Natural Environment

The natural environment includes the air, water, land, biodiversity, and their ecosystems. A healthy natural environment allows a city and its people to thrive. Here is what we have to share.

Economic impact of liquefaction

The 2010-2011 Canterbury Earthquake Sequence has had an enormous economic impact on Christchurch and New Zealand. Liquefaction-induced damage from the earthquakes has significantly exacerbated the eco...

Foundation damage

Geotechnical engineers have inspected more than 60,000 residential properties for possible liquefaction-induced land damage after the 2010-2011 Canterbury Earthquake Sequence.

Ground surface subsidence

The 2010-2011 Canterbury Earthquake Sequence caused regional tectonic subsidence and uplift. The earthquakes also triggered widespread liquefaction, contributing to subsidence and localised lateral sp...

Lateral spreading

Horizontal ground movements related to liquefaction occurred across greater Christchurch following the 2010-2011 Canterbury Earthquake Sequence. Information including aerial LiDAR and aerial photograp...

Liquefaction-related land damage

The Canterbury Earthquake Sequence of 2010-2011 triggered widespread liquefaction and land damage throughout the region.   Land damage varied across the region with severity influenced by two main fa...

Localised ground surface changes

Liquefaction of underlying soil layers can cause slumping of elevated areas displacing the liquefied soils sideways. In addition to the liquefaction related subsidence, this slumping increases the ris...

Paleoliquefaction

Paleoliquefaction is the preserved evidence of liquefaction in the soil profile attributed to seismic events occurring before earthquake records began.   Following the 2010-2011 Canterbury Earthquake...

Residential Ground Improvement: Findings from trials to manage liquefaction vulnerability

The Canterbury Earthquake Sequence of 2010-2011 triggered widespread liquefaction. In some areas this resulted in consequential land and building damage.     The Ground Improvement Programme is an...

We sat down with people who gained a lot of experience from working in recovery and together we identified five common themes. These themes help us understand the learning from the Canterbury recovery.
