Ideas of establishing the information system for emergence decisions on the protection against earthquakes and disaster reduction in cities (application of GIS)

Abstract

With urban reformation and opening becoming deeper, the work of protection against earthquake and disaster reduction would be more important. In this paper, some ideas are suggested about establishing the information system for emergency decisions on protection against earthquake and disaster reduction in cities. The information system mainly includes a subsystem for rapid evaluation of damage loss from earthquake (which inclu&-, input of seismic information, distribution of earthquake intensity, ecaiuation of seismic fragility on all social factors and etc.) and a subsystem for the decisive information of seismic emergency (which mainly includes project of disaster relief, project of personnel evacuation, dangerous degree warning for the dangerous articles-storing places and protection measures against them, assistant decision on fire due to earthquake, location of head-quarter for providing disaster relief, and etc.). It is thought that the data investigation and collection about all kinds of buildings (including lifeline engineering) are the most important and difficult work as establishing this system.
