                         ABSTRACT: Spatialization of tectonic intensity in the onshore 
                         portion of the Para{\'{\i}}ba Basin and adjacent crystalline 
                         basement, Northeastern Brazil. Studies conducted in different 
                         geomorphological contexts of the Earth have demonstrated 
                         efficiency in the application of geomorphometric data extracted 
                         from digital elevation models for the identification of terrain 
                         features suggestive of tectonic deformation. This study applies 
                         geomorphometric indices for the evaluation of the tectonic 
                         intensity of sedimentary deposits of the onshore portion of the 
                         Para{\'{\i}}ba Basin and of the adjacent crystalline basement, 
                         northeastern Brazil. The following indices were applied with basis 
                         on digital drainage network and digital elevation model of the 
                         Shuttle Radar Topography Mission (SRTM): slope-length ratio (SL), 
                         asymmetric factor (Af), hypsometric integral (Hi) and mountain- 
                         front sinuosity (Smf). The results enabled to distinguish and to 
                         spacialize classes of tectonic deformation intensity through the 
                         tectonic intensity index (Iat). The data revealed more intense 
                         tectonism in Neogene and Quaternary sedimentary units located in 
                         the northeastern portion of the study area.",
