Abstract

We constructed a database of land use, land use control, and disaster risks in 500-meter grids throughout Japan. These risks included earthquakes, floods and landslides. Then, we calculated population exposure in 2010 and 1975 as an indicator of disaster risks, and analyzed the relationships between population exposure and land use with land use control. Earthquakes risk and floods risk increased, while landslides risk decreased between 1975 and 2010. Excluding in Tokyo, Nagoya, Osaka, the overall disaster risk in the areas that changed from farmland to urban environments between 1975 to 2010, is higher than in the areas that remains urban environments. Moreover, the overall disaster risk in areas where urbanization is limited is higher than in areas designated for urbanization.
