GIS-based seismic hazard prediction system for urban earthquake disaster prevention planning

A basic framework of a GIS-based seismic hazard prediction system for urban earthquake disaster prevention planning is developed in this study, incorporating structural vulnerability analysis, program development, and GIS. The system is integrated with proven building vulnerability analysis models, data search function, spatial analysis function, and plotting function, realizing the batching and automation of seismic hazard prediction and the interactive visualization of predicted results. The system is applied to a test area and the results are compared with results from previous studies to verify that the system can provide data support and aid decisionmaking for the establishment and implementation of urban earthquake disaster prevention planning. Results from this study are essentially the same as the results of 2003 and slightly better than the results of 1993, which highlights the reliability of the fragility analysis method applied in this system.
