Near the center of this photo is Cerro Corero de la Charca, a lava dome that formed at the northern end of a fault-bounded horst about 220,000 years ago within a small crater within El Castillo dome (right). Recent activity at El Castillo occurred on its northern flanks at the intersection of major faults trending NNW, NW, and ENE.
