I think all the National Banks in the country have been either closed or rebranded ANZ, but this one on the corner of Colombo and Armagh Streets is still inside the CBD red zone and has yet to be touched. I have heard that this building is staying so whether it becomes an ANZ or not time will tell. This was one of the top five busiest pedest...

20130704_7677_EOS M-22 Another one on the way out (Day 185/365) A suburban "red zone" house from Velsheda Street (#11), Pacific Park, is finally cut in half and loaded ready for transport out and a future life somewhere else in the South Island, whether it be close by or way down south in Gore or Clinton (where a few have gone already). The hou...

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.

Went for a drive down to South New Brighton/Southshore after work today to see what interesting birds I could find on the Estuary (godwits, skuas, terns etc), but passing Jellico Street, I saw this. T-Rex the seismic survey truck from the University of Texas that is visiting the city (first time out of USA). Weighs 30 tonne and from the marks o...

Awaiting the demolition ball! See the hole punched in by the neighbouring building (now demolished) during the February 22 2011 earthquake. This building is leaning to the north (left) while it's now demolished neighbour was leaning to the south (right). All because the crap land gave way underneath!

20130808_2300_1D3-40 Warning (Day 220/365) Across the river were a row of several houses - all gone now. That side of the river is "Red Zone" and will be devoid of houses soon. #4077

20130325_1112_EOS M-25 Water water everywhere! (Day 84/365) While the whole of the North Island is under drought conditions and parts of the South Island likely to follow suit, I doubt it will happen in Christchurch. With hundreds of earthquake road, water and sewer repairs underway many are spilling hundreds of litres of water per minute, like...

20100918_3497_1D3-24 Porritt Park - Christchurch earthquake The Avon River loop around Porritt Park has risen with the quake. Huge cracks are all through Porritt Park (rowing, hockey and cricket venue). The main section of the river is in a man made cut behind the buildings in the background of this pic. #401

Only two of 20 houses left in the Rawhiti Earthquake Village. This from the sign on perimeter fence: "Since 2011, Rawhiti Domain has been used to provide temporary accommodation for those affected by the Canterbury earthquakes. Over 200 households have used the 20 houses while their own homes have been repaired or rebuilt. The demand for acco...

Surface-rupturing earthquakes can trigger the sudden avulsion of river channels, causing rapid and persistent coseismic flooding of previously unaffected areas. This phenomenon, known as fault-rupture-induced river avulsion (FIRA), occurs when fault displacement significantly alters river channel topography. The importance of understanding FIRA as a secondary seismic hazard was highlighted by events during the 2010 Darfield and 2016 Kaikoura earthquakes in New Zealand. This thesis develops a national model to identify and quantify FIRA susceptibility across New Zealand by integrating hydrological datasets (NIWA RiverMaps and Flood Statistics) with active fault information (NZ Active Faults Database and RSQSim earthquake simulations). The methodology applies the F-index framework proposed by McEwan et al. (2023), which quantifies FIRA potential based on the ratio of fault throw plus discharge-dependent depth to bank full depth at each fault-river intersection. The model successfully identified 3,796 potential FIRA-susceptible fault-river intersections nationwide, with 451 involving waterways equal to or larger than the Hororata River. Regional analysis revealed higher concentrations of FIRA-susceptible sites in the Bay of Plenty, Canterbury, and Marlborough regions. Validation against historical events showed the model effectively located known FIRA occurrences from the Kaikoura and Darfield earthquakes, though with some limitations in accurately predicting F-index values due to complex fault displacement patterns and challenges in modelling bank full depths of large, braided rivers. This research establishes New Zealand's first nationwide assessment of fault-induced river avulsion susceptibility. The approach creates a structured methodology for identifying high-risk fault-river intersections and determining which sites require thorough localised examination. The methodology developed offers a template for similar assessments in other tectonically active regions and contributes to improving earthquake hazard assessment and disaster preparedness planning.

In 2010 and 2011 a series of earthquakes hit the central region of Canterbury, New Zealand, triggering widespread and damaging liquefaction in the area of Christchurch. Liquefaction occurred in natural clean sand deposits, but also in silty (fines-containing) sand deposits of fluvial origin. Comprehensive research efforts have been subsequently undertaken to identify key factors that influenced liquefaction triggering and severity of its manifestation. This research aims at evaluating the effects of fines content, fabric and layered structure on the cyclic undrained response of silty soils from Christchurch using Direct Simple Shear (DSS) tests. This poster outlines preliminary calibration and verification DSS tests performed on a clean sand to ensure reliability of testing procedures before these are applied to Christchurch soils.
