDY ON THE EFFECT OF LAND USE CONTROL BY ACTIVE FAULT ZONING IN JAPAN
Japan entered an expected longstanding depopulation process in 2006. In this situation, it is important to avoid disaster social impacts due to the disaster by guiding population from vulnerable area to safer areas. This research focused on the risk of active faults among various kinds of natural hazards and studied on the effect of the land-use control along active faults in Japan. First, the meaning of land-use control by active fault zoning in the society whose population started to decrease was discussed. Japan has not adopted earthquake fault zoning act due to several reasons. However, considering the current depopulation process, introduction of the fault zoning act becomes meaningful. Then, the distribution of population and buildings in the neighborhood of active faults was analyzed based on GIS databases of active faults, population and building stocks. The effect of land-use control using fault zones was discussed based on the obtained results. If a fault zone with 0.4km width was decided, referring to the fault zoning act in U.S., it was estimated that the population living inside the fault zone was 2.3% of the total population in Japan. The effect of land-use control was different according to the region. The population living inside the fault zone increased in proportion to the width of the zone.
