Abstract: In Shisanling seismic station, a Monitoring and Management System for Earthquake precursory Data is constructed to integrate all the earthquake monitoring means installed in this station on one platform, including seismometer, GPS receiver, geoelectricity, etc. In this paper, we briefly introduce the structure and function of this system. And we describe in detail the function of the Monitoring and Management software of Earthquake Precursory Data, whose name is DataMonitor. This software can monitor the waveform of precursory observation data, detect data quality problems, make data statistics at field, table and database level, and process data using various methods. With this system, collecting, loading into database, managing, processing, and monitoring of all those measuring means mentioned above can be conducted in one single platform, this reducing significantly the daily routine work of station operators and system maintenance needed.

Key words: Precursory Observation Data, Monitoring and Management, Central Monitoring, Shisanling Seismic Station
