Abstract:This paper analyzes the GPS section deformation and strain accumulation of the Eastern Haiyuan fault and the Western Liupanshan fault with three episodes of GPS velocity field data, recorded between 2007-2013. We undertake a comparative analysis of three properties: compression, tension and slip. The results show that, first, the Eastern Haiyuan fault and the Western Liupanshan fault have the same movement style. Second, in the past 10 years, these active faults’ main campaign feature is mainly a left rotation, and pressure changes are minor. In terms of the relative motion differences rate between the upper and the under plates, the measure range is 2.0-5.5 mm/a in the slip direction, and 0.5-3.0 mm/a in the vertical direction.
