In order to evaluate the possible mechanisms of generation for the Agrio depression, three series of analogue models were performed, simulating transtension, caldera collapse, and transtension followed by collapse. Kinematic indicators were mesured in key locations in the area to compare with the experimental results. The models showed that the generation of a pull-apart induced by an inflection in the main fault is not compatible with the structural arrangement of the depression, and structures within it can be generated without a rotation of the principal stress known for the area.
