GNS Science has visualised how Monday mornings' massive earthquake rippled across the upper South and lower North Island.

The magnitude 7.8 earthquake struck at 12.02am on Monday November 14. The rupture started near Culverden at a depth of 15km.

A black dot marks the epicentre. Numerous red bands show the seismic waves that spill out from the various faults that are ruptured.

The red indicates strong-to-severe shaking while ground movement under the white patches was stronger still.

GNS says the predominantly northward rupture caused greater ground motion to the north which may explain why the earthquake caused more damage in Wellington than Christchurch.

The geoscience research centre estimates shaking lasted for two minutes in Kaikoura and around 30 seconds in Wellington.

The model runs at two times normal speed.
