The fault is located in the northwest corner of the country. It extends through the Sinú Valley and passes close to the city of Montería. The fault places upper Tertiary rocks of the Sinú Belt (to the west) against lower Tertiary rocks of the San Jacinto Belt (to the east). To the north, the fault is covered by young alluvial deposits.[1]
