New video footage of Monday's earthquake shows the full force of the 6.3 tremor.



The three minute video clip merges images taken from 12 cameras in the Dyers Road Building Centre.



The video first depicts a normal scenario of shoppers and staff at the Christchurch store.



But it soon turns into a very different scenario as shelves start shaking violently, and items including rakes, paint, ladders and computers topple down.



Shoppers and staff try to avoid the falling stock while running for the store's exits.



Operations Manager Aaron Pringle says the February 22 quake cut the power supply to the building and knocked the servers off the counter so there were no images from that event but it caused significantly more damage than the 2.20pm quake on Monday.



"We lost one can of paint on Monday and nearly all of them in February." The store also lost a lot of stock and one member of its team was killed while working at a building site.



Pringle said no one was injured on Monday but people were "thrown around like rag dolls".



"We were quite lucky there weren't many people in the store - only four or five customers and five staff," Pringle said.



Sales administrator David Nutsford, who has a special interest in video editing, collated the footage and added music.



The video was put on Youtube on Wednesday.



Pringle says the response has been "unbelievable".



"We've had people say we're insensitive to put music to it and making it more dramatic," he said. "The concept wasn't to upset people. We wanted to show what it was like at our store. When you view video like that and show people been thrown around people start to understand the sheer impact of these quakes."
