Abstract
    Swath bathymetry (SeaBeam) along with available earthquake slip vectors suggest the existence of three distinct rectilinear segments along the Rivera Fracture Zone; these three segments trend differently instead of delineating a continuous smallcircle segment. Therefore, the Rivera Fracture Zone is not a transform fault as currently accepted but an accomodation zone between two diferent spreading systems. The western segment, which trends N52 degree W, belongs to the San Andreas and Gulf of California transform system, the Eastern segment, trending N85 degree W, belongs to the East Pacific Rise system and the Central segment, trending N72 degree W, connects the Western and Eastern segments.
