This one was really flowing out of the ground.
Sullivan Park in Avonside. Liquefaction can be seen running across the park. Two signs have slumped towards each other. Blue pipes carrying a temporary water supply to the neighbourhood have been placed across the park.
Paradise ducks search for food among 'sand volcanoes' in the Heathcote Estuary. The volcanoes were caused by liquefaction where the soil lost its strength and water erupted out of the hole, taking silt with it.

A photograph of members of the Wellington Emergency Management Office examining the car park in the basement of the Copthorne Hotel. The car park has flooded, and water has risen to where they are standing.
A copy of a letter from Hugo Kristinsson which was sent to Helen Beaumont, Manager of the Natural Environment and Heritage Unit at the Christchurch City Council, on 17 June 2014. The letter was sent on behalf of Empowered Christchurch. It is about legislation which, according to Kristinsson, determines land below the mean high water spring to be public land. Kristinsson is concerned that this legislation will cause 'hundred or even thousands' of people to lose their assets. He urges the Council to 'have the land surveyed and to redefine the CMA [Crown Minerals Act] before land claims are settled'.
A view over the top of a cordon fence. A digger sits on a mound of dirt, and water fills the former basement of the ANZ building on Hereford Street. The partially-demolished BNZ building can be seen in the background.

These were scattered across the park.

A photograph of street art on the side of the Couplands Bakery on Hawke Street in New Brighton. The artwork includes the tag "Aroha" and a painting of a man and a young child playing in the water.
A PDF copy of a fact sheet about hydraulic fracturing (fracking) in the South Island created by Anglican Advocacy in 2011. The fact sheet contains information about the possible impacts of fracking on water and the risk of earthquakes.
Water has swept grit and splinters of wood onto the footpath outside the Durham Street Methodist Church. In the background of the photograph a piece of one of the church's roof beams with its steel brace can be seen.
A photograph of the earthquake damage to a property in the Christchurch central city. Part of the roof of the property has collapsed, spilling material onto the balcony below. A sign in the foreground reads, "Wots your councillor doing for your water?".
Trees alongside the Avon River in Richmond. The river level is high, and the water is grey with silt. One of the trees is leaning towards the river. The photographer comments, "High river levels because of liquefaction in the Avon. Near 373 River Rd, Richmond".
Sand volcanoes put the silt all over the road.
The earthquake knocked over the bird bath.
Debra points at the beginnings of a sand volcano not long after the big earthquake.
An usual thing to see coming from the ground in Hoon Hay, Christchurch.

Study region: Christchurch, New Zealand. Study focus: Low-lying coastal cities worldwide are vulnerable to shallow groundwater salinization caused by saltwater intrusion and anthropogenic activities. Shallow groundwater salinization can have cascading negative impacts on municipal assets, but this is rarely considered compared to impacts of salinization on water supply. Here, shallow groundwater salinity was sampled at high spatial resolution (1.3 piezometer/km²), then mapped and spatially interpolated. This was possible due to a uniquely extensive set of shallow piezometers installed in response to the 2010–11 Canterbury Earthquake Sequence to assess liquefaction risk. The municipal assets located within the brackish groundwater areas were highlighted. New hydrological insights for the region: Brackish groundwater areas were centred on a spit of coastal sand dunes and inside the meander of a tidal river with poorly drained soils. The municipal assets located within these areas include: (i) wastewater and stormwater pipes constructed from steel-reinforced concrete, which, if damaged, are vulnerable to premature failure when exposed to chloride underwater, and (ii) 41 parks and reserves totalling 236 ha, within which salt-intolerant groundwater-dependent species are at risk. This research highlights the importance of determining areas of saline shallow groundwater in low-lying coastal urban settings and the co-located municipal assets to allow the prioritisation of sites for future monitoring and management.
