Geonet recorded 878 events in the 24 hours after the monster 7.5-magnitude shock, more than 300 of them 4-magnitude or greater. Here Chris McDowall plots the quakes on an animated map.
This animation shows all the earthquake events recorded by GeoNet’s monitoring network between Palmerston North and Christchurch on Monday, November 14.
The big quake was 16km deep with a magnitude of 7.5 and struck at 12.02am. This was followed by hundreds of aftershocks. Including a cluster of three 6+ quakes in the first hour.
The dark lines on the map represent major faults.
Circles are coloured according to quake depth. The darkest circles occurred less than 20km from the surface. The palest circles represent events 60 km or deeper.
