上海市地震局综合深井台地磁记录数据质量初步分析

摘要

Comprehensive observation of deep well in Earthquake Administration of Shanghai Municipality is carried out in recent years in order to reduce the influence caused by city rapid development .In order to determine the reliability and accuracy of the data of geomagnetic observation in deep wells ,geomagnetic record data of the ground stations are selected and compared .The results show that the diurnal variation morphology and ranges of the two forms are consistent .It is indicated that the geomagnetic observa‐tion in deep well is feasible .%城市的快速发展使地震前兆监测环境日益恶化，特别是地磁记录观测受到严重影响。为减少人为干扰对地磁记录的影响，近几年上海市地震局开展深井综合观测，其中就包含地磁记录。本文就地面台站的地磁记录资料和深井地磁记录的资料进行对比，分析其记录数据的特征，给以后开展深井地磁观测记录的单位提供参考与借鉴。
