A photograph submitted by Raymond Morris to the QuakeStories website. The description reads, "The Provincial Hotel, corner Barbadoes and Cashel streets is one the buildings now missing after the 2011 earthquakes, paintings of others can be found on the artist Raymond Morris’s flickr site (http://www.flickr.com/photos/rayso180/sets/72157626939956494/)".

Asset management in power systems is exercised to improve network reliability to provide confidence and security for customers and asset owners. While there are well-established reliability metrics that are used to measure and manage business-as-usual disruptions, an increasing appreciation of the consequences of low-probability high-impact events means that resilience is increasingly being factored into asset management in order to provide robustness and redundancy to components and wider networks. This is particularly important for electricity systems, given that a range of other infrastructure lifelines depend upon their operation. The 2010-2011 Canterbury Earthquake Sequence provides valuable insights into electricity system criticality and resilience in the face of severe earthquake impacts. While above-ground assets are relatively easy to monitor and repair, underground assets such as cables emplaced across wide areas in the distribution network are difficult to monitor, identify faults on, and repair. This study has characterised in detail the impacts to buried electricity cables in Christchurch resulting from seismically-induced ground deformation caused primarily by liquefaction and lateral spread. Primary modes of failure include cable bending, stretching, insulation damage, joint braking and, being pulled off other equipment such as substation connections. Performance and repair data have been compiled into a detailed geospatial database, which in combination with spatial models of peak ground acceleration, peak ground velocity and ground deformation, will be used to establish rigorous relationships between seismicity and performance. These metrics will be used to inform asset owners of network performance in future earthquakes, further assess component criticality, and provide resilience metrics.

A photograph submitted by Raymond Morris to the QuakeStories website. The description reads, "Cathedral of the Blessed Sacrament, Barbadoes Street. The Cathedral was opened in 1905, the architect was Frank Petrie, and was designed in the Italian renaissance style as a basilica. It is not certain yet whether it will be reconstructed after the 2011 earthquakes.".

People gather beside the Avon River in Riccarton Bush for the River of Flowers event, commemorating the second anniversary of the 22 February earthquake. A sign reads "In memory of those we lost, Feb 22nd 2011, River of Flowers". One of the organisers holds a basket of flowers, to distribute to people who couldn't bring their own.

A photograph of the Townsend Telescope. The telescope is in the Observatory at the Christchurch Arts Centre. A plate on the side reads, "T Cook & Sons, 1864, York & London". This image was used by Graeme Kershaw, Technician at the University of Canterbury Department of Physics and Astronomy, to identify the telescope's parts after the 22 February 2011 earthquake.
