A video recording of a lecture presented by Associate Professor Misko Cubrinovski as part of the 2011 University of Canterbury Earthquake Lecture Series.
Stage IV of the Christchurch liquefaction study updated the Stage II liquefaction hazard and ground damage maps with further data collected from other organisations, and included two additional maps indicating liquefaction sensitivity to groundwater levels. Stage IVa of the Christchurch liquefaction study used revised groundwater levels and adjustments to the liquefaction prediction algorithm. The outputs of the report were liquefaction hazard and ground damage maps for both average summer (low) and average winter (high) groundwater levels. The maps produced as part of Stage IVa of the report were subsequently included in an Environment Canterbury public education poster The Solid Facts on Christchurch Liquefaction which also contained information on how liquefaction occurs and what can be done to mitigate the liquefaction hazard. Stage IV of the Christchurch liquefaction study contained a number of recommendations to improve the liquefaction potential and ground damage maps for Christchurch. See Object Overview for background and usage information.
Liquefaction silt on a grassed area in New Brighton.
Liquefaction silt. The photographer comments, "After the earthquake in Christchurch New Zealand, liquefaction covered the streets, but after it had risen from below ground whilst the ground was shaking it the liquid in the liquefaction wanted to drain away".
Dried liquefaction silt in North New Brighton. The photographer comments, "Wet liquefaction after an earthquake can soon start to dry up".
A brochure published by Environment Canterbury in January 2003, examining liquefaction and liquefaction hazard ratings.
Liquefaction silt in Bexley. The photographer comments, "This is not really a worm but a sliver of liquefaction that has fallen out of a tyre tread".
Liquefaction in North New Brighton. The photographer comments, "After the double quake local to my home, the liquefaction made strange shapes in the liquid content of the outpourings".
Dried liquefaction silt in North New Brighton. The photographer comments, "Here you can see the very fine surface layer of liquefaction starting to shrink, crack and then curl up on itself".
A report detailing the Liquefaction Trial, the observations, and discussions of the trial interpretation and findings.
A video filmed during the Liquefaction Trial detonation and immediately following (run time approximately one minute).
A brochure created by Environment Canterbury in August 2007, covering liquefaction in Christchurch and including a liquefaction map.
Liquefaction silt and sand cover the lawn of a residential property. The photographer comments, "This is a garden inundated with liquefaction. Though most liquefaction is grey in Christchurch there must have been golden sandy beaches before the volcanoes erupted millions of years ago".
Grass growing through liquefaction silt in Avondale. The photographer comments, "Although this grass seems to be growing on the liquefaction created by the earthquakes in Christchurch, New Zealand, they are actually only growing through it. Nothing seems to grow even though seeds will sprout almost anywhere else. The seeds are growing in the soil which got covered up by the liquefaction. If liquefaction gets mixed with even a little soil then nature can get a foothold".
Workers using a shovel and a wheelbarrow to clear liquefaction from a property. The liquefaction is being piled out the front where it will be collected.
Piles of liquefaction on the side of the road in Avonside. The liquefaction has been dug out of people's properties and placed on the road to be picked up by the council. The power boxes and the power pole to the left are on a lean due to liquefaction.
Stage IV of the Christchurch liquefaction study updated the Stage II liquefaction hazard and ground damage maps with further data collected from other organisations, and included two additional maps indicating liquefaction sensitivity to groundwater levels. See Object Overview for background and usage information.
Liquefaction in North New Brighton. The photographer comments, "This is the liquid part of liquefaction left when the heavier sand content has dropped down. After the double quake in Christchurch local to me I found these strange lines of bubbles on the surface".
