This may seem a bizarre request. As the earthquake hit Christchurch in Feb a number of videos were being circulated. One which was particularly interesting and I was telling my son about it yesterday. However I can't find it anywhere. It was taken from the gondola - or at the top - just as the quake hit and you could see the dust cloud rising. My son has always had an interest in natural phenomenon and I said he should see this. Does anyone know or remember the video and point me in the right direction? I have looked on youtube and searched via google.
