In field investigation, the authors found that Qinghai Yushu Ms7.1 earthquake occurred on April 14, 2010 produced a ~65 km long co-seismic surface rupture zone which strikes 310° and dips NE. The entire zone is composed of two parts: the west section is about 19 km long and the east section is 30 km. Between these two sections, a 15 km long zone surface rupture gap is observed. Surface ruptures displayed common sinistral lines mainly featuring right stepping en-echelon ruptures, while vertical offsets developed. The authors conclude that we need 1 800~2 600 earthquakes similar to Yushu earthquake to form Yushu Nanshan. Former researchers reckon the recurrence period of the Yushu section of Ganzi-Yushu fault zone to be 120~200 years, which would make us believe that this fault section’s activity started from 200~400 ka ago.
