Due to the extensional regime shaping the region, the system is dominated by normal faulting, most of which is North-South striking and dipping around 60 degrees to the East. Though the system is mostly dip-slip, there are regions of strike-slip formed mylonites in the East providing evidence for

The general strike of the fault system is North-South, though the fault activity varies between the 3 regions of the AFZ. The
Northern region encompasses the Salar del Carmen major fault which splits the region into a Western domain with large active faults striking N160 to N170 and an Eastern

Pacific Ocean. The fault system is North-South striking and runs for more than 1100 km North and up to 50 km in width through the Andean forearc region. The zone is a direct result of the ongoing subduction of the Eastward moving
