Abstract Combining the other data cross Longmenshan fault,we have made a frech analysis of the shortline leveling at Gengda before and after the Wenchuan earthquake.It is found that the change of the shortline leveling was caused by construction of living houses in the locality,but earthquake pracursory anomaly.
Key words ：
crustal deformation
faultcrossing survey
tectonic movement
leveling anomaly
Wenchuan earthquake
