This study provides an initial examination of source parameter uncertainty in a New Zealand ground motion simulation model, by simulating multiple event realisations with perturbed source parameters. Small magnitude events in Canterbury have been selected for this study due to the small number of source input parameters, the wealth of recorded data, and the lack of appreciable off-fault non-linear effects. Which provides greater opportunity to identify systematic source, path and site effects, required to robustly investigate the causes of uncertainty.

Donations to the Canterbury earthquake fund now total about $11 million. It comes as the Government announced early details of a recovery plan for people wanting money to fix their damaged homes or start rebuilding.

Allison, one of the heart stitchers outside the library. The felt hearts were a healing outlet during the Canterbury earthquakes. The goal was to create beauty in the midst of chaos, to keep people's hands busy and their minds off the terrifying reality of the earthquakes, as well as to give a gift of love to workers and businesses who helped improve life in Lyttelton.

A woman badly injured in the Christchurch earthquake is astonished a new building in the city has been found to have serious seismic flaws. The empty new office building at 230 High Street has multiple problems in its earthquake design that the city council was warned about almost two years ago. Construction of the seven-storey building continued even after those warnings in December 2017. Susie Ferguson speaks to University of Canterbury lecturer Ann Brower, who was crushed after falling masonry fell on her bus during the February twenty-second 2011 earthquake.

A Christchurch earthquake insurance specialist says a critical report of the Earthquake Commission is a good start but doesn't go far enough. The report by an independent ministerial advisor says EQC staff have no confidence in their own data, and that the organisation needs to dramatically improve the way it communicates with claimants. The advisor, Christine Stevenson, said EQC was unable even to tell her how many claims it's still dealing with from the Canterbury earthquakes. Dean Lester is a Christchurch insurance advocate and claims preparer. He talks to Susie Ferguson.

Yes, it was a joke. The tours, that is, not the yard filled with earthquake-caused sand volcanos. They were very real. You can see one covering the driveway in this photo. The signs read as follows. "Tours run 1/2 hourly. $5.25 admission. Eftpos unavailable." "If you think this is bad... you should see the back!"

A shaken All Blacks supporter stands under the title 'Shamrocked!!. Around him is a news report of a recent 3 point magnitude earthquake in Christchurch, and surrounding him are the familiar earthquake terms 'Very Shakey', 'faultines' 'shocks' and 'cracks appearing'. On 16 June 2012, the Irish rugby team ('The Shamrocks' ) almost beat the All Blacks in Christchurch. The All Black team performance was poor, especially after their first win a week before. Co-incidentally, another earthquake had hit Christchurch. New Zealand fans were shaken by both events. Quantity: 1 digital cartoon(s).

Shows a man exhausted after a weekend of watching the All Blacks playing Ireland on TV. His wife understands the frustration of Christchurch residents waiting too long for repairs to properties. Context: Refers to frustrating delays in getting earthquake-related repairs done in Christchurch, this in large part due to slowness of insurance claims and permissions.

The sequence of earthquakes that has greatly affected Christchurch and Canterbury since September 2010 has again demonstrated the need for seismic retrofit of heritage unreinforced masonry buildings. Commencing in April 2011, the damage to unreinforced stone masonry buildings in Christchurch was assessed and recorded with the primary objective being to document the seismic performance of these structures, recognising that they constitute an important component of New Zealand’s heritage architecture. A damage statistics database was compiled by combining the results of safety evaluation placarding and post-earthquake inspections, and it was determined that the damage observed was consistent with observations previously made on the seismic performance of stone masonry structures in large earthquakes. Details are also given on typical building characteristics and on failure modes observed. Suggestions on appropriate seismic retrofit and remediation techniques are presented, in relation also to strengthening interventions that are typical for similar unreinforced stone masonry structures in Europe.

Live monitoring data and simple dynamic reduced-order models of the Christchurch Women’s Hospital (CWH) help explain the performance of the base isolation (BI) system of the hospital during the series of Canterbury earthquakes in 2011-2012. A Park-Wen-Ang hysteresis model is employed to simulate the performance of the BI system and results are compared to measured data recorded above the isolation layer and on the 6th story. Simplified single, two and three degree of freedom models (SDOF, 2DOF and 3DOF) show that the CWH structure did not behave as an isolated but as a fixed-base structure. Comparisons of accelerations and deflections between simulated and monitored data show a good match for isolation stiffness values of approximately two times of the value documented in the design specification and test protocol. Furthermore, an analysis of purely measured data revealed very little to no relative motion across the isolators for large events of moment magnitude scale (Mw) 5.8 and 6.0 that occurred within 3 hours of each other on December 23, 2011. One of the major findings is that the BI system during the seismic events on December 23, 2011 did not yield and that the superstructure performed as a fixed-base building, indicating a need to reevaluate the analysis, design and implementation of these structures.
