利用太原盆地地震活动判断华北地震区地震活动趋势

Determining the Seismicity Trend in North China Seismic Region by the Seismicity in Taiyuan Basin

通过对１９７０年以来太原盆地及其两侧山区ＭＬ≥３．０地震的研究，发现在太原盆地北部、沿交城断裂、太谷断裂以及盆地两侧的４个隆起部位发生的ＭＬ≥３．０地震与华北地震区距太原盆地６００ｋｍ范围内发生的ＭＳ≥５．

Through an analysis for the M ≥3 0 earthquakes in Taiyuan basin and its bilateral mountainous region since 1970,the some relations between the M ≥3 0 earthquakes that occurred along Jiaocheng fault and Taigu fault in Taiyuan basin and in its bilateral mountainous region and the M S≥5 8 earthquakes that occurred within 600 km distance from Taiyuan basin have been discovered.
