Earthquake epicenters are concentrated along an ENE\u2013WSW trending pattern. In this study, we used morphological indexes, including the valley floor width-to-valley floor height ratio (Vf), mountain front sinuosity (Smf), the asymmetry factor index (Af), the drainage basin shape index (Bs), the stream length\u2013gradient index (SL), hypsometric integral (Hi) water drainage systems, and a digital elevation model analysis, to identify the role of tectonics. These indexes were used to define the relative tectonic activity index (RTAI), which can be utilized to distinguish low (RTAI &lt; 1.26), moderate (RTAI = 1.26\u20131.73), and high (RTAI &gt; 1.73) tectonic activity signals all over the study area. Firstly, our results indicate low to medium tectonic activity and general anomaly patterns detected along the major tectonic zones of the study area. Secondly, based on most of the low to medium tectonic activity distributed in the study area and the detected anomalies, we discuss two potential drivers of the seismicity in the Abu-Dabbab area, which are fault-controlled and deep-rooted activities.<\/jats:p>","DOI":"10.3390\/ijgi10110784","type":"journal-article","created":{"date-parts":[[2021,11,17]],"date-time":"2021-11-17T09:16:11Z","timestamp":1637140571000},"page":"784","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":19,"title":["Morpho-tectonic Assessment of the Abu-Dabbab Area, Eastern Desert, Egypt: Insights from Remote Sensing and Geospatial Analysis"],"prefix":"10.3390","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3606-9558","authenticated-orcid":false,"given":"Abdelrahman","family":"Khalifa","sequence":"first","affiliation":[{"name":"Department of Geology, Faculty of Science, Al-Azhar University, Cairo 11651, Egypt"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0384-9061","authenticated-orcid":false,"given":"Bashar","family":"Bashir","sequence":"additional","affiliation":[{"name":"Department of Civil Engineering, College of Engineering, King Saud University, Riyadh 11421, Saudi Arabia"}]},{"given":"Abdullah","family":"Alsalman","sequence":"additional","affiliation":[{"name":"Department of Civil Engineering, College of Engineering, King Saud University, Riyadh 11421, Saudi Arabia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0117-1058","authenticated-orcid":false,"given":"Nazik","family":"\u00d6\u011fretmen","sequence":"additional","affiliation":[{"name":"Climate Geochemistry Department, Max Planck Institute for Chemistry, 55128 Mainz, Germany"}]}],"member":"1968","published-online":{"date-parts":[[2021,11,17]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"183","DOI":"10.1016\/j.tecto.2014.05.023","article-title":"Relative tectonic activity assessment of the Tuz G\u00f6l\u00fc Fault zone; Central Anatolia, Turkey","volume":"630","year":"2014","journal-title":"Tectonophysics"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"176","DOI":"10.1007\/s12665-020-08912-9","article-title":"Evaluation of tectonic activity using morphometric indices: Case study of the Tatra Mts.
