This paper describes an analysis of damage costs to house and farm property in the Ms = 6.6 Edgecumbe New Zealand earthquake of 2 March 1987. The study investigated damage ratios for dwellings, plus their associated garages and farm buildings. The damage costs were converted to damage ratios, by dividing them by the total value of the relevant property in the intensity zones concerned. The mean values and statistical distributions of these damage ratios were then found, the lognormal distribution fitting very well. The mean damage ratio for house buildings at MM intensity IX was 0.08, and the mean damage ratios were generally smaller than previous studies had shown.
