A video about the contrasting experiences of business owners in Beckenham after the 4 September 2010 earthquake. The video includes an interview with Fred Arnesen, owner of Beckenham Footware & Engravers, and Fiona Fidow and Jeanie Smith, owners of The Cupcake Collection. The stores are on opposite sides of Colombo Street, with the west side suffering severe damage, and the east side suffering very little. Because of this, the Beckenham Footware & Engravers has had to close, while The Cupcake Collection is able to continue operating.

This report describes the earthquake hazard in Waimate and Mackenzie districts and the part of Waitaki district within Canterbury, and gives details of historic earthquakes. It includes district-scale (1:500,000) active fault, ground shaking zone, liquefaction and landslide susceptibility maps. The report describes earthquake scenarios for a magnitude 7.2-7.4 Ostler Fault earthquake near Twizel, a magnitude 8 Alpine Fault earthquake, and a magnitude 6.9 Hunters Hills Fault Zone earthquake near Waimate. See Object Overview for background and usage information.

In three small frames above the main frame, milk tankers are shown bumping wildly over Christchurch roads made uneven by the earthquakes of September 4 2010 and February 22 2011; and in the large frame below a man is painting out the word 'milk' on a tanker and replacing it with the word 'butter'. Context - the bad roads caused by the erathquakes in Canterbury have turned the milk into butter. Colour and black and white versions available Title from file name Quantity: 2 digital cartoon(s).

Shows the face of a man with a large tear rolling down his cheek ; in the tear is the word 'Christchurch'. Context - On 22 February 2011 at 12:51 pm (NZDT), Christchurch experienced a major magnitude 6.3 earthquake, which resulted in severe damage and many casualties. A National State of Emergency has been declared. This followed on from an original magnitude 7.1 earthquake on 4 September 2010 which did far less damage and in which no-one died. Quantity: 1 digital cartoon(s).

A woman sits reading a newspaper with reports about the Japanese earthquake and the latest news on Christchurch post-earthquake. Her husband has just put a Jerry Lee Lewis record on the turntable and the song 'Whole lotta shakin' goin' on' is playing; he says Didn't I always say this guy was ahead of his time?' Context - The Christchurch earthquakes of September 4 2010 and February 22 2011 as well as the Japanese earthquake and tsunami of 11 March 2011. Quantity: 1 digital cartoon(s).

The Stone Jug Fault (SJF) ruptured during the November 14th, 2016 (at 12:02 am), Mw 7.8 Kaikōura Earthquake which initiated ~40 km west-southwest of the study area, at a depth of approximately 15 km. Preliminary post-earthquake mapping indicated that the SJF connects the Conway-Charwell and Hundalee faults, which form continuous surface rupture, however, detailed study of the SJF had not been undertaken prior to this thesis due to its remote location and mountainous topography. The SJF is 19 km long, has an average strike of ~160° and generally carries approximately equal components of sinistral and reverse displacement. The primary fault trace is sigmoidal in shape with the northern and southern tips rotating in strike from NNW to NW, as the SJF approaches the Hope and Hundalee faults. It comprises several steps and bends and is associated with many (N=48) secondary faults, which are commonly near irregularities in the main fault geometry and in a distributed fault zone at the southern tip. The SJF is generally parallel to Torlesse basement bedding where it may utilise pre-existing zones of weakness. Horizontal, vertical and net displacements range up to 1.4 m, with displacement profiles along the primary trace showing two main maxima separated by a minima towards the middle and ends of the fault. Average net displacement along the primary trace is ~0.4m, with local changes in relative values of horizontal and vertical displacement at least partly controlled by fault strike. Two trenches excavated across the northern segment of the fault revealed displacement of mainly Holocene stratigraphy dated using radiocarbon (N=2) and OSL (N=4) samples. Five surface-rupturing paleoearthquakes displaying vertical displacements of <1 m occurred at: 11,000±1000, 7500±1000, 6500±1000, 3500±100 and 3 (2016 Kaikōura) years BP. These events produce an average slip rate since ~11 ka of 0.2-0.4 mm/yr and recurrence intervals of up to 5500 years with an average recurrence interval of 2750 yrs. Comparison of these results with unpublished trench data suggests that synchronous rupture of the Hundalee, Stone Jug, Conway-Charwell, and Humps faults at ~3500 yrs BP cannot be discounted and it is possible that multi-fault ruptures in north Canterbury are more common than previously thought.

This thesis is concerned with springs that appeared in the Hillsborough, Christchurch during the 2010-2011 Canterbury Earthquake Sequence, and which have continued to discharge groundwater to the surface to the present time. Investigations have evolved, measurements of discharge at selected sites, limited chemical data on anions and isotope analysis. The springs are associated with earthquake generated fissures (extensional) and compression zones, mostly in loess-colluvium soils of the valley floor and lower slopes. Extensive peat swamps are present in the Hillsborough valley, with a groundwater table at ~1m below ground. The first appearance of the ‘new’ springs took place following the Mw 7.1 Darfield Earthquake on 4 September 2010, and discharges increased both in volume and extent of the Christchurch Mw 6.3 Earthquake of 22 February 2011. Five monitored sites show flow rates in the range of 4.2-14.4L/min, which have remained effectively constant for the duration of the study (2014-2015). Water chemistry analysis shows that the groundwater discharges are sourced primarily from volcanic bedrocks which underlies the valley at depths ≤50m below ground level. Isotope values confirm similarities with bedrock-sourced groundwater, and the short term (hours-days) influence of extreme rainfall events. Cyclone Lusi (2013-2014) affects were monitored and showed recovery of the bedrock derived water signature within 72 hours. Close to the mouth of the valley sediments interfinger with Waimakiriri River derived alluvium bearing a distinct and different isotope signature. Some mixing is evident at certain locations, but it is not clear if there is any influence from the Huntsbury reservoir which failed in the Port Hills Earthquake (22 February 2011) and stored groundwater from the Christchurch artesian aquifer system (Riccarton Gravel).

The Christchurch earthquake sequence has been on-going since September 4th 2010. The largest two earthquakes, magnitude (M) 7.1 on September 4th and the M 6.3 on February 22nd 2011 caused immediate and significant damage to the city of Christchurch. As a consequence of the earthquakes, the tourism sector in the Canterbury region has been heavily impacted, with broader impacts being felt throughout the South Island. Resilient Organisations and the University of Canterbury began a series of quantitative investigations into the recovery and response of key business sectors to the earthquakes. The purpose of this study was to build on this work by exploring the outcomes of the earthquakes on the tourism sector, a critical economic driver in the region. Two postal surveys were sent to 719 tourism business managers; the first to businesses in the ‘Impact Zone’ defined as areas that experienced Modified Mercalli intensities greater than 6. The second survey was sent to the remaining businesses throughout the Canterbury region (‘Rest of Canterbury’). Response rates were 46% response for the Impact Zone, and 29% for the Rest of Canterbury. Key findings:

Context - Christchurch earthquake of 22 February 2011 and the start of debate about how city should be rebuilt. The historic man suggests a strong pull to preserve historic Christchurch.

'Cappuccino dreams'. Christchurch mayoral candidates Jim Anderton and incumbent mayor Bob Parker tell constituents that they will get respectively more transparency in 'financial dealings' and in 't-shirts'. As the earthquake strikes they continue their electioneering until they are told to 'clear orf' because 'these frames lack substance'. A front-end loader begins to dismantle the structure from which they are speaking. Refers to the local body elections to take place 9th October and the Canterbury earthquake of 4th September.
