简介:在1954年2月11日,有Ms7.3的地震发生在Hexi走廊的Shandan县,韦斯特中国。它是在在1949以后的西北中国的第一大地震。地震留给了47个人死者,伤害的332个人和几万个人无家可归者;将近7277座大楼被损坏或崩溃并且性质损失在不平的估计是超过10亿Ynan(RMB)。在meizoseismai区域,紧张是,Hongsihu盆和Shandan县是最严重的损坏,并且在Shandan,地震受灾的区域是4800km2。在纸,简短介绍被介绍给Shandan地震,包括基本参数,地震紧张的分发和自然环境。造破坏的特征特别地被讨论,地震灾难分发analysed.Finally展示,经济损失评估也是,象对地震和灾难减小的保护的含意一样的地震损坏,经验和课同样多的原因被总结。
