共和 7.0级地震的发生及共和盆地内古地震遗迹的发现 ,说明共和盆地不属于低烈度区 ,其地震危险性是不容忽视的 .在诸多学者研究的基础上 ,分析了共和地震的构造背景 ,讨论了共和地震的孕震过程 .发现该次地震的孕育经历了近 2 0年 ,并且可以分为长、中、短、临 4个阶段 ,反映了地壳介质由弹性形变、朔性形变、硬化直至破裂的过程
The occurrence of the M 7.0 M Earthquake and the discovery of ancient earthquakes in the Republican Basin indicate that the Gonghe Basin is not in the low intensity region and its seismic risk can not be ignored.On the basis of many scholars’ studies, the tectonic background of the Gonghe Earthquake is analyzed, The seismogenic process of the Republican earthquake was discussed, and it was found that the earthquake had experienced nearly 20 years and could be divided into four stages: long, medium, short and temporary, reflecting that the crustal medium is composed of elastic deformation, Until the rupture process
