The earthquake emergency response information service platform of China Earthquake Administration Emergency Command Center is a national platform for convergence and sharing of various earthquake emergency products. The platform provides the whole chain of earthquake emergency response vocational information for all level commanders and supports information for emergency decision-making. The platform has functions of seismic emergency service response level service,product convergence,on-site disaster convergence and emergency response work information support. Platform users involve all units under the CEA,and the information services cover the earthquake commanding,earthquake rapid report,seismicity analysis,disaster flash report and on-site emergency. The platform realizes the connection of operational management and vocational work through user grouping and task division,gives full play to the advantages of the units in the whole seismological system,and realizes emergency coordination and operational linkage among the units. The platform has been applied in several destructive earthquake emergency cases in rapidly completing the convergence and sharing of information,providing powerful information support for the development of emergency disposal work. To enhance the service effect,the platform will be further improved and enhanced in terms of refining the granularity of information services and convergence,auto-docking of emergency products and strengthening of information support in the future.
