摘要
2016年12月18日11时08分,山西省太原市清徐县发生4.3级地震,虽然有感范围涉及6个地市,但由于震源深度较大,房屋建筑质量相对较好,抗震性能较强,因此此次地震未造成房屋破坏和人员伤亡。通过分析这次地震的烈度图长短轴特征、通过震源机制解研究此次地震的主破裂方向,破裂特征,同时结合震中位置附近的活动断裂倾向、走向、错动性质,综合分析认为发震断裂是田庄断裂。
A M4.3 earthquake occurred at 11:08 on December 18, 2016. A range of feelings the people in 6 cities felt the shaking. The earthquake caused no damage and casualties because of the deeper focal depth and the better housing quality. The main fracture direction of the earthquake is studied by focal mechanism solution. At the same time, the tendency, strike and dislocation of active faults near epicentral location are also analyzed. It is considered that Tian-zhuang fault is the seismogenic fault.
