【摘要】 利用云南区域台网1966年至2006年的地震目录,系统研究了云南"三江"(怒江,澜沧江,金沙江)流域内的地震活动性,给出了该区域、以及以各河流形成的3个次区域的地震活动时空分布特点和b值结果,并进行了讨论,根据研究结果,认为拟建、在建的水电工程可能造成水库诱发地震是一个值得高度重视的问题。更多还原

【Abstract】 Based on the catalogues from 1966 to 2006 recorded by Yunnan Regional Net-work,the seismicity in Yunnan "Three Rivers"(Nu River,Lancang River,Jinsha River) is studied.The characteristics of the temporal and special distribution of seismicity,b value,in the region,and the three subregions of each River are analyzed and discussed,The result shows that the possibly induced reservoir earthquake for the hydropower project is a security problem of engineering earthquake worthy of high recognition.更多还原
