The
Rivera Transform Fault, also referred to as the
Rivera Fracture Zone, is a right lateral-moving (dextral)
transform fault which lies along the seafloor of the
Pacific Ocean off the west coast of
Mexico just south of the mouth of the
Gulf of California. It runs between two segments of the
East Pacific Rise, forming the southwest boundary of the small
Rivera Plate. The fault is broken into two segments, bisected by a short rifting zone.
