  • 简介:Mansehra的地点地震地位于活跃政体,在NW喜马拉雅山脉作为水晶的越过水坝落下的水地区和Hazara克什米尔Syntaxis知道,巴基斯坦。为这个地点的地震危险评价(SHA)被认为地震是来源地区,适当变细方程的选择,近的差错效果和最大的潜在的大小评价执行了。Mansehra戳,Oghi差错,Banna戳,Balakot砍地区,主要边界戳,Panjal戳,Jhelum差错和Muzaffarabad差错并且,推进到南方,Sanghargali,Nathiagali,和Thandiani戳是在Mansehra的50km半径以内的最批评的构造特征。用从1904~2007的可得到的仪器的地震学上的数据,SHA被执行了。在区域的另外的重新激活的批评构造特征被调查了。与到Poonch的从Balakot的120km的差错长度,在他们之中,Balakot-Bagh差错根据地质/结构/地震学上的数据被看作了最批评的构造特征。7.8用四种回归关系被分到Balakot-Bagh差错的最大的大小的潜在的地震。0.25g(为50年的exceedance的10%概率)和0.5g的山峰地面加速价值用概率、确定的途径在变细方程的帮助下被计算了。
