Road damage and liquefaction in a residential street. The photographer comments, "A great gouge in the road caused by liquefaction undermining the road surface and a car driving over it. This was the earthquake in Christchurch, New Zealand on 22 February 2011".

The title reads 'Ellerslie Flower Show to return to Christchurch...' Below are nine cameos showing 'sinking violets', 'cracked chrysanthemums', 'pooey perrenials', 'rubble roses', 'portaloo poppies', 'munted marigolds', 'knackered natives', the 'lily of liquefaction' and 'wearable exhibits' which shows a woman wearing a toilet roll and carrying a spade. Context: The next Ellerslie International Flower Show will be staged in North Hagley Park from 7-11 March 2012. Following cancellation of the 2011 Show after the 22 February earthquake, Christchurch City Council has confirmed that the citys premier garden show will go ahead next year in the same venue as previous years.

ACT leader Rodney Hide stands alone in the middle of a blasted plain that was once the 'Christchurch CBD' and says 'A level playing field, excellent. Now we can leave the rest to the market'. Context - Christchurch after the earthquakes of 4 September 2010 and 22 February 2011. ACT explicitly promotes a free market philosophy - a (literal) level playing field in the Christchurch CBD sounds like an excellent opportunity to test the powers of the free market.

Deborah Nation recalls how it was in the Sound Archives and Radio New Zealand offices in Christchurch on the day of the February earthquake. The building on the corner of Durham and Chester Street West has been condemned. Please be aware that the first sounds of this report may be upsetting, especially to listenners who experienced the earthquake.

This manuscript provides a critical examination of the ground motions recorded in the near-source region resulting from the 22 February 2011 Christchurch earthquake. Particular attention is given to reconciling the observed spatial distribution of ground motions in terms of physical phenomena related to source, path and site effects. The large number of near-source observed strong ground motions show clear evidence of: forward-directivity, basin generated surface waves, liquefaction and other significant nonlinear site response. The pseudo-acceleration response spectra (SA) amplitudes and significant duration of strong motions agree well with empirical prediction models, except at long vibration periods where the influence of basin-generated surface waves and nonlinear site response are significant and not adequately accounted for in empirical SA models. Pseudo-acceleration response spectra are also compared with those observed in the 4 September 2010 Darfield earthquake and routine design response spectra used in order to emphasise the amplitude of ground shaking and elucidate the importance of local geotechnical characteristics on surface ground motions. The characteristics of the observed vertical component accelerations are shown to be strongly dependent on source-to-site distance and are comparable with those from the 4 September 2010 Darfield earthquake, implying the large amplitudes observed are simply a result of many observations at close distances rather than a peculiar source effect.
