Recent completion of the Earthquake Risk (Prone) survey of unreinforced masonry buildings in the Gisborne District provides an opportunity to review the results achieved and, bearing in mind the re-draft of the Red Book, reflect on observed behaviour of local buildings in two "moderate" or close to "moderate" earthquakes. This paper gives a brief summary of the results of the Gisborne survey then discusses some of the actual damage sustained by the unreinforced masonry building stock in comparison with ground accelerations recorded in the 1966 "Gisborne" and 1993 "Ormond" earthquakes. Further comparison is made against theoretical loadings as represented by the 1965 and current design codes, and strengths as represented by the "Red Book" and its successor. The paper concludes with comment on the Earthquake Risk (Prone) Buildings survey process and "capture" threshold strength levels to be embodied in future legislative changes.

This report deals with the environment in which the soils occur, the profile characteristics and the agricultural utilization of the soils in terms of the soil series recognized. Information on the field identification of the soils is given under the individual soil series description
