Abstract
Knowledge of the earthquakes along the active tectonic structure is fundamental to comprehend the mechanics of continental plates margins and to approximate the earthquake potential in tectonic settings of area of interest. On 22nd January, 2024, an earthquake with magnitude Mw 7 struck in the area located 136 km west of Aksu, China. Tectonically, it occurred in the northwestern vicinity of South Tianshan Thrust Fault (STTF) and at the event location south end the Trim basin exits. This event has added opportunity to understand active tectonics on western edge of STTF. Utilizing the advantage of precise quantification of Interferometric Synthetic Aperture Radar (InSAR) interferometry technique, coseismic deformation, slip distribution and associated of the 22nd Jan, 2024 Mw 7 Uqturpan, China earthquake are estimated. The ascending and descending LOS displacement are measured approximately 150 mm and 100 mm respectively. We find that a fault with strike ~229.84°, dip ~58.55°, and rake ~47.13° is the optimal source, whereas best fit uniform slip is estimated 3.1m concentrated between 3 and 7 km depth approximately. The rupture length and width are estimated approximately 36 km and 11 km respectively, corresponding to Mw 7.1. Using the geometry of uniform model, detailed slip distribution of the model is inverted. The rupture area of the earthquake is calculated 50 km x15 km, concentrated between 2 km and 9 km depth with a maximum slip of 4m. At the end, we simulate the provided the optimally oriented target fault geometry and shows that early aftershocks are quite consisted with the increased ΔCFS
