Christchurch Liquefaction Viewer

Description

This website presents information about the liquefaction hazard in Christchurch City. Most of this information is not new, it's simply gathered together in one place to make it easier to access. We learned a lot about liquefaction from the Canterbury Earthquakes. But liquefaction doesn’t always occur in the same pattern, so it’s important to understand what could happen in future earthquakes. This information can be important when deciding how to construct buildings and infrastructure, and when planning for future development of the city.

You can browse by clicking on the six tabs across the top of the page:

• About – How liquefaction occurs and its consequences.
• Liquefaction Lab – Experiment with different scenarios to see how these impact liquefaction damage.
• Vulnerability Map – A map showing how liquefaction vulnerability varies across Christchurch.
• Earthquake Maps – Observations from the 2010-2011 Canterbury earthquakes.
• Other Maps – General information about ground conditions across Christchurch.
• Compare Maps – Place any two of these maps side-by-side to use the slider to compare them.

You can select a location by clicking on the map or using the address search box. The + symbol on the map shows the selected location, and the green outline shows the surrounding area with similar ground conditions which has been grouped together for the analysis in the Liquefaction Lab tab.
