Suggate, R.P. 1990 Vertical displacement associated with the White Creek Fault accompanying the 1929 Murchison (New Zealand) earthquake. Lower Hutt: New Zealand Geological Survey. New Zealand Geological Survey report EDS 131 23 p.
Abstract: Unpublished data and closer comparison with the geology than in published accounts lead to a new presentation of vertical deformation and its relations to geological structure. Detail of deformation close to the White Creek Fault includes both uplift and downdrop for 0.4 km west of the fault on the downthrown side and diminishing away from it; this may result from differential slip on vertical bedding planes in Tertiary sediments. The maximum recorded uplift was 4.9 m from 0.4 to 1.2 km east of the c. 4.5 m vertical displacement at the fault itself. Initial deformation, from relevelling within 2 months of the 17 June 1929 earthquake, diminished progressively eastwards for 20 km from the fault. Post-earthquake adjustment, at least 0.5 m uplift close to the fault, is thought to have ceased before January 1930. By mid- 1930, probably much earlier, initial uplift was modified by relative downdrop in the section 7.5 to 16 km east of the fault, across the steep east-dipping western flank of the Murchison depression, which carries Tertiary sediments down to -8 km. No uplift took place on the east side of the depression but vertical uplift of c. 0.5 m took place close to a major fault with sheared Tertiary rocks between basement blocks 10 km to the east.
