## 5 Discussion
These oscillatory states generate volumetric changes of the surfaces, giving rise to a phase of disturbance of the system (rock massif) that is affected, reducing the resistance of the rocks, which are mostly crystalline (igneous and metamorphic), thus creating planes of weakness that are later exploited by the action of a trigger. In addition to the above, if we take only the sequences of the interferograms that correlate with the dates of the movements, two important aspects are observed. On the one hand, the correlation between the number of events and the total displacement in LOS-descending describes an almost linear trend (Figure 10). This relationship can establish a recurrence of a mass movement as a function of the rate of displacement, clarifying that the number of possible events that can be generated cannot be predicted with this function. At the same time, it is observed that the largest number of movements is associated with a subsidence phase, where the \begin{table}

predominant structural style is of the oblique type associated with the Bucaramanga fault and the Bucaramanga Seismic Nest, as described earlier in the results chapter. For the correlation in LOS-ascending, this linear relationship is not observed, which may be associated with the shape of the field of view of the satellite trajectory and the geometry of the fault plane, especially the stroke of the Bucaramanga fault that is almost parallel to this field of view an aspect that was described in the results chapter (Figure 10). On the other hand, it is generally observed that the average deformation rates are between 18.2 mm and \(-21.1\) mm for LOS-ascending and 13.9 mm and \(-21\) mm for LOS-descending. All these behaviors can be measurement indicators for future events in a real-time tracking of surface deformations.
