![]() This hypothesis was confirmed in a study of the fault plane solutions that showed the slip on transform faults points in the opposite direction than classical interpretation would suggest. Slip along transform faults does not increase the distance between the ridges it separates the distance remains constant in earthquakes because the ridges are spreading centers. The new class of faults, called transform faults, produce slip in the opposite direction from what one would surmise from the standard interpretation of an offset geological feature. Background Geophysicist and geologist John Tuzo Wilson recognized that the offsets of oceanic ridges by faults do not follow the classical pattern of an offset fence or geological marker in Reid' s rebound theory of faulting, from which the sense of slip is derived.

A smaller number of such faults are found on land, although these are generally better-known, such as the San Andreas Fault and North Anatolian Fault. This is a result of oblique seafloor spreading where the direction of motion is not perpendicular to the trend of the overall divergent boundary. Most such faults are found in oceanic crust, where they accommodate the lateral offset between segments of divergent boundaries, forming a zigzag pattern. A transform fault is a special case of a strike-slip fault that also forms a plate boundary. It ends abruptly where it connects to another plate boundary, either another transform, a spreading ridge, or a subduction zone. ![]()
