A new video of the Kekerengu Fault shows the shocking damage caused by last week's 7.8-magnitude earthquake on the landscape.

The fault was one of several believed responsible for the large tremor which shook most of the country and changed the landscape around North Canterbury, including rupturing large cracks in the ground and raising the sea bed.

So far, satellite images had revealed huge changes in land movement across the Hope and Kekerengu faults, as well as several other faults in the region.
