Located in the western limb of the Western Ranges of the Colombian Andes. The fault puts Cretaceous mafic igneous rocks to the east in contact with Tertiary marine sedimentary rocks to the west. The fault cuts mud flows dated at about 10,000 to 15,000 years. It causes strong lineaments and offsets terraces and alluvial deposits. The fault forms well-developed scarps of about high on late Quaternary alluvial deposits.
The fault forms the course of the Penderisco River and cuts perpendicular to the Ocaidó Valley. Some authors consider the fault the southern part of the Murrí-Mutatá Fault.Maps
