Introduction
Asian countries have been severely damaged not only for human lives but also industrial infractures because of frequent occurrences of many kinds of natural disasters, high population density and insufficient policy to prevent disasters.
In order to mitigate those damages, it is necessary to investigate natural disasters in the past time, to make an assessment of such hazards and to announce them to concerned people widely. For this purpose, it is useful to compile hazard maps and to develop the relevant database.
This project aiming to compile small-scaled (1,5,000,000) hazard maps was proposed by Geological Survey of Japan (GSJ) to related institutes including Eastern Asia and international organizations in 1992. GSJ was preparing the project through the International Forum " Hazard Mapping" held at Tsukuba in 1993 in co-operation with concerned organizations. Some committees/working groups were organized and the project starated from 1994. During the IDNDR Yokohoma World Conference in March 1994, informal meeting of the project was held and reported their progress. As the first target, we focus on geological hazards shuch as earthquakes, volcanic eruptions, landslides, coastal erosion and so on in Eastern Asia.
Objectives
1. To develop databases and Geographic Information Systems (GIS) on natural hazards (mainly geological hazards) of Eastern Asia.
these maps consisted of not only catalogue of those historical records but also more detailed documents describing characteristics and damages, index of geosience maps, directory of scientists and organizations etc. In a given area, which are available to concerned people using PC.
2. To compile factor maps of Eastern Asia
these maps aim to show background informations for interpretation of geologic hazards such as topography, geology, etc, in a given area.
3. To compile disaster distribution maps of Eastern Asia
these maps show the distribution and characteristics of each geologic disasters such as earthquakes, volcanic eruptions, landslide, etc.
4. To compile geologic hazards map of Eastern Asia
these map is one of the final outputs of the project. Main geological hazards factors and risks/possible damage should be described. All data are digitized and is renewed every year.
