On 25 June 2020, a Mw 6.2 earthquake struck Yutian, Xinjiang, offering us a rare chance to gain insights into its mechanism and implications in the Tibetan extension. We used both descending and ascending Sentinel-1 images to generate coseismic deformation associated with this event, which indicates a typical extensional mechanism with a maximum subsidence displacement of 25 cm and minor uplift. The causative fault constrained with interferometric synthetic aperture radar (InSAR) data based on a finite fault model suggests that the fault plane has a strike of 186.4\u00b0 and westward dip of 64.8\u00b0, and the main rupture is concentrated at a depth of 3.6\u201310.8 km with a peak slip of 0.85 m. Our source model indicates that the 2020 Yutian event ruptured an unknown high-angle blind normal fault with N\u2013S striking. The total released geodetic moment yields 2.69 \u00d7 1018 N\u00b7m, equivalent to Mw 6.23. We used dense interseismic global positioning system (GPS) measurements to reveal an approximate 7 mm\/yr extensional motion in the Yutian region, but it still does not seem large enough to support high local seismicity for normal events within 12 years, i.e., Mw 7.1 in 2008, Mw 6.2 in 2012, and this event in 2020. Combined with Coulomb stress change modeling, we speculate that the seismicity in Yutian is related to the lower lithospheric dynamics.<\/jats:p>","DOI":"10.3390\/rs12183012","type":"journal-article","created":{"date-parts":[[2020,9,16]],"date-time":"2020-09-16T10:30:12Z","timestamp":1600252212000},"page":"3012","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":18,"title":["Normal Faulting in the 2020 Mw 6.2 Yutian Event: Implications for Ongoing E\u2013W Thinning in Northern Tibet"],"prefix":"10.3390","volume":"12","author":[{"given":"Ping","family":"He","sequence":"first","affiliation":[{"name":"Hubei Subsurface Multi-Scale Imaging Key Laboratory, Institute of Geophysics and Geomatics, China University of Geosciences, Wuhan 430074, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8746-8615","authenticated-orcid":false,"given":"Yangmao","family":"Wen","sequence":"additional","affiliation":[{"name":"School of Geodesy and Geomatics, Wuhan University, Wuhan 430079, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3459-7824","authenticated-orcid":false,"given":"Kaihua","family":"Ding","sequence":"additional","affiliation":[{"name":"Faculty of Information Engineering, China University of Geosciences, Wuhan 430074, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Caijun","family":"Xu","sequence":"additional","affiliation":[{"name":"School of Geodesy and Geomatics, Wuhan University, Wuhan 430079, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2020,9,16]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1671","DOI":"10.1126\/science.105978","article-title":"Oblique Stepwise Rise and Growth of the Tibet Plateau","volume":"294","author":"Tapponnier","year":"2001","journal-title":"Science"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"809","DOI":"10.1130\/G20554.1","article-title":"Continuous deformation of the Tibetan plateau from global positioning system data","volume":"32","author":"Zhang","year":"2004","journal-title":"Geology"},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"199","DOI":"10.1130\/GES00217.1","article-title":"Active structures of the Himalayan-Tibetan orogen and their relationships to earthquake distribution, contemporary strain field, and cenozoic volcanism","volume":"5","author":"Taylor","year":"2009","journal-title":"Geosphere"},{"key":"ref_4","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1038\/s41467-018-07312-9","article-title":"Normal faulting and viscous buckling in the Tibetan plateau induced by a weak lower crust","volume":"9","author":"Bischoff","year":"2018","journal-title":"Nat.
