This week marks the second anniversary of the magnitude 7.8 Kaikōura earthquake that ruptured a world record 25 faults in the upper South Island. GNS Science reflects on some of the key features and implications of this complex event – and talks to principal scientist Dr Kelvin Berryman about what we’ve learned.

Two years ago, a magnitude 7.8 quake near Kaikōura dramatically changed part of New Zealand’s landscape. This week, GNS Science experts look back on the most complex earthquake ever studied – and consider the implications for the future.

Researchers from GNS Science involved at all stages of the science value chain were this week honoured for their contributions to making New Zealand more resilient to geological hazards.
