ABSTRACT
Geological Survey of Japan(GSJ) proposed to compile a small-scale natural hazards map especially focusing on the geologic hazards at the 29th International Geological Congress(IGC) in 1992. GSJ organized commmittees and held workshops, symposium and meeting among the persons concerned to promote this project since 1993. We discussed and agreed that we should firstly deal with geologic hazards such as seismic hazard, volcanic hazard, landslide, coastal erosion/deposition, karst collapse, land subsidence and seawater intrusion in the eastern Asia. We also agreed to publish 1:5,000,000 scale hazards map showing not only past events of these hazards on the geologic and topographical background data but also those potential of occurrence in near future, and to degitize those data with relevant database. This project was endorsed as one of the International Demonstration Programs by International Decade of Natural Hazards Reduction (IDNDR) and a program of Global Natural Hazards Map by Commission for the Geological Map of the World(CGMW).
