Construction of Telemetric the Digital Seismic Observatory System of Datong of Shanxi Province

The structure, seismic monitoring capacity, functions and technical features of network as well as the technical system of station, power supply system, central control system, lightning proof system, relay station and communication channel are introduced. The data from the Telemetric the Digital Seismic Observatory System of Datong of Shanxi Province in the test period are analysed. The results show that the seismic monitoring capacity, dynamic range, and earthquake locating speed of the Telemetric the Digital Seismic Observatory System of Datong of Shanxi Province are superior to the analog seismic network. The minimum earthquakes that can be detected in the most region within the network and around its eastern edge is [WT6BX]M[WT6BZ]=1 5. The time needed for the earthquake location is usually less than 10 minutes. The completion of this network will provide more useful digital seismic data for seismological study and earthquake prediction.
