New Zealand quake 'broke the rules'
The 14 November 2016 Kaikoura earthquake in New Zealand may be one of the most complex ever studied using modern techniques.
The Magnitude 7.8 event ruptured a near-200km-long swathe of territory, shifting parts of NZ's South Island 5m closer to North Island.
Whole blocks of ground were buckled and lifted upwards, in places by up to 8m.
Prof Tim Wright from Leeds University, UK, explained to Adam Hart how earthquakes worked in New Zealand.
