This paper presents a methodology by which both site-specific and spatially distributed ground motion intensity can be obtained immediately following an earthquake event. The methodology makes use of both prediction models for ground motion intensity and its correlation over spatial distances. A key benefit of the methodology is that the ground motion intensity at a given location is not a single value but a distribution of values. The distribution is comprised of both a mean and also standard deviation, with the standard deviation being a function of the distance to nearby strong motion stations. The methodology is illustrated for two applications. Firstly, maps of conditional peak ground acceleration (PGA) have been developed for the major events in the Canterbury earthquake sequence. It is illustrated how these conditional maps can be used for post-event evaluation of liquefaction triggering criteria which have been adopted by the Department of Building and Housing (DBH). Secondly, the conditional distribution of response spectral ordinates is obtained at a specific location for the purposes of determining appropriate ground motion records for use in seismic response analyses of important structures at locations where direct recordings are absent.

Shows in six cameos the Mayor of Christchurch, Bob Parker and his wife, Jo Nicholls Parker, wining and dining in six different places, including Christchurch. Context: Christchurch mayoress Jo Nicholls-Parker will add "real value" to a planned series of ratepayer-funded overseas trips, Mayor Bob Parker says. Councillors will discuss whether to approve regular visits by the mayor and mayoress to Christchurch's sister cities and "other strategic partners".
