The old Railway Station clock tower on Moorhouse Avenue with plywood and steel reinforcement covering two sides, a crane hanging over top. The brickwork suffered extensive cracking during the earthquake making it in need for reinforcement. The clock has stopped at around 16:35, the time of the earthquake.

A photograph of Ray Whelan and Mark Osborne, from the Wellington Emergency Management Office, standing at a registration station in Cowles Stadium. The stadium was set up as a Civil Defence Report Centre after the 4 September 2010 earthquake. In the background, members of the Red Cross can be seen.

This paper presents site-specific and spatially-distributed ground-motion intensity estimates which have been utilized in the aftermath of the 2010-2011 Canterbury, New Zealand earthquakes. The methodology underpinning the ground motion intensity estimation makes use of both prediction models for ground motion intensity and its within-event spatial correlation. A key benefit of the methodology is that the estimated 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 standard deviation, with the standard deviation being a function of the distance to nearby observations at 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, which among other things, have been utilized for assessing liquefaction triggering susceptibility of land in residential areas. Secondly, the conditional distribution of response spectral ordinates is obtained at the location of the Canterbury Television building (CTV), which catastrophically collapsed in the 22 February 2011 earthquake. The conditional response spectra provide insight for the selection of ground motion records for use in forensic seismic response analyses of important structures at locations where direct recordings are absent.
