In r...Once an earthquake occurs, the rapid and reliable evaluation of earthquake damages will be of great importance to the mitigation of earthquake hazards and the reconstruction of the disaster area. In recent years, a lot of work has been done in the development of GIS-based systems for improving and accelerating the evaluation of earthquake damage, but such systems were mostly developed for the urban region in developed countries. Therefore, we developed an “Earthquake Damage Evaluation and Damage Data Management System (EDMS)” for the rural regions in the southwestern China on the guidance of the “Working Regulation and Technical Guideline for Earthquake Field Investigation” issued by China Earthquake Administration in 1998. This system provides elementarily visualized tools for evaluating earthquake damage and managing damage data. The mapping and interpolation functions of GIS developed in the EDMS system have also facilitated the analyses of earthquake damage and seismic intensity as they are more accurate than the previous ones. The analysis of Lijiang earthquake of 1996 by using this system has revealed that the seismic intensity of this event does not decrease simply with the increase of distance to the epicenter, but displays a complex distribution pattern. This complexity can be attributed to the thick alluvium in the basins and the structure of fault systems in the region. Although it is an incomplete system just suitable for rural regions in southwestern China, the EDMS system is expected to be applicable to the evaluation of earthquake damage in broad rural regions of China, and it may be helpful to raising the ability of earthquake damage mitigation in China.Read More
