There was a “domino effect, as the earthquake rupture jumped from fault to fault, essentially ‘unzipping' along a 150-kilometer length of the northeast coast of the South Island,” wrote Natalie Balfour of New Zealand’s earthquake monitoring agency, GeoNet, in a blog post. The rupture began about 15 kilometers underground near the town of Culverden. The event is still being investigated, but at the time EARTH went to press, at least 10 faults are reportedly thought to have been involved. Known as the Kaikoura earthquake, it is the largest quake to hit New Zealand since 2009, and it appears that the rupture jumped from one fault to another multiple times as it propagated.
