Another city walk around, this time with my brother-in-law from Auckland. Also went to the Quake City exhibition in the city organised by the Canterbury Museum. First fine day for a while. This bus is used as a chocolate restaurant, and is parked next to the Pallet Pavilion on the site of the old Park Royal Hotel.

A large group of people stand on a huge sundial in a pattern that forms a map of New Zealand; the hand of the sundial casts a shadow that falls on nine minutes to one. Context - the people of New Zealand maintained a vigil of two minutes silence at 12.51 on 1 March which was exactly a week after the Christchurch earthquake of 22 February struck.

Christmas is getting closer!!' Context; the Christchurch earthquake on 4th September and all the subsequent aftershocks have cost many people a great deal of money. Quantity: 1 digital cartoon(s).

Today was the first time I have been to the earthquake memorial since it was completed and opened on 22nd February 2017, six years after the devastating quake that killed the 185 that are named on this wall. I knew two of the people on the list.

Question: Does canopy tree regeneration response to different large disturbances vary with soil drainage? Location: Old-growth conifer (Dacrydium and Dacrycarpus), angiosperm (Nothofagus and Weinmannia) rain forest, Mount Harata, South Island, New Zealand. Methods: Trees were aged (1056 cores) to reconstruct stand history in 20 (0.12 - 0.2 ha) plots with different underlying drainage. Spatial analyses of an additional 805 tree ages collected from two (0.3 - 0.7 ha) plots were conducted to detect patchiness for five canopy tree species. Microsite preferences for trees and saplings were determined. Results: There were clear differences in species regeneration patterns on soils with different drainage. Conifer recruitment occurred infrequently in even-aged patches (> 1000 m²) and only on poorly drained soils. Periodic Nothofagus fusca and N. menziesii recruitment occurred more frequently in different sized canopy openings on all soils. Weinmannia recruitment was more continuous on all soils reflecting their greater relative shade-tolerance. Distinct periods of recruitment that occurred in the last 400 years matched known large disturbances in the region. These events affected species differently as soil drainage varied. Following earthquakes, both conifers and N. menziesii regenerated on poorly drained soils, while Nothofagus species and Weinmannia regenerated on well-drained soils. However, Dacrydium failed to regenerate after patchy storm damage in the wetter forest interior; instead faster-growing N. fusca captured elevated microsites caused by uprooting. Conclusions: Underlying drainage influenced species composition, while variation in the impacts of large disturbance regulated relative species abundances on different soils.

Text reads 'Solution to Christchurch sewage problems?...' A woman, with a roll of toilet paper in her hand, climbs a ladder to a toilet that is positioned on a sewage pipe high above the ground. There are further toilets at intervals on the pipe. Her husband stands in the garden and observes that it is 'Easy to access and easy to repair'. Context - the Christchurch earthquakes and continuing aftershocks have done huge damage to sewage infrastructures which suggests having the pipes above ground as a solution.

The small crane on the back of a rubbish truck has picked up a whole portaloo and dumped its contents (a man with his pants around his ankles) into the rubbish. The driver tells the crane operator that he should have emptied 'the bin! ... Not the portaloo!'. A streetsign reads 'Avonside'. Refers to the use of portaloos in parts of Christchurch since the earthquake of 4th September because of damage to plumbing infrastructure. Quantity: 1 digital cartoon(s).

The Christchurch Cathedral Square showing the Anglican Cathedral after loosing its tower and spire after the 6.3 quake hit Christchurch 22 February 2011. This image also shows the remains of the very heavy snow fall we had on Monday 25 July 2011. The centre of the city is still cordoned off. This image was taken from a helicopter flight over the...

Minister for Christchurch Recovery, Gerry Brownlee drives a huge tractor among debris that spells out 'Due Process' and says 'In order to get Christchurch back on its feet again we have to bring parliament to its knees. Context - The minister says he is happy with the speed of the work being done, as he wants tomake sure those involved in the rebuild portion of the recovery effort are well prepared. The bill establishes the Canterbury Earthquake Recovery Authority (Cera) and empowers it to lead reconstruction efforts in Christchurch. It gives Cera specific powers to get information from any source, to requisition and build on land and to carry out demolitions. It can also take over local authorities if they are not working effectively on recovery work. 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.
