A photograph of a sign taped to the lamp post in front of Sonya Smith Atelier on Colombo Street. The sign reads, "Danger, keep out, restricted area". A yellow sticker on the front door also indicates that access to the building is restricted. A handwritten sign on the door reads, "Cannot open safely until structure is checked. Please ring Sonya if needing any more assistance. Sonya. Keep safe".

'Cappuccino dreams'. Christchurch mayoral candidates Jim Anderton and incumbent mayor Bob Parker tell constituents that they will get respectively more transparency in 'financial dealings' and in 't-shirts'. As the earthquake strikes they continue their electioneering until they are told to 'clear orf' because 'these frames lack substance'. A front-end loader begins to dismantle the structure from which they are speaking. Refers to the local body elections to take place 9th October and the Canterbury earthquake of 4th September.

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.
