Abstract
    Available conventional and swath-bathymetric data combined with earthquake slip vectors suggest the existence of three discrete linear segments along the Rivera Fracture Zone. Comparisons of these segments with small circles about various present-day Euler poles show that the Rivera Fracture Zone is not a transform fault, as it is currently accepted, but rather an accommodation zone between two different spreading systems. We suggest that the Pacific-Rivera Rise and the western segment of the Rivera Fracture Zone (trending N54 degree W), are parts of the Pacific-North America plate boundary. The central segment (trending N72 degree W) and the eastern segment (trending N85 degree W) belong to a diffuse boundary connecting the Pacific-North America plate boundary to the East Pacific Rise system.
