摘要

山西省晋中地区东南,地震活动频繁,特别是沿晋获断裂带分布的几个小型断陷盆地,相继发生了多次震群活动。晋获断裂是太行山隆起区上的一条主要活动断裂,地震活动频繁,具有一定不均匀性,这种差异可能反映了断裂带不同区段的新构造活动的差异,它与近东西向太原——石家庄横向构造带相交。这里对沿晋获断裂带上分布的几个断陷盆地的震群活动做一个初步探讨。
In the Southeast of Jinzhong area,Shanxi Province,the seismic activity is frequent;especially several small graben basins along the Jinhuo fault zone,where the earthquake swarms have become active several times.The Jinhuo fault is a major activity fault in Mt.Taihang up warping zone.The seismic activity in this area is frequent and nonuniform.This difference probably reflects the difference of new structure activities between different sectors of the fault zone.It intersects the Taiyuan-Shijiazhuang crosswise structure belt.In this article,a preliminary discussion is held on the earthquake swarms activity of several graben basins distributed along the Jinhuo fault zone
