321:. Research models in the 1980s describe the fault as system anywhere from 800 km up to 1000 km in length. The kinematics, geometry, extension, and deformation have not been widely agreed upon, therefore the new interest in the El Tigre Fault should lead to further studies using modern technology. These future studies should shed light on the discrepancies that have resulted from lack of in depth information in the past.
86:. It is a major fault with crustal significance. The Andes Mountain belt trends with respect to the Nazca Plate/South American Plate convergence zone, and deformation is divided between the Precordilleran thrust faults and the El Tigre strike-slip motion. The El Tigre Fault is currently seismically active.

The northern subdivision is approximately 41–46 km long. One estimation shows the segment begins where the fault bends to the northeast and is 41 km long. Another estimation places the distinction 5.5 km south of this bend resulting in the northern segment 46 km long. This section

in this segment, some studies conclude a horizontal displacement rate of approximately 1 mm/yr. The southern segment along with the central segment are crossed by several oblique and transverse faults almost perpendicular to the El Tigre Fault. These faults are inferred due to the long linear

The termination point for El Tigre in the south is recognized by a merging within the Precordilleran Paleozoic strata, as well as its extremely disturbed surface deformation. By dating the

The faults location in a seismically active zone and a low erosional environment makes it a good study area. Although many characteristics of geomorphology have been preserved, the area has not been extensively studied using the new methodologies currently available. The fault has sparked new
