In order to further study the seismic characteristics and reduce the earthquake caused by the most scientific method, this paper designs and realizes the GISbased seismic positioning and waveform display system, the system is based on the QGIS secondary compilation and development as a GIS display module, equipped with MySQL database storage of seismic data and various types of information data. The seismic information can be visualized directly to the researchers, which is convenient for further analysis and research on the earthquake that has occurred, and provides the basic research value for the earthquake disaster prevention and early warning work.
