The Abriaquí Fault (Spanish; Castilian: Falla de Abriaquí) is an oblique thrust fault in the department of Antioquia in northwestern Colombia. The fault has a total length of 33.8km (21miles) and runs along an average northwest to southeast strike of 311 ± 2 in the Western Ranges of the Colombian Andes.
The fault is named after Abriaquí.[1]
The Abriaquí Fault parallels the Cañasgordas Fault to the south, cutting Cretaceous oceanic volcanic rocks as well as Tertiary and Cretaceous sedimentary rocks. The fault has a well defined fault trace with scarps, saddles, and deflected streams. The slip rate is estimated at 0.2mm1mm per year deduced from displaced geomorphologic features.[1]
