Implosion of Radio Network Building in Christchurch

The Radio Network Building in Christchurch was imploded at 8am on Sunday 5 August 2012. 63 kilograms of explosives were used and the collapse took less than 8 seconds.

The building was 14 storeys high and many of the buildings surrounding it had already been demolished. It was built in 1986 but  damage from the February 2011 earthquake meant it could not be saved.

The fall was spectacular and neat and even in the late afternoon, people were milling around, photographing the remains of yet another Christchurch building.
