More specifically, the study area around the Bogot\u00e1-Villavicencio road in the central sector of the Eastern Cordillera is one of the regions with the highest concentration of phenomena, which makes its study a priority. An inventory and detailed analysis of 2506 landslides has been carried out, in which five basic typologies have been differentiated: avalanches, debris flows, slides, earth flows and creeping areas. Debris avalanches and debris flows occur mainly in metamorphic materials (phyllites, schists and quartz-sandstones), areas with sparse vegetation, steep slopes and lower sections of hillslopes; meanwhile, slides, earth flows and creep occur in Cretaceous lutites, crop\/grass lands, medium and low slopes and lower-middle sections of the hillslopes. Based on this analysis, landslide susceptibility models have been made for the different typologies and with different methods (matrix, discriminant analysis, random forest and neural networks) and input factors. The results are generally quite good, with average AUC-ROC values above 0.7\u20130.8, and the machine learning methods are the most appropriate, especially random forest, with a selected number of factors (between 6 and 8). The degree of fit (DF) usually shows relative errors lower than 5% and success higher than 90%. Finally, an integrated landslide susceptibility map (LSM) has been made for shallower and deeper types of movements. All the LSM show a clear zonation as a consequence of the geological control of the susceptibility.<\/jats:p>","DOI":"10.3390\/rs15153870","type":"journal-article","created":{"date-parts":[[2023,8,4]],"date-time":"2023-08-04T09:28:04Z","timestamp":1691141284000},"page":"3870","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Landslide Susceptibility Analysis on the Vicinity of Bogot\u00e1-Villavicencio Road (Eastern Cordillera of the Colombian Andes)"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1543-2186","authenticated-orcid":false,"given":"Mar\u00eda Camila","family":"Herrera-Coy","sequence":"first","affiliation":[{"name":"Department of Cartographic, Geodetic and Photogrammetric Engineering, University of Ja\u00e9n, 23071 Ja\u00e9n, Spain"}]},{"given":"Laura Paola","family":"Calder\u00f3n","sequence":"additional","affiliation":[{"name":"Department of Earth and Marine Sciences (DiSTeM), University of Palermo, 90123 Palermo, Italy"}]},{"given":"Iv\u00e1n Leonardo","family":"Herrera-P\u00e9rez","sequence":"additional","affiliation":[{"name":"Department of Cartographic, Geodetic and Photogrammetric Engineering, University of Ja\u00e9n, 23071 Ja\u00e9n, Spain"},{"name":"Department of Geographic and Environmental Engineering, University of Applied and Environmental Sciences (U.D.C.A.), Bogot\u00e1 111166, Colombia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1812-5613","authenticated-orcid":false,"given":"Paul Esteban","family":"Bravo-L\u00f3pez","sequence":"additional","affiliation":[{"name":"Department of Cartographic, Geodetic and Photogrammetric Engineering, University of Ja\u00e9n, 23071 Ja\u00e9n, Spain"},{"name":"Institute for Studies of Sectional Regime of Ecuador (IERSE), University of Azuay, Cuenca 010107, Ecuador"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7974-7961","authenticated-orcid":false,"given":"Christian","family":"Conoscenti","sequence":"additional","affiliation":[{"name":"Department of Earth and Marine Sciences (DiSTeM), University of Palermo, 90123 Palermo, Italy"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9988-988X","authenticated-orcid":false,"given":"Jorge","family":"Delgado","sequence":"additional","affiliation":[{"name":"Department of Cartographic, Geodetic and Photogrammetric Engineering, University of Ja\u00e9n, 23071 Ja\u00e9n, Spain"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3362-1578","authenticated-orcid":false,"given":"Mario","family":"S\u00e1nchez-G\u00f3mez","sequence":"additional","affiliation":[{"name":"Department of Geology, University of Ja\u00e9n, 23071 Ja\u00e9n, Spain"},{"name":"Natural Hazards Lab of the Centre for Advanced Studies in Earth Sciences, Energy and Environment (CEACTEMA), University of Ja\u00e9n, 23071 Ja\u00e9n, Spain"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6822-775X","authenticated-orcid":false,"given":"Tom\u00e1s","family":"Fern\u00e1ndez","sequence":"additional","affiliation":[{"name":"Department of Cartographic, Geodetic and Photogrammetric Engineering, University of Ja\u00e9n, 23071 Ja\u00e9n, Spain"},{"name":"Natural Hazards Lab of the Centre for Advanced Studies in Earth Sciences, Energy and Environment (CEACTEMA), University of Ja\u00e9n, 23071 Ja\u00e9n, Spain"}]}],"member":"1968","published-online":{"date-parts":[[2023,8,4]]},"reference":[{"key":"ref_1","unstructured":"Turner, A.K., and Schuster, R.L.
