“国家数字测震台网数据备份中心”技术系统建设及其对汶川大地震研究的数据支撑
|
摘要
"十五"期间中国地震观测系统得到了迅速的发展,中国地震局地球物理研究所于2007年底完成"中国数字地震观测网络"项目"国家数字测震台网数据备份中心"技术系统的建设.该数据备份中心可以准实时地接收并存储全国1000多个固定地震台站的信号,具备海量数据校验、数据格式转换、以用户定制方式截取地震事件波形数据和数据网络下载的功能.到目前为止,已累计为国内10多个科研单位开展的70多项研究提供了近70TB海量波形数据的服务,特别在快速开展的汶川特大地震震后相关研究中提供了重要的数据支撑和保障作用.本文介绍了"国家数字测震台网数据备份中心"技术系统建设、汶川特大地震数据服务快速响应、大地震快速响应波形数据自动截取系统建设,以及对地震学及相关科学研究的数据支持情况.
The seismological observation system in China has experienced rapid development over the Tenth Five-year Plan period.The technical system construction of Data Backup Centre for China Seismograph Network is one of the most important parts of China Digital Seismological Observation Network program,which has been completed in Institute of Geophysics,China Earthquake Administration at the end of 2007.The data centre is capable of receiving near realtime continuous waveform data from more than 1000 permanent seismic stations,and also manipulating that data,including data quality control,data format converting,event data extraction by user order and data download service via internet.By now,we have supplied about 70 TB waveform data to over 70 researches of over 10 academic institutes and universities, especially the studies concerned with the Wenchuan great earthquake.The paper will give a brief introduction to the technical system construction,rapid response of data service to the Wenchuan earthquake studies,construction of automatic event-extracted system for rapid response of large earthquake in near real-time and data support to scientific researches.
