Interpretación morfotectónica de la falla Ibagué para su caracterización paleosismológica

The Ibagué Fault is a WSW-ENE right-lateral strike-slip structure located in the central part of the Central Cordillera and in the middle of transverse shear zone that affects the Colombian Andes. Morphotectonic interpretations of the fault from satellite images allow us to propose the style of deformation and the kinematics of the structure. These structural characteristics together with geographical, geomorphologic, sedimentologic and climatic data are key elements for the right selection of a paleoseismical investigation site. The strand appears to be as a single line along the Ibagué Fan at regional scale. However, detailed studies shown several morphotectonic features characteristic of wrench tectonics. Riedel and en-echelon array indicate dextral displacements. Additionally, microtectonic data show a local stress tensor with a s1=311º/18 °±15 ° and a factor R=0,62, indicating a strike-slip regime, which is coherent with the observed geologic and morphotectonic features.
