Abstract Using regional leveling and faultcrossing leveling data the crustal vertical deformation has been analyzed before and after Wenchuan Ms8.0 earthquake. The results show that before the earthquake the regional deformation were staged,in detail,its differential elevation and subsidence weakened and the movement of Longmenshan fault turned from active to locked,after the earthquake,the earthquake effect spreaded northeast ward along the Longmenshan fault mainly and the coseismic deformation nearby the after shock region was obvious.
Key words :
Wenchuan Ms8.0 earthquake
faultcrossing leveling
vertical deformation
Longmenshan fault
evolution
