Besides the possible economic implications, increased human activity in the region situated northeast of Manaus, drained by rivers Uatumã, Preto da Eva, Urubu, Anebá and Jatapu, tributaries of the left margin of the Amazon River, shows the importance of understanding the framework neotectonic to assess the stability of the area and geological seismic risks involved. This knowledge, besides essential to the petroleum geology, is also relevant to understanding of the trigger mechanisms of geomorphological processes, such as mass movements and erosion.The availability of data from the RADARSAT-2, such as the digital terrain models (DEM), interferometric (InSAR) and polarmetric, besides use of landscape modelling, such as fractal geometry, open new possibilities in the study of geomorphic processes, mainly, the possibility of the use of quantitative approaches. The technicals of interferometric Synthetic Aperture Radar (InSAR), as the differential interferometry (D-InSAR), which is the measurement of successive phase of SAR images to infer the differential interval or change this range, can detect subtle changes in terrain and thus, to generate an understanding of the rheologic response and other phenomena of the earth's crust. Approaches related to fractal geometry enable the analysis of the roughness of digital elevation models in different regions and thus estimate domains of action erosion rates possible and associated denudation rates possible in different lengths of waves. Such methods also offer the possibility of quantitative measures of patterns of morphological lineaments. Thus, such techniques may offer new information on the recent tectonic activity in the region as well as aid in the identification of favourable sites to hydrocarbon prospect, reducing the costs involved in a exploratory campaign, especially in areas of dense vegetation cover as the Amazon.
