The Awatere Fault is an active dextral (right lateral) strike-slip fault in the northeastern part of South Island, New Zealand. It forms part of the Marlborough fault system, which accommodates the transfer of displacement along the oblique convergent boundary between the Indo-Australian plate and Pacific plate, from the transform Alpine Fault to the Hikurangi Trough subduction zone.[1] The 1848 Marlborough earthquake was caused by rupture of the whole of the eastern section of the Awatere Fault.[2] The 175 km (109 mi) long Awatere Fault is formed of two main segments; the Molesworth section to the southwest and the Eastern section to the northeast.[3] A further strand links the southwestern end of the Eastern section to the Clarence Fault, passing through Barefell Pass.[4]
