The Cañasgordas Fault is located to the northwest of the city of Medellín. The fault traverses most of the Western Ranges of the ColombianAndes between the towns of Dabeiba and Giraldo in the department of Antioquia. The Cañasgordas Fault probably joins the Mutatá Fault. The fault displaces Cretaceoussedimentary and volcanic rocks, Tertiary sedimentary rocks, and Quaternarymud flows. The fault forms strong linear features on satellite images and aerial photographs and controls the course of the Río Sucio, which has a prominent, linear V-shaped valley. Fault scarps are formed on Quaternary mud flows.[1] The slip rate is estimated at 0.01 to 0.1 millimetres (0.00039 to 0.00394 in) per year deduced from offset of mud flows and the fault was probably active in the Late Pleistocene.[2]
