The footpath on Williams Street bridge in Kaiapoi. Since the earthquake, it has been re-instated after new pipes were laid.

Damage to the pavement along the Williams Street bridge in Kaiapoi. Wire fencing with tape and road cones have been placed along the bridge to keep people away.

Cracks in a footpath in Kaiapoi, where the land has slumped towards the river.
An area next to the river in Kaiapoi where workers previously dug trenches to fix the power and communication lines. They have now been fixed and the trenches have been filled in. A pile of dirt can still be seen.
The banks of the Kaiapoi River have slumped towards the river, leaving a gap between the riverside walkway and the steps up to Raven Quay.
Construction teams are working to fix earthquake damaged stopbanks in the Waimakariri and Kaiapoi rivers near Christchurch.

Large cracks between concrete slabs in a pathway beside the Southern Region Coastguard Waimakariri-Ashley boathouse on Charles Street in Kaiapoi show how the land has slumped towards the river.
The Canterbury Civil Defence Duty Manager, James Thompson, says the Waimakariri River could breach its banks just south of Kaiapoi, and as a preacaution they have evacuated the Riverlands Holiday Park.
This is the pedestrian bridge in Kaiapoi close to Christchurch. Not the best angle but the whole bridge on the right hand side is twisted and looks like some kind of rollercoaster. Taken one month after the Quake Twitter |

The once level stop bank has lowered about 1.5 metres in place. Kaiapoi township is to the left of the frame".
On 4 September 2010, a magnitude Mw 7.1 earthquake struck the Canterbury region on the South Island of New Zealand. The epicentre of the earthquake was located in the Darfield area about 40 km west of the city of Christchurch. Extensive damage was inflicted to lifelines and residential houses due to widespread liquefaction and lateral spreading in areas close to major streams, rivers and wetlands throughout Christchurch and Kaiapoi. Unreinforced masonry buildings also suffered extensive damage throughout the region. Despite the severe damage to infrastructure and residential houses, fortunately, no deaths occurred and only two injuries were reported in this earthquake. From an engineering viewpoint, one may argue that the most significant aspects of the 2010 Darfield Earthquake were geotechnical in nature, with liquefaction and lateral spreading being the principal culprits for the inflicted damage. Following the earthquake, an intensive geotechnical reconnaissance was conducted to capture evidence and perishable data from this event. This paper summarizes the observations and preliminary findings from this early reconnaissance work.
On 4 September 2010, a magnitude Mw 7.1 earthquake struck the Canterbury region on the South Island of New Zealand. The epicentre of the earthquake was located in the Darfield area about 40 km west of the city of Christchurch. Extensive damage occurred to unreinforced masonry buildings throughout the region during the mainshock and subsequent large aftershocks. Particularly extensive damage was inflicted to lifelines and residential houses due to widespread liquefaction and lateral spreading in areas close to major streams, rivers and wetlands throughout Christchurch and Kaiapoi. Despite the severe damage to infrastructure and residential houses, fortunately, no deaths occurred and only two injuries were reported in this earthquake. From an engineering viewpoint, one may argue that the most significant aspects of the 2010 Darfield Earthquake were geotechnical in nature, with liquefaction and lateral spreading being the principal culprits for the inflicted damage. Following the earthquake, a geotechnical reconnaissance was conducted over a period of six days (10–15 September 2010) by a team of geotechnical/earthquake engineers and geologists from New Zealand and USA (GEER team: Geo-engineering Extreme Event Reconnaissance). JGS (Japanese Geotechnical Society) members from Japan also participated in the reconnaissance team from 13 to 15 September 2010. The NZ, GEER and JGS members worked as one team and shared resources, information and logistics in order to conduct thorough and most efficient reconnaissance covering a large area over a very limited time period. This report summarises the key evidence and findings from the reconnaissance.
