Blick, G.H. 1977 Whataroa site report (Alpine Fault). Lower Hutt: New Zealand Geological Survey. New Zealand Geological Survey report EDS 8 19 p., figs


Abstract: Three sites, installed and surveyed in January-February, 1972, straddle the Alpine Fault which follows the western side of the Southern Alps, The sites form part of a developing network set up to monitor vertical and horizontal secular deformation throughout New ZealandÂ’s active belt, After the second survey, due to be made within one year of the initial survey, the pattern will be resurveyed every three to five years unless abnormal deformation is suspected, in which case the interval between surveys would be decreased, The first edition of this report was written in 1973 and has been amended in this third edition to present site details of the pattern found to be best during January 1977.
