Why is the Royal Commission into Building Collapses in the Christchurch Earthquake not apportioning blame? Christchurch lawyer Grant Cameron represented the victims of the Cave Creek Tragedy.
The families of some of those killed by falling rubble in February's Christchurch earthquake are desperate to know why buildings that had been deemed safe collapsed.
An engineer who worked for the company that designed the CTV building, has criticised the attitude of his former boss at the Canterbury Earthquakes Royal Commission.

Over 6.3 million waste tyres are produced annually in New Zealand (Tyrewise, 2021), leading to socioeconomic and environmental concerns. The 2010-11 Canterbury Earthquake Sequence inflicted extensive damage to ~6,000 residential buildings, highlighting the need to improve the seismic resilience of the residential housing sector. A cost-effective and sustainable eco-rubber geotechnical seismic isolation (ERGSI) foundation system for new low-rise buildings was developed by the authors. The ERGSI system integrates a horizontal geotechnical seismic isolation (GSI) layer i.e., a deformable seismic energy dissipative filter made of granulated tyre rubber (GTR) and gravel (G) – and a flexible rubberised concrete raft footing. Geotechnical experimental and numerical investigations demonstrated the effectiveness of the ERGSI system in reducing the seismic demand at the foundation level (i.e., reduced peak ground acceleration) (Hernandez et al., 2019; Tasalloti et al., 2021). However, it is essential to ensure that the ERGSI system has minimal leaching attributes and does not result in long-term negative impacts on the environment.
Panellists Neil Miller and Zoe George discuss a breakthrough in multi-storey buildings for earthquakes with Ben Moerman, a PHD student from the University of Canterbury studying Civil Engineering.
People caught up in February's earthquake in Christchurch want to know why a Royal Commission of inquiry isn't going to apportion any blame for building collapses.
Survivors of February's devastating earthquake in Christchurch are astounded the Royal Commission won't investigate whether anyone should be held liable for the collapse of so many central city buildings.
Scientists in Europe have developed a technology which could be used to find survivors buried in rubble from collapsed buildings in events like the Christchurch and Japanese earthquakes.

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 lawyer for the man whose company designed the CTV building says it was the strength and number of Canterbury earthquakes that caused its collaspe, and not any design faults.
