## 1 Introduction
The processing of this type of images by means of the DInSAR technique has been highly versatile in different fields of study, such as, for example, in the estimation of the deformation generated by the co-seismic effect [7; 13; 14; 15; 16], in the measurement of the deformation and velocity of the glacier mass [17; 18; 19], in the study of volcanic deformation [20; 21; 22], in the analysis of landslides [8; 23; 24; 25] and in studies related to subsidence caused by mining activity, specifically on the effects of water extraction in aquifers or geothermal energy [26; 27; 28]. Depending on what kind of study is to be carried out on the conditions of the environment, the focus of the interferometric analysis will be directed toward those conditions. As described by [PERSON] [1], for earthquake, fault and tectonic studies, interferometric analysis gives the ability to measure the deformation of surfaces by their uplift and subsidence zones (faults and tectonics), or in the pre-seismic, co-seismic and post-seismic phases, in terms of surface deformation (uplifted and sunken region). In turn, these conditions can be extrapolated to the study of volcanic activity in the case of an eruption, following pre-eruptive, co-eruptive and post-eruptive deformation. Furthermore, they can be used in the study of land subsidence caused by mining activities for water, gas, and oil extraction, where the rates of subsidence of the surfaces are observed, or the study of the dynamics of glaciers, where the rate of movement of glaciers and ice in the order of meters is estimated, as well as their velocity. With this panorama, the study of the degrees of surface deformation from the time series of differential interferograms is a powerful tool that allows us to determine these rates of change, giving key points or states of deformation that can be associated with endogenous (tectonic) factors specific to a study region. If this is placed in the context of the present research, estimating these surface changes in terms of deformation can provide a tool for the dynamic behavior of this surface derived from tectonic activity. In this way, important elements can be provided for inclusion within the management of resources or for the planning and ordering of the territory, since possible causes such as mass movements and their effects can be correlated in a coherent way. This approach is established because the technique used (SBAS) is suitable for carrying out studies to measure and detect deformation with a non-linear variation in time, which is an important characteristic that is also shared by mass movements, since they do not have a linear behavior in space and time [29; 30; 31; 32]. In this sense, these tectonic and structural aspects are framed in regional terms, mainly by the tectonic environment of the Bucaramanga Seismic Nest and regional faults, such as the Bucaramanga Fault, which may be creating surface deformation contrasts due to their activity. [PERSON] [33] put forward his mechanical model of the \"Elastic Rebound\", in which it is described that the accumulation of great forces in certain preferential areas of the Earth's crust generates increasingly greater elastic deformations of the rocks until the resistance of these rocks is exceeded, concurrently giving an almost instantaneous release of the accumulated energy; as a result, a seismic wave is generated that creates different states of deformation, giving way to the formation of fracture planes or faults, often visible on the surface. This approach is due to the fact that, in recent years, the number of mass movement events has increased in the study region, and these have generated substantial economic losses in infrastructure and also claimed human lives. At the same time, in previous studies carried out by the Colombian Geological Service (SGC), it has been described regionally that for the present region, there are conditions of high hazard due to mass movements, where rainfall and/or seismic activity are the greatest precursors [34; 35].
