the el tigre fault is a 120 km long, roughly north-south trending, major strike-slip fault located in the western precordillera in argentina. the precordillera lies just to the east of the andes mountain range in south america. the northern boundary of the fault is the jáchal river and its southern boundary is the san juan river. the fault is divided into three sections based on fault trace geometry, northern extending between 41–46 km in length, central extending between 48–53 km in length, and southern extending 26 km in length. the fault displays a right-lateral (horizontal) motion and has formed in response to stresses from the nazca plate subducting under the south american plate. 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.
