Abstract:Badong Ms5.1 earthquake in Hubei province caused various damages involving some of rural buildings,and seismic casualty is appeared in meizoseismic area.Based on the field investigation in the earthquake effected area,in this paper,primary characteristics of the typical damages of this earthquake are summarized.Analysis showed that:The meizoseismal area of Ⅶ degree area,which focused on the town of Badong County rang SongjialiangZi area,was NWSE trending,long axis length of 3.9 km,the minor axis length of 2.4 km,an area of about 7.7 km2.Ⅵ degree area was nearly the whole thing to the long axis of about 21.4 km,minor axis length 13.6 km,area 25.1 km2.The map of seismic intensity are trustworthy.Damages have a greater relationship with the seismic performances of buildings.This buildings of the Three Gorge immigration engineering is largely intact.Initial discussion some relationships of the intensity and faults、karst distribution.
