Abstract:
|
The MS810 Wenchuan earthquake on May 12 , 2008 caused heavy casualties and economic loss.According to the f ield investigations , the characteristics can be described as follows : The meizoseismal region with an intensity of XI shows an obviously zonal distribution and suffered serious destruction from the earthquake , and the destruction perpendicular to the earthquake surface rupture decreased sharply. At the same time , the intensity X and IX regions perpendicular to the rupture are narrow and therefore their coverage area is small . The intensity on both sides of the rupture attenuates rapidly , but intensity VII and the VI regions are wide , the latter covering about 240 , 000 km21 In intensity VI region , the damage area
perpendicular to the rupture in the southern part is much larger than that of the northern part. Also , much new understanding about destruction types and destructive modes for all kinds of buildings , landforms and terrain is achieved in this paper. |
