Abstract
With the implementation of national seismic intensity rapid reporting and early warning, China will build a nationwide earthquake intensity reporting and early warning network by 2022.The push of earthquake warning information services for the government, the public and various industries, and it is an effective means to mitigate earthquake disasters. This paper develops and builds an end-to-end platform for earthquake early warning information service based on the MQTT protocol, so as to realize the whole process of information push, processing, subscription and warning output. The time-delay test results show that the platform push delay is less than 1s under internet conditions.
