有关汶川8级地震的二次现场考察
|
摘要
2008年5月12日14时28分汶川发生8级地震,造成通讯中断,为了及时了解紫坪铺水库大坝受损情况,发震后不到半小时就出发,距发生8级地震后不到3小时到达水库大坝,用相机记录下大坝受损情况,向大坝上的相关领导和业主汇报8级地震情况及其与紫坪铺水库大坝的位置关系,当天返回省地震局后立即向相关领导和部门汇报。2008年2月14日21时36分都江堰市发生3.3级地震,2月15日组织去现场工作,现场调查认为,地震中心点董家山隧道口的烈度为Ⅳ度;发震构造为龙门山前山断裂。
In order to know the safety situation of the Zhipingpu Dam after the 2008 M8.0 Wenchuan Earthquake,we overcome many difficulties to get there immediately within three hours after the earthquake and took damaged pictures of the dam.Then we drew a map shown the relationship between earthquake and the dam sent the pictures and the map to the owner and leaders for responsibility of the dam.Before the 2008 M8.0 Wenchuan Earthquake,there was an M3.3 earthquake on 14 February 2008.After that day we got there to investigate.The epicenter is near the Dongjiashan Channel and its intensity is about Ⅳdegree.The seismogenic fault is the front mountain faults that belong to the middle part of Longmenshan faults.
