Co- and post-seismic vertical displacements of the Wenchuan earthquake derived from two measurements in 2008 and 2010 along two partly-damaged leveling lines near the epicenter show the following features: Co-seismic displacement at Beichuan-Yingxiu fault was as large as 4.711 m near Beichuan, where the maximum observed fault offset was 5.1 m. In contrast, the observed co-seismic offset of the Qingchuan fault in Pingwu County was only 0. 064 m. During 2008 -2010, the post-seismic displacement rate was 5 -27 mm/a near Beichuan-Yingxiu fault in Beichuan area, 20.6 mm/a at Jiangyou-Guangyuan fault near Dakang, and only 0.2 - 1.3 mm/a at Qingchuan fault near Gucheng.
