| Abstract: | Co-and post-seismic vertical displacements of the Wenchuan MS8.0 earthquake,derived from pre-seismic leveling data and two measurements in 2008 and 2010 along two first-order leveling lines near Beichuan,show the following features:Co-seismic displacement along 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.From 2008 to 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. |
