A magnitude 6.3 earthquake struck the city of Christchurch at 12:51pm on Tuesday 22 February 2011. The earthquake caused 182 fatalities, a large number of injuries, and resulted in widespread damage to the built environment, including significant disruption to the lifelines. The event created the largest lifeline disruption in a New Zealand city in 80 years, with much of the damage resulting from extensive and severe liquefaction in the Christchurch urban area. The Christchurch earthquake occurred when the Canterbury region and its lifelines systems were at the early stage of recovering from the 4 September 2010 Darfield (Canterbury) magnitude 7.1 earthquake. This paper describes the impact of the Christchurch earthquake on lifelines by briefly summarising the physical damage to the networks, the system performance and the operational response during the emergency management and the recovery phase. Special focus is given to the performance and management of the gas, electric and road networks and to the liquefaction ejecta clean-up operations that contributed to the rapid reinstatement of the functionality of many of the lifelines. The water and wastewater system performances are also summarized. Elements of resilience that contributed to good network performance or to efficient emergency and recovery management are highlighted in the paper.

A video of an interview with Bruce Greenhalgh about the experiences of Smiths Sports Shoes after the 2010 and 2011 earthquakes. The business had to move from Moorhouse Avenue after the 4 September 2010 earthquake to Montreal Street. The 22 February 2011 earthquake then damaged their building on Montreal Street, forcing them to move again.

A video about the experiences of church goers after the 4 September 2010 earthquake. Many of the congregations have had to find temporary facilities after the earthquake damaged their churches. The video includes an interview with Bishop Barry Jones from the Roman Catholic Church. Jones talks about the miracle that nobody died in the earthquake.
