Abstract

Abstract

The 23 August 1985 Wuqia M_w 6.9 earthquake in Xinjiang Province, represents one of the strongest events in the Pamir-Southern Tian Shan convergence zone during the instrumental period. It was also one of the few events that produced clear coseismic surface rupture in the mountain ousforeland region. Based on previous studies of Feng et al. (1986, 1988) and Ainscoe (2018), in this study, we investigate map-view geometry, deformation patterns, and subsurface fault geometry of the Wuqia coseismic surface rupture, through a combining analysis of post-seismic Worldview satellite images, drone images, as well as fault outcrops from natural and artificial trench exposures. Our study documents that the eastern segment of the surface rupture exhibits an arcuate shape overall, and its strike, slip sense, and underlying fault dip have a significant variation along the fault. Comparatively, the western segment has more constant trending, slip sense, and underlying fault dip along the fault, even though it is quite discontinuous due to erosion of post-seismic surface process. Given that the eastern and western segments of the surface rupture lies at the southern and northern sidesof a synclinal hinge at Mingyaole southern limb, respectively, we suggest that such contrasting deformation pattern is dominantly controlled by the inherited folding-related structures of the Mingyaole fold (i.e., flexural-slip faults formed during the Mingyaole folding deformation).
