Cerro Colorado and Curiquinca are aligned in a west-east pattern. Other volcanoes in the area such as Lascar-Aguas Calientes, Licancabur-Juriques and La Torta-Tocorpuri also form such alignments which seem to be controlled by north-south tension in the crust. Sairecabur is located on faults which are also apparent at Laguna Verde.
