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 policeman and his dog stop outside a house wrecked in the Christchurch earthquake and phone for assistance saying 'Have found signs of low-life' because he can see 'Christchurch looting in progress'. Context - on 22 February 2011 a 6.3 magnitude earthquake struck in Christchurch, which has probably killed more than 200 people (at this point the number is still not known) and caused very severe damage. The courage, generosity and 'can do' attitude of the people has been wonderful apart from the antisocial behaviour of a few looters and others taking advantage of the situation.

A small boy is being a real entrepreneur after the Christchurch earthquake of 22 February 2011 and has set up a road-side stall from which you can buy a bag of 'real leakyfakshun'. Behind him is a pile of liquefaction and a spade with which he can fill bags. Context - the Christchurch earthquake of 22 February has caused vastly more liquefaction than the original 4th September earthquake. The vibrations from the quake cause liquefaction which is where the soil loses strength and stiffness, and behaves more like a liquid than a solid - rather like wet sand. Colour and black and white versions available Quantity: 2 digital cartoon(s).

Someone holds a mobile phone and sends a text 'CH CH WE R ALL IN THS 2 GTHR' (Christchurch we are all in this together). Context - On 22 February 2011 at 12:51 pm (NZDT), Christchurch experienced a major magnitude 6.3 earthquake, which resulted in severe damage and many casualties. A National State of Emergency has been declared. This followed on from an original magnitude 7.1 earthquake on 4 September 2010 which did far less damage and in which no-one died. Both colour and black and white versions of this cartoon are available Quantity: 2 digital cartoon(s).

Text across the top of the cartoon reads 'The reminder again' and shows a disaster kit in a box labeled 'Your B-Ready Disaster Kit'. Nearby are newspapers recording the text 'no power', 'shortage of blankets', 'boil water'. Context - a warning for everyone to prepare disaster kits brought home by the Christchurch earthquake of 22 February 2011. On 22 February 2011 at 12:51 pm (NZDT), Christchurch experienced a major magnitude 6.3 earthquake, which resulted in severe damage and many casualties. A National State of Emergency has been declared. This followed on from an original magnitude 7.1 earthquake on 4 September 2010 which did far less damage and in which no-one died.
