This paper examines the consistency of seismicity and ground motion models, used for seismic hazard analysis in New Zealand, with the observations in the Canterbury earthquakes. An overview is first given of seismicity and ground motion modelling as inputs of probabilistic seismic hazard analysis, whose results form the basis for elastic response spectra in NZS1170.5:2004. The magnitude of earthquakes in the Canterbury earthquake sequence are adequately allowed for in the current NZ seismicity model, however the consideration of ‘background’ earthquakes as point sources at a minimum depth of 10km results in up to a 60% underestimation of the ground motions that such events produce. The ground motion model used in conventional NZ seismic hazard analysis is shown to provide biased predictions of response spectra (over-prediction near T=0.2s , and under-predictions at moderate-to-large vibration periods). Improved ground motion prediction can be achieved using more recent NZ-specific models.

Refers to the controversy over the decision to demolish the Christchurch Cathedral which was severely damaged in the earthquakes of 2010 and 2011. The Anglican Bishop of Christchurch Victoria Mathews says the decision to demolish the cathedral was reached through prayer, great deliberation and with the utmost concern for safety. The Bishop says a number of options were considered before deciding to bring the walls down but the turning point was 23 December 2011, when a series of strong quakes rocked the city. At that stage the Canterbury Earthquake Authority approached the church. "CERA told us that our plans for making safe and retrieving, and then stepping back and making further decisions were no longer adequate." Christchurch City council announced their support on Twitter this afternoon (17 May 2012) - tweeting an endorsement to an immediate pause on demolition of the Cathedral to enable deeper and more open consideration of options.

The song 'Antartica' is the latest offering from nine-year-old Christchurch songwriter Bob Gaudin. It's not the first song he's had released - in fact it's the third. He wrote his first song - a one minute thirty second symphony - when he was seven about the Christchurch earthquake, which was played and recorded by the NZ Symphony Orchestra!
