The New Zealand Alpine Fault: Are we prepared?
Running approximately 850 kilometres along the spine of New Zealand’s South Island, the Alpine Fault marks the boundary between the Pacific and Australian tectonic plates. It’s one of the most extensively studied – and potentially most destructive – geological features in the Pacific Ring of Fire. Current science estimates a 75% probability of a magnitude 8+ rupture within the next 50 years.
Such an event would affect most of the South Island and the lower North Island – causing widespread structural damage, cutting key transport and utility links, and isolating some communities for weeks or even months.
This raises a critical question for organisations across New Zealand and beyond: Are we prepared?
New Zealand is a global leader in seismic research, hazard modelling and insurance solutions, with strong collaboration between scientists, government, emergency managers and the insurance sector. This creates a powerful opportunity for organisations to make informed, proactive decisions about resilience – before the next major event.
Our latest report examines the science of the Alpine Fault, outlines realistic impact scenarios, examines sector specific consequences, and sets out how New Zealand’s resilience and insurance systems can be leveraged for better decision making.
