A video of the 2016 Civic Earthquake Memorial Service, held to mark the fifth anniversary of the 22 February 2011 earthquake. The service was held on the Archery Lawn in the Christchurch Botanic Gardens at midday on 22 February 2016. The service was filmed for the Christchurch City Council by Alan Radford of Multicam TV.

A video of a press conference with Anglican Bishop Victoria Matthews and Dean Peter Beck, about the interim plans for the earthquake-damaged ChristChurch Cathedral. In the press conference Matthews announces that the Cathedral will be deconsecrated, that parts of it will be demolished, and that the rest will be made safe. These measures will allow the recovery of artefacts and heritage items from the building.

The Mainland Touch was a popular regional news magazine programme broadcast from Christchurch between 1980 until 1990. In excerpts here, Christchurch Botanic Gardens welcomes the arrival of spring with a daffodil festival while local gardening groups prepare a floral carpet. The Wizard of Christchurch battles Telecom over the colour of phone boxes and joins opponents of a proposed restaurant tower in Victoria Square. Punting on the Avon is extended, and a cockatoo hitches a ride in the garden city.

Earthquakes cause significant damage to buildings due to strong vibration of the ground. Levitating houses using magnets and electromagnets would provide a complete isolation of ground motion for protecting buildings from seismic damage. Two types of initial configuration for the electromagnet system were proposed with the same air gap (10mm) between the electromagnet and reluctance plate. Both active and passive controller are modelled to investigate the feasibility of using a vibration control system for stabilizing the magnetic system within the designed air gap (10mm) in the vertical direction. A nonlinear model for the magnetic system is derived to implement numerical simulation of structural response under the earthquake record in Christchurch Botanic Gardens on 21 February 2011. The performance of the uncontrolled and the controlled systems are compared and the optimal combination of control gains are determined for the PID active controller. Simulation results show both active PID controller with constant and nonlinear attracting force are able to provide an effective displacement control within the required air gap (+/-5mm). The maximum control force demand for the PID controller in the presence of nonlinear attracting force is 4.1kN, while the attracting force in equilibrium position is 10kN provided by the electromagnet. These results show the feasibility of levitating a house using the current electromagnet and PID controller. Finally, initial results of passive control using two permanent magnets or dampers show the structural responses can be effectively reduced and centralized to +/-1mm using a nonlinear centring barrier function.
