New video shows massive fault line rupture
GNS has posted a new video showing the shocking rupture of the Kekerengu Fault.
The Kekerengu was one of several faults responsible for the M7.8 quake last Monday. It is closely related to the larger Hope Fault.
The Kekerengu Fault was one of at four faults identified by GeoNet as responsible. Joining it was the Hope Fault, which only saw minor movement, the Hundalee Fault, and a newly identified fault at Waipapa Bay.
Initial surveys on the Kekerengu Fault rupture show it to be about 30km long, with a maximum of 10 metres of horizontal displacement and 2 metres of vertical displacement.
GNS calculate the average movement of the fault to be around 20 to 25 metres every thousand years.
