Description
The 21.7 km Montenegro Fault is part of the Romeral Fault System, running through the western slope of the Central Ranges. The fault is located to the west of the city of Armenia. The fault crosscuts and deforms the Pleistocene volcanic and volcano-sedimentary deposits of the Quindío Fan (Abanico del Quindío), which covers about 400 km2.

The Montenegro Fault forms outstanding fault scarps as much as 60 m in height, beheaded streams, hanging valleys, ponded alluvium, aligned and offset drainages, as well as soil and rock slides on the face of the scarps. The fault deforms Quaternary volcanic debris flows and ash deposits. The Espejo River follows the strike of the Montenegro Fault.
