Although the design determines the post-earthquake trend of an earthquake based on historical earthquake data, it still has the following defects: In this design, less earthquake-related information is collected. When judging the post-earthquake trend based on the less earthquake-related information, it will lead to inaccurate judgment of the post-earthquake trend.

At the same time, the domestic main server and the domestic backup server perform dual-machine hot standby and status monitoring in the private network through Keepalived, and provide services to the outside in the form of a virtual IP. Users only need to access the virtual IP to use this method. When accessing the virtual IP, it will first point to the domestic main server.
