摘要
文章采用大连地震台1983年到1986年四年间所记录的面波震级Ms≥4.0级的地震一千余例与《中国地震台临时报告》中所给定的面波震级进行比较,算出大连地震台的台基校正值,以及不同震中距,不同震中方位,不同震级的震级偏差及其校正值.
Making a comparison between two surface wave magnitudes which are given by Dalian station and Preliminary Seismological Report of Chinese Stations, respectively, station correction of Dalian is computed by means of data containing more than one thousand earthquakes (Ms≥4.0) during four years from 1983 to 1986. Magnitude deviation and correction value with different epicenter distance, azimuth and magnitude are also given in this paper.
