Awatere Fault

This section has an overall strike of N75–80°E, giving local zones of transtension at some of the segment boundaries, such as at Isolated Flat.

[5] The Eastern section of the fault runs from Molesworth Station to the coast, near White Bluffs, without significant segmentation.

[2]: 375–376 The Molesworth section appears to have moved twice since about 3000 years ago, in events with slip values of about 6–7 m (20–23 ft).

[7] In 1848 a minimum 110 km (68 mi) length section of the fault ruptured, causing an earthquake of an estimated magnitude of about 7.5 Mw.

[2]: 379  The rupture appears to have bypassed the Molesworth section of the fault, continuing on the southern strand through Barefell Pass.
