A photograph of stencilled words on a footpath on Peterborough Street. The words read, "On Peterborough Street the houses are wonky. The ground has been pulled out from underneath them. The trick worked and the houses stayed up, but they are wonky. If you lived in them you might become wonky too".

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.

The center of the river has slumped and the two banks have moved about a meter closer together which caused this footbridge to be so twisted. There is a suggestion that this be left as a memorial to the earthquake.

The Christchurch Art Gallery is on track to reopen late next year, almost five years after the most devastating of the city's earthquakes put it out of commission. One of the key players in this important next step is Dr Lara Strongman who is the gallery's new senior curator.

The Earthquake Commission is insisting the current model for settling earthquake claims is the right one. That's despite a report from one of the country's largest insurers that says the system is inefficient and is having a significant impact on the timely resolution of claims in Christchurch.

Beverly Forrester farms near Harden which is down the road from Hanmer Springs. Road damage means she's cut off from the outside world, apart from her phone Beverly was caught up in the Christchurch earthquake, so the events of the last 24hrs have been quite trying for her.
