A time-lapse video of several locations in the Christchurch central city. The locations include the intersection of Gloucester and Manchester Streets, the intersection of Colombo and Armagh Streets, the ChristChurch Cathedral, Cashel Street, and the intersection of Lichfield and Manchester Streets.

A sign outside the Chinwag Eathai restaurant on Victoria Street reads "To all our valued customers. We are sorry to inform you as of Tuesday 17th January 2012 our building has been red stickered. Don't worry we will be back at a new location!! Yet to be confirmed".

Highlights from Radio New Zealand National's programmes for the week ending Friday 7 December. This week ...... not everyone was keen on The Hobbit world premiere party, measuring and assessing innovation, expecting excellence of all students in education no matter what race they are, a world wide gathering of "Dobson's" tour ancestral South Island locations, The Christchurch Fiasco - what is going on with insurance companies post earthquakes, getting touchy feely with art and reggae star Jimmy Cliff on his spiritual life and learnings

The Darfield earthquake caused widespread damage in the Canterbury region of New Zealand, with the majority of damage resulting from liquefaction and lateral spreading. One of the worst hit locations was the small town of Kaiapoi north of Christchurch, an area that has experienced liquefaction during past events and has been identified as highly susceptible to liquefaction. The low lying town sits on the banks of the Kaiapoi River, once a branch of the Waimakariri, a large braided river transporting gravelly sediment. The Waimakariri has been extensively modified both by natural and human processes, consequently many areas in and around the town were once former river channels.

The Mw 7.1 Darfield earthquake generated a ~30 km long surface rupture on the Greendale Fault and significant surface deformation related to related blind faults on a previously unrecognized fault system beneath the Canterbury Plains. This earthquake provided the opportunity for research into the patterns and mechanisms of co-seismic and post-seismic crustal deformation. In this thesis I use multiple across-fault EDM surveys, logic trees, surface investigations and deformation feature mapping, seismic reflection surveying, and survey mark (cadastral) re-occupation using GPS to quantify surface displacements at a variety of temporal and spatial scales. My field mapping investigations identified shaking and crustal displacement-induced surface deformation features south and southwest of Christchurch and in the vicinity of the projected surface traces of the Hororata Blind and Charing Cross Faults. The data are consistent with the high peak ground accelerations and broad surface warping due to underlying reverse faulting on the Hororata Blind Fault and Charing Cross Fault. I measured varying amounts of post-seismic displacement at four of five locations that crossed the Greendale Fault. None of the data showed evidence for localized dextral creep on the Greendale Fault surface trace, consistent with other studies showing only minimal regional post-seismic deformation. Instead, the post-seismic deformation field suggests an apparent westward translation of northern parts of the across-fault surveys relative to the southern parts of the surveys that I attribute to post-mainshock creep on blind thrusts and/or other unidentified structures. The seismic surveys identified a deformation zone in the gravels that we attribute to the Hororata Blind Fault but the Charing Cross fault was not able to be identified on the survey. Cadastral re-surveys indicate a deformation field consistent with previously published geodetic data. We use this deformation with regional strain rates to estimate earthquake recurrence intervals of ~7000 to > 14,000 yrs on the Hororata Blind and Charing Cross Faults.

Photographs of central Christchurch after the 2010-2012 earthquakes taken 25 February 2012 by Sean McMahon. Locations are chiefly Manchester, Saint Asaph, Cashel, Columbo and Lichfield Streets, and the Bridge of Remembrance. Images show fencing around areas closed to the public, damaged and collapsed commercial buildings, cleared sites, re-opened Cashel Street area with shops and a cafe.
