广东“十五”测震台仪器方位角普查校正工作

Verification of the Seismometer's Azimuth of Guangdong Seismic Stations in the “10th Five-Year Plan”

广东省地震监测中心于2012年08月至12月开展"十五"测震仪方位角普查校正工作,一共普查了43个地面测震台,于2013年9月通过验收。仪器方位角普查结果可供数据应用研究机构和科研人员参考和使用,特别是对仪器水平向方位角准确性要求比较高的,可根据偏差结果、仪器校正时间和地震计型号,对校正前的历史数据,进行反方向旋转相同角度的数据处理校正。

Guangdong Province Earthquake Monitoring Center carry out azimuth survey and correction for the＂10 th Five-Year Plan＂ seismometer from August 2012 to December, and a total number of 43 ground seismic stations pass the acceptance in September 2013. This work was summarized as follows： the research institutions and researchers can reference and use the seismometer＇s azimuth survey data, especially of the high level accuracy of the seismometer＇s azimuth. Based on the results, the deviation calibration time and seismometer model, the historical data before correction can be processed with rotating the same angle in the opposite direction.
