The result of the magnitude 7.1 Christchurch earthquake at 4.35am on September 4th 2010. Taken from Dallington Terrace looking towards Avonside Drive. This pumping station used to be level. When the tide is in that flax bush on the bend appears to be growing from the middle of the river, suggesting the land has slumped about a meter.

The north end of the bridge on Gayhurst Road. During the earthquake, the bridge was forced about 15 centimetres towards the river, the land falling away under the road. Fencing has been placed around the footpath, and the road filled and resealed so that it can still be used by traffic.

Site-specific and spatially distributed estimation of ground motion intens…

Research papers, University of Canterbury Library

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.
