云南宾川地震信号发射台的流动观测数据服务系统及数据质量评估
Data Service System and Data Quality Sssessment for Mobile Observation of Transmitting Seismic Stations in Binchuan,Yunnan
【摘要】 对2011年以来云南宾川地震信号发射台的实验数据进行规范化处理,整理原始Reftek数据库,构建为统一的G1数据库(Mini SEED格式),并提供SAC等数据格式的截取服务。对台站分布及数据连续性、各台站仪器类型及经纬度位置变更情况、气枪激发时刻与集中加密实验、台站背景噪声水平等进行数据质量评估,并对宾川附近天然地震分布进行了统计分析。结果表明:G1数据库是对历史数据的检验,格式与信息均可达到统一,也可作为新疆、甘肃等地主动源数据整理的模板。
【Abstract】 We made standardized processing of the Reftek database of the transmitting seismic stations located in Binchuan from 2011, eventually we got the G1 database( Mini SEED format) and provided data interception service with the format of SAC,etc. We made data quality assessment such as the station distribution and data continuity,equipment type and position changed information, triggering time and concentrated experiments,and the ambient noise level. We also made statistical analysis of earthquake distribution. The results indicate that the G1 database is the test of historical data with uniform format and information,which can lay the foundation of further study and be the template of active source in Xinjiang,Gansu and other places.
