Blick, G.H. 1976 Survey report - Woodville 1975. Lower Hutt: New Zealand Geological Survey. New Zealand Geological Survey report EDS 37 16 p.
Abstract: General - The Woodville pattern, straddling the Wellington Fault, was installed by EDS in November 1975 and first surveyed in December 1975. The purpose of this pattern is to monitor secular deformation across the Wellington Fault at regular intervals. A full description of the Woodville site and pattern will be the subject pf a separate report. This report presents detail of the method of surveying and the survey results. A full discussion on the significance of the results in terms of earth deformation is not intended for this report series. Geological setting - The Woodville site straddles the Wellington Fault which separates Mesozoic Greywacke to the north west from Upper Pliocene marine sediments to the south east. The scarp is upthrown to the north west and cuts Recent and Late Otira glaciation deposits. The dominant component is right-lateral and reaches 65 m in post glacial time. Pattern - The pattern consists of five points, A, B, M, Y and Z, which straddle the fault. These points form two overlapping braced quadrilaterals (Fig 1). The pattern is designed to monitor a small section of the fault in a simple and accurate manner using both triangulation and trilateration (auth)
