This has made a huge mess for the residents to clean up. I heard on the news that homes have been damaged by subsidence in areas of earthquake-caused liquefaction like this.
Sandbags placed along the river bank to prevent flooding onto the road. The earthquake caused the ground in this area to subside , making it susceptible to flooding.

A damaged house in Avonside. The front of the house has sunk due to subsidence in the ground caused by liquefaction. Codes have been spray painted on the front window by the North Shore City Council rescue team.
The bridge on River Road just before the Banks Ave turn off. The bridge approach to the left subsided. Temporary repairs have been carried out but you can still see evidence of the amount of subsidence by the traffic island in the middle of the road.
A warning sign posted on River Road beside the Avon River reads "Health warning, contaminated water. Due to sewage overflows this water is unsafe for human contact and activity and is a public health risk. Please keep all people and pets out of contact with the water and do not cosume and seafood or shellfish collected from this area." The photographer comments, "A bike ride around the CBD. River Rd subsidence".
