At present, we assessed eruptive risk in the region of Kyusyu and Hokkaido, Japan on a trial basis. We have used a digital model of the topography, the simple methods for eruptive risk assessment and some assumptions of the way in which the eruption disasters in forthcoming decades will develop to create a map of the eruptive hazards from all active volcanoes in whole Japan. Mapping on the basis of many geological informations, paper of natural hazards and some assumptions: 1) subject of study hazard: vent area, tcphra fall, ballistics, lava flow, pyroclastic flow, surge, gases and others 2) target for the geological and historical eruption data: last 1000years (geological target is 30k_age) 3) Topographic model: 1km mesh (except for vent area) If it refuses, this report has not sugges some idea to forecast volcanic activity and urgency of eruptive disaster.
