In order to enhance the timeliness of the release of earthquake thematic maps and to improve the service capability, in this paper we design a set of automatic generation and push system for earthquake thematic maps based on the MQTT protocol. The system maintains a long connection with the earthquake quick report system through the mobile Internet, uses the MQTT protocol to receive the earthquake quick report information in real time, generates the earthquake influence field according to the seismic intensity attenuation model, and then uses the ArcPy site package to perform related spatial analysis and automatic map output. Finally by using the development interface of enterprise WeChat, the rapid release of earthquake thematic maps was realized. The automatic earthquake thematic map generation and push system has provided services to relevant personnel of the Earthquake Administration of Fujian Province and the earthquake administrations of various cities, and has achieved good results in dealing with several earthquakes in Taiwan.
