This study compiled and tabulated all relevant available information on earthquake sources (active faults) in Canterbury and mapped the fault locations onto 1:50,000 or 1:250,000 overlays on topographic maps (later digitised into the Environment Canterbury active faults database). The study also reviewed information on historic earthquakes, instrumental seismicity and paleoseismic studies and identified information gaps. It recommended an approach for a probabilistic seismic hazard analysis and development of earthquake scenarios. See Object Overview for background and usage information.

Aerial footage of a site in Avondale where several liquefaction remediation options are being tested. Gelignite explosives have been buried throughout the site. These will be set off to simulate liquefaction caused by an earthquake. The result, if successful, will help EQC protect people's houses from future earthquakes, and settle land claims. The video was recorded using a drone aircraft.

A video of a presentation by Professor David Johnston during the fourth plenary of the 2016 People in Disasters Conference. Johnston is a Senior Scientist at GNS Science and Director of the Joint Centre for Disaster Research in the School of Psychology at Massey University. The presentation is titled, "Understanding Immediate Human Behaviour to the 2010-2011 Canterbury Earthquake Sequence, Implications for injury prevention and risk communication".The abstract for the presentation reads as follows: The 2010 and 2011 Canterbury earthquake sequences have given us a unique opportunity to better understand human behaviour during and immediately after an earthquake. On 4 September 2010, a magnitude 7.1 earthquake occurred near Darfield in the Canterbury region of New Zealand. There were no deaths, but several thousand people sustained injuries and sought medical assistance. Less than 6 months later, a magnitude 6.2 earthquake occurred under Christchurch City at 12:51 p.m. on 22 February 2011. A total of 182 people were killed in the first 24 hours and over 7,000 people injured overall. To reduce earthquake casualties in future events, it is important to understand how people behaved during and immediately after the shaking, and how their behaviour exposed them to risk of death or injury. Most previous studies have relied on an analysis of medical records and/or reflective interviews and questionnaire studies. In Canterbury we were able to combine a range of methods to explore earthquake shaking behaviours and the causes of injuries. In New Zealand, the Accident Compensation Corporation (a national health payment scheme run by the government) allowed researchers to access injury data from over 9,500 people from the Darfield (4 September 2010) and Christchurch (22 February 2011 ) earthquakes. The total injury burden was analysed for demography, context of injury, causes of injury, and injury type. From the injury data inferences into human behaviour were derived. We were able to classify the injury context as direct (immediate shaking of the primary earthquake or aftershocks causing unavoidable injuries), and secondary (cause of injury after shaking ceased). A second study examined people's immediate responses to earthquakes in Christchurch New Zealand and compared responses to the 2011 earthquake in Hitachi, Japan. A further study has developed a systematic process and coding scheme to analyse earthquake video footage of human behaviour during strong earthquake shaking. From these studies a number of recommendations for injury prevention and risk communication can be made. In general, improved building codes, strengthening buildings, and securing fittings will reduce future earthquake deaths and injuries. However, the high rate of injuries incurred from undertaking an inappropriate action (e.g. moving around) during or immediately after an earthquake suggests that further education is needed to promote appropriate actions during and after earthquakes. In New Zealand - as in US and worldwide - public education efforts such as the 'Shakeout' exercise are trying to address the behavioural aspects of injury prevention.

A PDF of an article written by Dr Lucy D'Aeth (CDHB) titled "All Right? The question that starts a conversation about wellbeing". D'Aeth discusses the All Right? campaign in the context of research into peoples wellbeing following the Canterbury earthquake. The article was intended as a 'Perspectives Piece' in April 2013.

A video of a presentation by Hugh Cowan, General Manager of Reinsurance, Research and Education at EQC, at the 2016 Seismics in the City Conference. The presentation is titled, "Working Together Strengthens Understanding".The abstract for the presentation reads, "Hear how EQC led a collaborative research project in Canterbury that involved diverse stakeholders from government, council officials and insurers to homeowners, and why collaboration means that Canterbury's geotechnical data is now helping to inform research locally, nationally and around the world."

A video of a keynote presentation by Dr Laurie Johnson, Project Scientist at the Pacific Earthquake Engineering Research Centre, at the 2016 Seismics in the City Conference. The presentation is titled, "The Trajectory of Post-disaster Recovery and Regeneration: Learning from other cities".The abstract for the presentation reads, "What does regeneration look like and how long does it take? A look at what we can learn about regeneration from other cities that have experienced disasters. An exploration of the innovation needed to fulfil the recovery vision, as well as the value of collaboration in the next five years."
