Based on the analysis of the information needs in different stages of earthquake emergency,we apply the visual information graph expression to carry out the integration and aggregation of seismic data,to construct the visualization product for after earthquake information service,and to develop a rapid visualization output system of earthquake emergency information(RVOS). The system is a visual interactive service platform of seismic information,which realizes the visual publishing task of H5 pages on desktop and mobile terminals. It provides a basic platform and innovative ideas for further expanding and enriching the visualization of earthquake emergency information in the future.
