A prominent semicircular structure bounded by circular normal faults and a northeast‐southwest trending, active normal fault are the main structures identified in Santa Maria Amajac, south central Hidalgo, Mexico, in the Trans Mexican Volcanic Belt. Fieldwork, assisted by a Geographic Information System helped to refine the traces of the identified geologic structures. The field evidences supports our hypothesis that the lacustrine deposits in the area are associated with the evolution of a possible volcanic collapse caldera. Our results are the base for a geological risk map and will shed light on the understanding of the mechanisms that governed the evolution of the suspect collapse caldera. |
