摘要
对大丰地震台井下摆1983-1992年的观测资料统计分析,发现井下摆测定的震级普遍低于江苏省地震局台网的平均震级,且和震中距有一定的关系。通过对震级偏差的计算得出大丰台的台站校正值。同时,对偏差的原因进行了探讨。
In this paper seismological observation data of Dafeng borehole seismograph during 1983-1992 have been analysed statistically.Generally the magnitude determined by Dafeng borehole seismogrph is lower than average magnitude determined by Jiangsu seismological observation network.Furthemore the deviation is related to epicentre distance.Finally station eorrection value was obtained.The cause of magnitude deviation of borehole seismograph has been studied.
