The near-field InSAR measurements provide good constraints on the shallow slip distributions (&lt;6 km). The accelerogram data enable us to better resolve the deeper coseismic slip (&gt;6 km). The combination of two types of data provided improved constrains on slip distribution of the 2022 Menyuan earthquake. The results from joint inversion of InSAR and accelerogram data reveal a 26-km-long rupture length, which roughly agrees with the mapped length from the optically identified surface rupture trace and the InSAR deformation field. We imaged a major asperity with a dimension of 14 \u00d7 6 km at 4 km depth updip of the hypocenter. The maximum slip is estimated to be 3.8 m at 4 km depth. The duration of the 2022 Menyuan earthquake is ~14 s, and 90% of the seismic moment is released in the first 10 s. The total seismic moment is estimated to be 1.31 \u00d7 1 \u00d7 1019 N\u00b7m, equivalent to a moment magnitude of Mw6.7. Our results highlight that the moderate but shallow rupture during the 2022 Menyuan earthquake could intensify the seismic damage on the surface, confirmed by field investigations.<\/jats:p>","DOI":"10.3390\/rs14205104","type":"journal-article","created":{"date-parts":[[2022,10,12]],"date-time":"2022-10-12T22:45:29Z","timestamp":1665614729000},"page":"5104","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["Rupture Process of the 2022 Mw6.6 Menyuan, China, Earthquake from Joint Inversion of Accelerogram Data and InSAR Measurements"],"prefix":"10.3390","volume":"14","author":[{"given":"Chuanchao","family":"Huang","sequence":"first","affiliation":[{"name":"State Key Laboratory of Earthquake Dynamics, Institute of Geology, China Earthquake Administration, Beijing 100029, China"},{"name":"School of Earth Sciences, Yunnan University, Kunming 650091, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6142-3942","authenticated-orcid":false,"given":"Guohong","family":"Zhang","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Earthquake Dynamics, Institute of Geology, China Earthquake Administration, Beijing 100029, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0905-4553","authenticated-orcid":false,"given":"Dezheng","family":"Zhao","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":"Chaodi","family":"Xie","sequence":"additional","affiliation":[{"name":"School of Earth Sciences, Yunnan University, Kunming 650091, China"}]},{"given":"Hongwei","family":"Tu","sequence":"additional","affiliation":[{"name":"Seismological Bureau of Qinghai, Qinghai 810001, China"}]},{"given":"Chunyan","family":"Qu","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Earthquake Dynamics, Institute of Geology, China Earthquake Administration, Beijing 100029, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5898-8662","authenticated-orcid":false,"given":"Chuanhua","family":"Zhu","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Earthquake Dynamics, Institute of Geology, China Earthquake Administration, Beijing 100029, China"},{"name":"Guangdong Key Laboratory of Urban Informatics and Guangdong Laboratory of Artificial Intelligence and Digital Economy (SZ), School of Architecture & Urban Planning, Shenzhen University, Shenzhen 518000, China"}]},{"given":"Nana","family":"Han","sequence":"additional","affiliation":[{"name":"Seismological Bureau of Shanghai, Shanghai 200062, China"}]},{"given":"Junxian","family":"Chen","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Earthquake Dynamics, Institute of Geology, China Earthquake Administration, Beijing 100029, China"}]}],"member":"1968","published-online":{"date-parts":[[2022,10,12]]},"reference":[{"key":"ref_1","first-page":"256","article-title":"Surface rupture characteristics of the Menyuan, M.6.9 earthquake on January 8, 2022, Qinghai Province","volume":"44","author":"Liang","year":"2022","journal-title":"Seismol.
