| 摘 要： | 利用云南及周边地区中强地震震源机制解资料,采用对震源机制参数进行统计的方法,详细分析了地震断层类型和云南地区的现代构造应力场特征.结果表明,云南地区发生的中强地震走滑型地震占绝大多数,比例为80%,正断型和正走滑型与逆断型和逆走滑型地震所占的比例相当,分别约为8%.云南地区应力场接近水平,地震错动面的倾角较陡.云南地区...

| Abstract: | In this paper,using focal mechanism solutions of moderate-strong earthquakes in Yunnan and its adjacent areas,and based on the statistical analysis of the parameters of focal mechanism solutions,we discussed in detail the earthquake fault types and the characteristics of modern tectonic stress field in Yunnan region.The results show that most moderate-strong earthquakes occurring in Yunnan region are of the strike-slip type,amounting to 80%of the total.Normal faulting and normal with strike-slip and reverse... |
