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.

Empowered Christchurch Letter to Helen Beaumont
Articles, UC QuakeStudies
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'.

System Response of Liquefiable Deposits
Research papers, University of Canterbury Library
Results from a series of 1D seismic effective stress analyses of natural soil deposits from Christchurch are summarized. The analysed soil columns include sites whose performance during the 2010-2011 Canterbury earthquakes varied significantly, from no liquefaction manifestation at the ground surface to very severe liquefaction, in which case a large area of the site was covered by thick soil ejecta. Key soil profile characteristics and response mechanisms affecting the severity of surface liquefaction manifestation and subsequent damage are explored. The influence of shaking intensity on the triggering and contribution of these mechanisms is also discussed. Careful examination of the results highlights the importance of considering the deposit as a whole, i.e. a system of layers, including interactions between layers in the dynamic response and through pore water pressure redistribution and water flow.

Mapping shallow groundwater salinity in a coastal urban setting to assess …
Research Papers, Lincoln University
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.
