Physical aspects
editLocated in the North flank of the Platanar Volcano, it is composed of at least nine cones, of which one is recognized as a hill (cerro) and the remaining eight as hillocks (loma).[2][3]
The sides of the cones are slanted between 10 and 30 degrees, the cones have an elongated shape in the East to West direction and the complex runs in the North to South direction, evidence of tectonic origin. Previous lava flow activity is appreciated in some of the cones.[2][4]
