A demon mask hangs from a brick chimney in New Brighton. Some of the bricks at the base of the chimney appear to have moved. The photographer comments, "Since the September earthquake brick chimneys have been tumbling down. I do not know if this was put up to ward off shaking of the chimney during earthquakes, but it seems to be working. This chimney has now been taken down at the end of March 2012 and replaced with a simple metal flue".

Christchurch city experienced a magnitude 7.1 earthquake on September 4, at 4:35 am. The epicentre was 40 km west of the city. It is the most damaging earthquake in New Zealand since the Hawke's Bay earthquake in 1931, but there was no loss of life. It was fortunate the earthquake occurred when the central city streets were deserted, as there ...

Two aluminium drink cans which have split open. The photographer comments, "We had around 24 cans of diet coke in the top of the fridge when the devastating 6.1 earthquake hit Christchurch in New Zealand. The shaking caused one of the front feet of the fridge to fold, which made the fridge tip forward and causing the door to open. After all the shaking the cans had already when they flew out and hit the ground a lot of them exploded. These two cans show the explosive pressure that occurred best".

A motion-blurred photograph of houses, with the Port Hills in the background. The photographer comments, "This I hope gives you a feel of what it feels like in an earthquake. When you spend your whole life thinking that you and your home are built on solid ground, it can be quite a shock when you find it is not. You can feel the house shaking like a dog with a toy, rising up violently underneath you or the most gentle form which is when the ground moves gently like a wave moving under a rowing boat. It is not just the movement, you often get a rumbling sound which can precede a violent shake or can result in no movement at all. This means that some vehicles can sound like the rumbling initially and in the early days would get your heart racing. Another form of stress is when big excavators as heavy as a tank move as you can feel the ground shake from streets away, but you do not always hear the engine. For most of us the problem when the shaking starts, is wondering if this is the start of an extremely violent earthquake or will it peter out".

Christchurch residents will gather today to mark the 10 year anniversary of the Christchurch Earthquake. Large crowds are expected from half past twelve this afternoon on the lawn just across the river from the memorial wall where a service begin at 12.30. Among those speaking is the prime minister, Jacinda Ardern. A message from former mayor, Sir Bob Parker, will be also read out. The names of the 185 who died will be read before a minute's silence at twelve fifty one, the exact moment the quake struck. Flowers will then be laid at the memorial wall. This is where our coverage began .A warning this is confronting audio of events that day.

The University of Canterbury Dept. of Chemistry has weathered the Canterbury Earthquake of September 4, 2010 very well due to a combination of good luck, good planning and dedicated effort. We owe a great deal to university Emergency Response Team and Facilities Management Personnel. The overall emergency preparedness of the university was tested to a degree far beyond anything else in its history and shown to be well up to scratch. A strong cooperative relationship between the pan-campus controlling body and the departmental response teams greatly facilitated our efforts. Information and assistance was provided promptly, as and when we needed it without unnecessary bureaucratic overheads. At the departmental level we are indebted to the technical staff who implemented the invaluable pre-quake mitigation measures and carried the majority of the post-quake clean-up workload. These people put aside their personal concerns and anxieties at a time when magnitude-5 aftershocks were still a regular occurrence.

An extensive research program is on-going at the University of Canterbury, New Zealand to develop new technologies to permit the construction of multi-storey timber buildings in earthquake prone areas. The system combines engineered timber beams, columns and walls with ductile moment resisting connections using post-tensioned tendons and eventually energy dissipaters. The extensive experimental testing on post-tensioned timber building systems has proved a remarkable lateral response of the proposed solutions. A wide number of post-tensioned timber subassemblies, including beam-column connections, single or coupled walls and column-foundation connections, have been analysed in static or quasi-static tests. This contribution presents the results of the first dynamic tests carried out with a shake-table. Model frame buildings (3-storey and 5-storey) on one-quarter scale were tested on the shake-table to quantify the response of post-tensioned timber frames during real-time earthquake loading. Equivalent viscous damping values were computed for post-tensioned timber frames in order to properly predict their response using numerical models. The dynamic tests were then complemented with quasi-static push and pull tests performed to a 3-storey post-tensioned timber frame. Numerical models were included to compare empirical estimations versus dynamic and quasi-static experimental results. Different techniques to model the dynamic behaviour of post-tensioned timber frames were explored. A sensitivity analysis of alternative damping models and an examination of the influence of designer choices for the post-tensioning force and utilization of column armouring were made. The design procedure for post-tensioned timber frames was summarized and it was applied to two examples. Inter-storey drift, base shear and overturning moments were compared between numerical modelling and predicted/targeted design values.
