Seismological Data Sharing
|
Seismological data sharing is one of the pilot projects concerning scientific data sharing initiated by the Ministry of Science and Technology of the People’s Republic of China (MSTPRC) in 2003. In accordance with the unitary plan and management of China National Facilities and Information Infrastructure for Science and Technology Program, the project was headed by CENC and participated by the institutions directly under CEA and 31 provincial earthquake administrations. Initiated as a society-oriented, networking and intelligent system for management and service of seismological data sharing, the project has facilitated standardization of seismic data acquisition, processing and storage. After 4 years of work, a series of measures for administration, grading and classification standards and quality testing criteria concerning seismic data service have been formulated and a persistent, stable and dependable operation mechanism for seismic data service has been established. The seismic data accumulated over a long period of time in China have been standardized by integration and transformation and a standardized database cluster has been set up. For example, standardization of the seismic waveform data and phase data collected since 2001 by the national, Capital-circle and 31 regional digital seismograph networks has been accomplished and a database system has been established, with on-line data exceeding 1000 GB. For data management and service, a seismological data sharing system has been set up, which boasts advanced technology, complete function and need gratification for various users. Users have access to the earthquake data service via China Earthquake Data Center website: http://data.earthquake.cn, which was launched on Sept. 28, 2006. Chen Jian-min, Director General of CEA and Cheng Jin-pei, Vice Minister of MSTPRC attended the ceremony. The data sharing service will greatly improve availability of the seismic data. After an annual acceptance inspection of the project, a MSTPRC specialist group reached the conclusion that the seismological data sharing project is a great success and is expected to have a wide application; they also deemed that the project has demonstration effect for promoting national scientific data sharing service.
