Research on Urban Earthquake Emergency Management System

Abstract eng:
It has been demonstrated repeatedly that a timely macro-understanding of seismic disaster scenarios and effective emergency management always play the key roles in aftershock rescue and disaster mitigation. In our research, Urban Earthquake Emergency Management System (UEEMS), as a comprehensive data integration and analysis system for seismic emergency management, is developed on ArcView9.0 and Oracle 9i. UEEMS is mainly composed of four subsystems: central control system (CCS), earthquake situation analysis system (ESAS), earthquake emergency response system (EERS) and earthquake emergency command system (EECS). The purpose of this paper is to introduce the structure and functions of four subsystems, and the establishment of system database of UEEMS. CCS is in charge of all sorts of information transmission among other subsystems. By means of interface design, the mechanism of processing and analyzing earthquake precursor and observation data is embedded in ESAS to predict the parameters of forthcoming earthquake. According to these parameters, the estimation of seismic emergency levels can be more rapidly made in EERS based on the earthquake influence field and the spatial variations of seismic intensities. Furthermore, using spatial analysis of GIS and embedded disaster assessment models, EERS can illuminate the spatial variations of seismic catastrophe. Finally in EECS all estimated data about earthquake disaster affection will be continuously modified in light of real-time feedback on earthquake stricken areas. Meanwhile the demands of rescue materials and the countermeasures about emergency command and will be offered to decision makers.
