description The invention discloses a moving target emergency tracking system and method and a seismic hazard range determining system and method. The moving target emergency tracking system comprises a server and a mobile terminal, and a moving target database is established at the server; when an emergency tracking event occurs, the server screens out a tracking target and sends an emergency tracking request to the mobile terminal carried by the tracking target; the mobile terminal receives and analyzes the request and sends current position information to the server so that emergency tracking can be started. The seismic hazard range determining method comprises the following steps that firstly, a rough disaster area range is determined according to the epicenter and intensity, a moving target permanently staying in the rough disaster area range is screened out, emergency tracking is conducted on the moving target, the feedback position of the moving target is obtained, the rough disaster area range is divided into a plurality of sector units with the epicenter as the center, and points, closest to the epicenter, of all the units are connected in sequence so that a more accurate severely-damaged area of a disaster area can be obtained. The moving target emergency tracking system and method and the seismic hazard range determining system and method can reduce the network transmission data volume, reduce the storage pressure on the database of the server and improve the determining efficiency of the severely-damaged seismic hazard area.
