A photograph of the Greendale Fault line, now visible across a paddock due to cracks caused by the 4 September 2010 earthquake.
This originally straight farm fence has been laterally displaced at least 2 metres where it crosses the previously unknown Greendale Faultline from which the Saturday 4 September 2010 earthquake originated.

Another wrestler, representing 'Other faults' appears in the distance yelling 'Is it my turn yet?' Context - Christchurch has now had three major earthquakes and thousands of aftershocks. It now appears likely that the Christchurch quakes resulted from activity on a fault extending directly eastward from the Alpine fault that remained unknown until last year, says Roger Musson, a seismologist at the British Geological Survey in Edinburgh. The new fault first came to light last September (4th) when a stronger but less calamitous quake shook Darfield, 40 kilometres west of Christchurch. Musson says the latest quake (Feb 22, 2011) probably resulted from an eastward continuation of activity on the same fault. "It has probably not moved for tens of thousands of years, so lots of strain built up," says Musson. The third major quake happened on 13th June 2011. (New Scientist - February 22, 2011)

Under the caption, young people carrying their baggage flutter into the air, away from Canterbury and toward 'Oz'.
In September GNS Earth Sciences reported that after the earthquakes, the Greendale and associated faults were still moving as they settled into a new configuration. At the same time the young were leaving Canterbury (and New Zealand) for a better future in Australia. The population of New Zealand was moving into a new configuration.
