On 18 December 2023, an Mw 6.0 earthquake occurred on the Lajishan\u2013Jishishan fault system (LJFS) in the northeastern Tibetan Plateau, causing serious damage and casualties. The seismogenic fault hosting this earthquake is not well constrained, as no surface rupture was identified in the field. To address this issue, in this study, we use Interferometric Synthetic Aperture Radar (InSAR) data to investigate the coseismic surface deformation of this earthquake and invert both ascending and descending line-of-sight observations to probe the seismogenic fault and its slip characteristics. The InSAR observations show up to ~6 cm surface uplift caused by the Jishishan earthquake, which is consistent with the thrust-dominated focal mechanism. A Bayesian-based dislocation modeling indicates that two fault models, with eastern and western dip orientations, could reasonably fit the InSAR observations. By calculating the coseismic Coulomb failure stress changes (\u2206CFS) induced by both fault models, we find that the east-dipping fault scenario could reasonably explain the aftershock distributions under the framework of stress triggering, while the west-dipping fault scenario produced a negative \u2206CFS in the region of dense aftershocks. Integrating regional geological structures, we suggest that the seismogenic fault of the Jishishan earthquake, which strikes NNE with a dip of 56\u00b0 to the east, may be either the Jishishan western margin fault or a secondary buried branch. The optimal finite-fault slip modeling shows that the coseismic slip was dominated by reverse slip and confined to a depth range between ~5 and 15 km. The released seismic moment is 1.61 \u00d7 1018 N\u00b7m, which is equivalent to an Mw 6.07 earthquake. While the Jishishan earthquake ruptured a fault segment of approximately 20 km, it only released a small part of the seismic moment that was accumulated along the 220 km long Lajishan\u2013Jishishan fault system. The remaining segments of the Lajishan\u2013Jishishan fault system still have the capability to generate moderate-to-large earthquakes in the future.<\/jats:p>","DOI":"10.3390\/rs16101746","type":"journal-article","created":{"date-parts":[[2024,5,15]],"date-time":"2024-05-15T06:14:42Z","timestamp":1715753682000},"page":"1746","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":20,"title":["Fault Kinematics of the 2023 Mw 6.0 Jishishan Earthquake, China, Characterized by Interferometric Synthetic Aperture Radar Observations"],"prefix":"10.3390","volume":"16","author":[{"given":"Xing","family":"Huang","sequence":"first","affiliation":[{"name":"State Key Laboratory of Earthquake Dynamics, Institute of Geology, China Earthquake Administration, Beijing 100029, China"}]},{"given":"Yanchuan","family":"Li","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Earthquake Dynamics, Institute of Geology, China Earthquake Administration, Beijing 100029, China"}]},{"given":"Xinjian","family":"Shan","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Earthquake Dynamics, Institute of Geology, China Earthquake Administration, Beijing 100029, China"}]},{"given":"Meijiao","family":"Zhong","sequence":"additional","affiliation":[{"name":"Seismological Bureau of Gansu Province, Lanzhou 730000, China"}]},{"given":"Xuening","family":"Wang","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Earthquake Dynamics, Institute of Geology, China Earthquake Administration, Beijing 100029, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4536-7749","authenticated-orcid":false,"given":"Zhiyu","family":"Gao","sequence":"additional","affiliation":[{"name":"Faculty of Geomatics, Lanzhou Jiaotong University, Lanzhou 730700, China"}]}],"member":"1968","published-online":{"date-parts":[[2024,5,15]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"233","DOI":"10.1146\/annurev-earth-060614-105302","article-title":"From geodetic imaging of seismic and aseismic fault slip to dynamic modeling of the seismic cycle","volume":"43","author":"Avouac","year":"2015","journal-title":"Annu.
