The study area is well known for its landslide vulnerability, and lies on the active fault zone that divides the Japanese Island. Study was carried out at Yamakoshi Village, an intermountain agricultural region that is situated above the fault plane. Field surveys, interpretation of high-resolution aerial photos and analysis of local topography using high-resolution DEM data were performed for the study area. Following results were obtained by investigating the relationship between local topography and agricultural landuse practices, and earthquake led damages on agricultural fields. Damaged area is a hilly mountainous area where complex formation of small ridges and valleys are present. In such places, harnessing local topography, a traditional complex farming: arrangements of paddy terrace and carp-breeding ponds alternately or block-wise, have been adopted. Sediment disasters led by the earthquake are predominant in the area. Damages are more severe and significant at paddy terraces and carp-breeding ponds that were constructed at depression (concavity) of the valleys. The damages are further escalated by snow and snow run off that presumably occurred during the following winter after the MNPE. In the context of local topography of the study area, agricultural lands with favorable soil and water conditions tend to have high potentiality for earthquake sufferings. Developments on agricultural landuse planning that help in bringing disaster prevention are required.
