Damage to Medway Street in Richmond. The road surface is cracked and buckled, and covered in liquefaction silt. A temporary road sign restricting speed to 30 is visible, with road cones behind. The photographer comments, "Medway St, Woodchester Ave on right just beyond the 30 sign".
A photograph of earthquake-damaged buildings along Manchester Street near Struthers Lane. The front of the buildings have crumbled, the bricks falling onto the footpath in front, damaging the awnings.

Internal damage to a house in Richmond. A crack in a windowsill where the sill has separated from the window frame. The photographer comments, "Window frame in dining nook".
Damage to a house in Richmond. Part of a brick wall has slumped, leaving a large gap between the wall and a window frame. The photographer comments, "Sunroom window frame".
Damage to a house in Richmond. A brick chimney has partially collapsed. The photographer comments, "The chimney above our bedroom crumbled - glad it didn't come down in one piece".
Damage to a house in Richmond. There is a large crack in the driveway, and cracks in the brickwork of a house. The photographer comments, "Tarsealed driveways have numerous cracks".

Utility managers are always looking for appropriate tools to estimate seismic damage in wastewater networks located in earthquake prone areas. Fragility curves, as an appropriate tool, are recommended for seismic vulnerability analysis of buried pipelines, including pressurised and unpressurised networks. Fragility curves are developed in pressurised networks mainly for water networks. Fragility curves are also recommended for seismic analysis in unpressurised networks. Applying fragility curves in unpressurised networks affects accuracy of seismic damage estimation. This study shows limitations of these curves in unpressurised networks. Multiple case study analysis was applied to demonstrate the limitations of the application of fragility curves in unpressurised networks in New Zealand. Four wastewater networks within New Zealand were selected as case studies and various fragility curves used for seismic damage estimation. Observed damage in unpressurised networks after the 2007 earthquake in Gisborne and the 2010 earthquake in Christchurch demonstrate the appropriateness of the applied fragility curves to New Zealand wastewater networks. This study shows that the application of fragility curves, which are developed from pressurised networks, cannot be accurately used for seismic damage assessment in unpressurised wastewater networks. This study demonstrated the effects of different parameters on seismic damage vulnerability of unpressurised networks.
A photograph of the earthquake damage to a building on the corner of Gloucester and Manchester Streets. Sections of the façade have crumbled, the bricks spilling onto the footpath below. Wire fencing has been placed around the building as a cordon. In the distance there are many other earthquake-damaged buildings.
