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.

Two people stare at a demolition scene. The man thinks there must have been an earthquake but the woman advises him that it was the city council. Refers to plans to demolish three buildings in Wellington's Willis Street without public consultation. The buildings due for demolition are owned by Singaporean Grand Complex Properties, which plans eventually to build a multimillion-dollar high-rise on the site, reports stuff.co.nz. The Canterbury earthquake happened 4th September and as a result there has been a lot of discussion about the need to preserve historic buildings if at all possible. Quantity: 1 digital cartoon(s).

The September Canterbury earthquake. These pictures were taken of Colombo Street in Sydenham. A lot of masonry in this area has been damaged/fallen down. Ascot TV. This has relocated further south on Colombo Street. Apparently their building on Cranford Street was also severely damaged. Note: these photos were taken on a cellphone; mind the qu...
