Liquefaction and flooding in Waitaki Street, Bexley. The photographer comments, "Waitaki Street a week after the Christchurch Earthquake. Because of the damage to the drains and liquefaction in the area the streets are not drying out".
A video of a residential area in Christchurch, recorded in December 2011. The video captures a 6.0 magnitude earthquake, and the liquefaction caused by this tremor.
People walking amongst silt in Hagley Park shortly after the 22 February 2011 earthquake. These silt deposits were caused by the soil liquefying during the 22 February 2011 earthquake. The water flowed out, bringing sand with it.

Flooding and liquefaction surround a house in Richmond. Bricks have fallen from the walls of the house, exposing the wooden framework beneath.
In the aftermath of the 22 February 2011 earthquake, the Natural Hazards Research Platform (NHRP) initiated a series of Short Term Recovery Projects (STRP) aimed at facilitating and supporting the recovery of Christchurch from the earthquake impacts. This report presents the outcomes of STRP 6: Impacts of Liquefaction on Pipe Networks, which focused on the impacts of liquefaction on the potable water and wastewater systems of Christchurch. The project was a collaborative effort of NHRP researchers with expertise in liquefaction, CCC personnel managing and designing the systems and a geotechnical practitioner with experience/expertise in Christchurch soils and seismic geotechnics.
A long line of cars on Shirley Road. While the centre of the road is clear, there is flooding and liquefaction along the edges.
A small boy is being a real entrepreneur after the Christchurch earthquake of 22 February 2011 and has set up a road-side stall from which you can buy a bag of 'real leakyfakshun'. Behind him is a pile of liquefaction and a spade with which he can fill bags. Context - the Christchurch earthquake of 22 February has caused vastly more liquefaction than the original 4th September earthquake. The vibrations from the quake cause liquefaction which is where the soil loses strength and stiffness, and behaves more like a liquid than a solid - rather like wet sand.

Road damage and liquefaction in a residential street. The photographer comments, "A great gouge in the road caused by liquefaction undermining the road surface and a car driving over it. This was the earthquake in Christchurch, New Zealand on 22 February 2011".
A digger scrapes up liquefaction silt from Warden Street in Shirley, while workers with shovels look on. The photographer comments, "Clearing silt in Warden St".
A car mired in liquefaction in a car park on Chester Street in the aftermath of the 22 February earthquake. Behind it, the collapsed Durham Street Methodist Church can be seen.
Liquefaction surrounds a car on Hendon Street in St Albans, near the corner with Hills Road. In the background, 'keep clear' tape cordons off the front of a property.
A large crack in the ground at Sullivan Park in Avonside which has resulted from the 4 September 2010 earthquake. Remnants of liquefaction silt can be seen around the edges of the crack.

Damage to Christchurch city following the 22 February earthquake 2011. A car sits in a hole created by liquefaction on Ferry Road. Piles of silt can be seen around the car.
Damage to River Road in Richmond. The road surface is badly cracked and slumped, and liquefaction silt covers part of the road. The photographer comments, "Lateral spreading cracks in River Rd".
Liquefaction erupted throughout the city during each of the major earthquakes. It had to be cleared and everyone piled it onto the roadside, where it was eventually picked up by City Council trucks. The fine dust permeated the air for weeks, driving many to wear dust masks while outside.

The cartoon shows two images of cars nose-down in ditches, the first is caused by 'liquifaction' and the second by 'stupifaction'. Context: there was another large aftershock on Boxing Day in Christchurch which resulted in quite a lot of liquefaction. There is always concern over the Christmas holidays about drinking while driving. Other Titles - Liquefaction Quantity: 1 digital cartoon(s).
The 22 February 2011, Mw6.2-6.3 Christchurch earthquake is the most costly earthquake to affect New Zealand, causing 181 fatalities and severely damaging thousands of residential and commercial buildings, and most of the city lifelines and infrastructure. This manuscript presents an overview of observed geotechnical aspects of this earthquake as well as some of the completed and on-going research investigations. A unique aspect, which is particularly emphasized, is the severity and spatial extent of liquefaction occurring in native soils. Overall, both the spatial extent and severity of liquefaction in the city was greater than in the preceding 4th September 2010 Darfield earthquake, including numerous areas that liquefied in both events. Liquefaction and lateral spreading, variable over both large and short spatial scales, affected commercial structures in the Central Business District (CBD) in a variety of ways including: total and differential settlements and tilting; punching settlements of structures with shallow foundations; differential movements of components of complex structures; and interaction of adjacent structures via common foundation soils. Liquefaction was most severe in residential areas located to the east of the CBD as a result of stronger ground shaking due to the proximity to the causative fault, a high water table approximately 1m from the surface, and soils with composition and states of high susceptibility and potential for liquefaction. Total and differential settlements, and lateral movements, due to liquefaction and lateral spreading is estimated to have severely compromised 15,000 residential structures, the majority of which otherwise sustained only minor to moderate damage directly due to inertial loading from ground shaking. Liquefaction also had a profound effect on lifelines and other infrastructure, particularly bridge structures, and underground services. Minor damage was also observed at flood stop banks to the north of the city, which were more severely impacted in the 4th September 2010 Darfield earthquake. Due to the large high-frequency ground motion in the Port hills numerous rock falls and landslides also occurred, resulting in several fatalities and rendering some residential areas uninhabitable.
A photograph captioned by BeckerFraserPhotos, "The Hague family in the family room area of their home at 7 Ching Gardens in Horseshoe Lake. They lived here after clearing away the liquefaction from September 2010, but the extent of liquefaction from the February 2011 earthquake was too great and they left their home on 22 February".
