A video about field trials conducted by the Department of Building and Housing at Queen Elizabeth II Park in Christchurch. Fifty kilograms of explosives are being used to simulate a magnitude-4 earthquake at a distance of 10 kilometres.

A video of the controlled explosion of a 40-tonne boulder above the Summit Road. The boulder is being removed using explosives after an assessment by United Research Services found that the rocks supporting the boulder have become unsafe.
Aerial footage of a site in Avondale where several liquefaction remediation options are being tested. Gelignite explosives have been buried throughout the site. These will be set off to simulate liquefaction caused by an earthquake. The result, if successful, will help EQC protect people's houses from future earthquakes, and settle land claims. The video was recorded using a drone aircraft.
