2014年景谷地震震中附近地裂缝成因初析
|
摘要
2014年10月7日云南省景谷县发生了M_s6.6级地震,震中附近出现了一系列的地裂缝。本文通过对这些地裂缝的实地调查,结合震源机制、余震分布、烈度分布等其它信息,综合分析探讨了这些地裂缝的成因。结果显示,这些地裂缝都是斜坡在地震的震动影响下,由于重力作用而形成的。在此基础上,本文还深入讨论了不同裂缝的形成机制和模型,为以后甄别地裂缝成因提供了良好的范例。
The Jinggu earthquake(M_s6.6) occurred on October 7~(th).2014 in Yunnan province,led to severe ground fissures near epicenter region.Base on field survey.combining with focal mechanism,aftershock distribution and isoseismal maps,we analyze the possible cause of these ground fissures,and find that the action of gravity plays an important role in the fissure formation.We also discuss the different mechanisms and models of these ground fissures,which could provide a good example for research of ground fissures in future.
