The Eltanin Fault System (Eltanin Fracture Zone) is a series of six or seven dextral transform faults that offset the Pacific-Antarctic Ridge, a spreading zone between the Pacific plate and the Antarctic plate. This is extending by up to 7.93 cm/year (3.12 in/year).[1] It was named after the oceanographic ship USNS Eltanin.[2]
