New Zealand sits directly on the boundary between the Indo-Australian and Pacific plates — and the Alpine Fault, which runs 600 kilometers along the South Island, last ruptured in 1717. That is over 300 years ago. Current scientific consensus puts the probability of rupture at 75% within the next 50 years, with an 82% chance that rupture reaches magnitude 8 or greater. But the earthquake itself is only phase one. In this video we break down the chain reaction scientists have been quietly mapping for years — how an Alpine Fault rupture could trigger massive landslides into Lake Wakatipu, generating tsunami-like waves that reach Queenstown’s shoreline in minutes, after an event that has already left the city unable to respond.
