An overview of the 22 February 2011 Christchurch earthquake is presented in the context of characterization of extreme/rare events. Focus is given to the earthquake source, observed near-source strong ground motions, and effects of site response, while structural response and consequences are mentioned for completeness. For each of the above topics comparisons and discussions are made with predictive models for each of phenomena considered. In light of the observations and predictive model comparisons, the author’s opinion on improving the characterization of such extreme/rare events, and their appropriate consideration in seismic design is presented

Two huge wrestlers, one representing 'Port Hills fault' and the other 'Greendale fault' struggle together over a broken Christchurch. 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.

As part of the 'Project Masonry' Recovery Project funded by the New Zealand Natural Hazards Research Platform, commencing in March 2011, an international team of researchers was deployed to document and interpret the observed earthquake damage to masonry buildings and to churches as a result of the 22nd February 2011 Christchurch earthquake. The study focused on investigating commonly encountered failure patterns and collapse mechanisms. A brief summary of activities undertaken is presented, detailing the observations that were made on the performance of and the deficiencies that contributed to the damage to approximately 650 inspected unreinforced clay brick masonry (URM) buildings, to 90 unreinforced stone masonry buildings, to 342 reinforced concrete masonry (RCM) buildings, to 112 churches in the Canterbury region, and to just under 1100 residential dwellings having external masonry veneer cladding. In addition, details are provided of retrofit techniques that were implemented within relevant Christchurch URM buildings prior to the 22nd February earthquake and brief suggestions are provided regarding appropriate seismic retrofit and remediation techniques for stone masonry buildings. http://www.nzsee.org.nz/publications/nzsee-quarterly-bulletin/

Thousands of Christchurch refugees have poured into Timaru since the earthquake on February 22, boosting its population by nearly 20 per cent. Social services are giving out hundreds of food parcels, blankets, toiletries and clothes every day as well as finding accommodation for people who have turned up in town with nothing. Major Dean Herring of the Salvation Army in Timaru has been helping evacuees find places to live as well as dealing with the huge piles of donated goods.

A huge fist representing 'quakes', that is wearing a boxing glove, thumps a man who represents 'CHCH' (Christchurch) 'WHUMP! WHUMP! WHUMP!' The man is knocked out. Context - Magnitude 6.0 and 5.5 earthquakes rocked Christchurch again at 1pm and 2.20pm on 13th June 2011. These quakes follow the first earthquake on September 4th 2010 and the second on February 22nd 2011. (www.stuff.co.nz, 13 June 2011) Quantity: 1 digital cartoon(s).

Text reads 'The earth takes... the world gives'. The cartoon shows an image of the globe with New Zealand in the centre - the continents seem to have formed themselves into a grieving face and arms which reach out to New Zealand. Context - on 22 February 2011 a 6.3 magnitude earthquake struck in Christchurch which has probably killed more than 200 people (at this point the number is still not known) and caused very severe damage.
