大庆地震台网近震震级偏差分析与校正

Analysis and adjustment of regional seismology magnitude deviation in Daqing Seismic Network

选取大庆地震台网2002—2009年近震报告资料,以《黑龙江省地震目录》给出的震级为标准,进行震级偏差统计。按地区分段校正后,震级精度明显提高。

This research selection regional seismology material in Daqing Seismic Network from 2002 to 2009. Taking the magnitude which provides by 《Seismic Catalog of Heilongjiang Province》 as a standard, the magnitude deviation statistics is carried on. After dividing the area and delimits the partition adjustment, the magnitude precision enhances obviously.
