The Kaikoura earthquake moved parts of the the South Island more than 5 metres closer to the North Island!
Scientists looking into the earthquake have said the rupture so was unusual it could forever change the way scientists think about earthquake hazards.
Scientists say the earthquake’s characteristics could not have been predicted by existing models. The Kaikoura earthquake was much more complex that any other studied.
It confirmed that at least 21 faults, some of them previously unknown, had ruptured across two active fault domains that were not known to be connected.
The rupture took about two minutes to travel from its starting point near Culverden to its end point north of Kaikoura, 180 kilometres away.
Where it peaked, on the Kekerengu fault north of Kaikoura, researchers found up to 12 metres of horizontal displacement on the surface, which would have happened nearly instantaneously.
Its complexity would have implications for seismic hazard models around the world.
