This study focuses on the western part of the Suleiman Fold-Thrust Belt that comprises two parallel NW\u2013SE oriented faults: Harnai Fault and Karahi Fault. These faults have known thrust components; however, there remains uncertainty about the lateral component of motion. This work presents the new observation of surface deformation using the Small Baseline Subset (SBAS), Interferometric Synthetic Aperture Radar (InSAR) technique on Sentinel-1A datasets to decompose displacement into the vertical and horizontal components employing ascending and descending track geometries. The subsurface structural geometry of this area was assessed using 2D seismic and well data. In addition, geomorphic indices were calculated to assess the relative tectonic activity of the area. InSAR results show that the Karahi Fault has a ~15 mm right-lateral movement for descending and ~10 mm\/for ascending path geometries. The Harnai Fault does not show any lateral movement. Seismic data are in agreement with the InSAR results suggesting that the Harnai Fault is a blind thrust. This work indicates that the block between these two faults displays a clockwise rotation that creates the \u201cbookshelf model\u201d.<\/jats:p>","DOI":"10.3390\/rs13183593","type":"journal-article","created":{"date-parts":[[2021,9,9]],"date-time":"2021-09-09T21:36:58Z","timestamp":1631223418000},"page":"3593","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Neotectonics of the Western Suleiman Fold Belt, Pakistan: Evidence for Bookshelf Faulting"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2774-4814","authenticated-orcid":false,"given":"Sukru O.","family":"Karaca","sequence":"first","affiliation":[{"name":"Department of Earth and Atmospheric Sciences, University of Houston, Houston, TX 77004, USA"},{"name":"Remote Sensing and GIS Division, Department of Geological Research,  Directorate General of Mineral Research and Exploration (MTA), TR-06530 Ankara, Turkey"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6939-6256","authenticated-orcid":false,"given":"Ismail A.","family":"Abir","sequence":"additional","affiliation":[{"name":"School of Physics, Universiti Sains Malaysia, Gelugor 11800, Penang, Malaysia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3848-8190","authenticated-orcid":false,"given":"Shuhab D.","family":"Khan","sequence":"additional","affiliation":[{"name":"Department of Earth and Atmospheric Sciences, University of Houston, Houston, TX 77004, USA"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3948-5482","authenticated-orcid":false,"given":"Erman","family":"Ozsay\u0131n","sequence":"additional","affiliation":[{"name":"Department of Geological Engineering, Hacettepe University, TR-06800 Ankara, Turkey"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1690-9089","authenticated-orcid":false,"given":"Kamil A.","family":"Qureshi","sequence":"additional","affiliation":[{"name":"Department of Earth and Atmospheric Sciences, University of Houston, Houston, TX 77004, USA"}]}],"member":"1968","published-online":{"date-parts":[[2021,9,9]]},"reference":[{"key":"ref_1","first-page":"758","article-title":"Seismic data, geometry, evolution, and shortening in the active Sulaiman fold-and-thrust belt of Pakistan, southwest of the Himalayas","volume":"78","author":"Jadoon","year":"1994","journal-title":"Am.
