Abstract After the Wenchuan \%M\%s 8.0 earthquake, the First and Second Crust Monitoring and Application Centers of China Earthquake Administrator measured two first order leveling lines from Pingwu to Beichuan to Mianzhu, which is of 201.8 km, and from Guixi to Jiangyou, which is of 35.6 km,respectively. By processing and analyzing the leveling data before and after the earthquake, we calculated the coseismic vertical displacement and obtained some results as follows. 1)The coseismic vertical displacement in Qingchuan fault near the ancient urban of Pingwu caused by Wenchuan \%M\%s 8.0 earthquake is small as the relative vertical displacement between the hanging wall and foot wall of the Qingchuan fault is 0.064 m and the Qingchuan fault shows thrust fault properties.2)The coseismic vertical displacement in BeichuanYingxiu fault near Beichuan caused by Wenchuan \%M\%s 8.0 earthquake is large, the maximum vertical displacement is 4.711 m and the relative vertical displacement of the BeichuanYingxiu fault is 5.100 m, the BeichuanYingxiu fault shows thrust fault properties too.3)The coseismic vertical displacement in BeichuanYingxiu fault near Guixi is about 2.440 m.4)The coseismic vertical displacement in JiangyouGuangyuan fault about 12 km northwards from Jiangyou is small as, the relative vertical displacement of the JiangyouGuangyuan fault is 0.101 m.5)The coseismic vertical displacement in BeichuanYingxiu fault near Nanba in Pingwu is relative large as the relative vertical displacement of the BeichuanYingxiu fault is 1.381 m, the Qingchuan fault shows thrust fault properties.
