Eastern Asia Geological Hazards Map : Paper and Digital Versions

The Eastern Asia Geological Hazards Map(paper version) and Interactive Geological Hazard Map of East and Southeast Asia with GeoHazardView(digital version) respectively were published in 2002 and 2003 by the Geological Survey of Japan (GSJ), AIST. These constitute the first attempts to compile small -scale hazard mapping focused on the geological hazards in eastern Asia. The paper version consists of a geological hazards map of endodynamic origin that includes seismic hazards in particular tsunami and volcanic ones; one sheet of hazards of exodynamic origin partly induced by human activities such as landslides, coastal erosion, and deposition; one sheet explaining the legends, and an explanatory pamphlet. Because of paper version limitations, a digital CDROM version was produced to make hazard information readily available both to geologists and the general public. In order to mitigate geological hazards, the general public also needs to be well informed about the problems. The CD-ROM presents all the collected geological hazard information in the mapping project in an interactive way by the use of newly developed GeoHazardView software. The user can access, view, manage, update and enlarge or reduce the scale on the screen at will. To handle both types of maps easily and for better user understanding, the geological hazards are summarized.
