Volcanology of New Zealand
Volcanology of New Zealand is the scientific study of volcanoes and volcanic phenomena in New Zealand. Volcanism has been responsible for many of the country's geographical features, especially in the North Island and the country's outlying islands.While the land's volcanic history dates back to before the Zealandia microcontinent rifted away from Gondwana 60–130 million years ago, activity continues today with minor eruptions occurring every few years. This recent activity is primarily due to the country's position on the boundary between the Indo-Australian and Pacific Plates, a part of the Pacific Ring of Fire, and particularly the subduction of the Pacific Plate under the Indo-Australian Plate.New Zealand's rocks record examples of almost every kind of volcanism observed on Earth, including some of the world's largest eruptions in geologically recent times.None of the South Island's volcanoes are active.
