New Zealand – and specifically the Canterbury region - has become one of the most seismically active developed countries in the world. Since 2010, we've experienced many quakes ranging from barely felt to significantly destructive. Compared to other earthquake-prone areas of the world, this gives us relevant, recent experience that others don’t.

The Alpine Fault. Its next earthquake is overdue, making it quite possible that most Kiwis alive today will see it rupture in a magnitude-8 earthquake, leading scientists say. When it does, the entire South Island will be affected on some level; roads and railways broken or blocked, rivers dammed or diverted, many buildings damaged to some degree. Some towns will be cut off completely, possibly for months. And it’s not just the “big one” itself – there will be an entire sequence of multiple magnitude 7, 6 and 5 quakes rippling up and down the island for years afterward.
