Major volcanoes of New Zealand

Volcanoes are present throughout New Zealand as the country lies along the edge of the Pacific Plate, a part of the Pacific Ring of Fire. Volcanic activity has been responsible for much of the geographical features, and eruptions of some of the major volcanoes occur regularly.

Geology

This section needs expansion. You can help by adding to it.

One of the largest eruptions in the world occured around 200 AD, when Lake Taupo errupted, altering the geology of much of the North Island. The Taupo Volcanic Zone is merely one of New Zealand's fields. Auckland comprises a large, dormant field, made up of over fifty cones, the most recent of which to errupt was Rangitoto, 600-700 years ago. Other volcanoes are more recently active, including Tarawera, Mount Taranaki, Tongariro, Ngauruhoe, Ruapehu and White Island.

Major erruptions

This section needs expansion. You can help by adding to it.

Over six hours on June 10 1886, Mount Tarawera errupted, spewing ash and debris over 16,000 km2, destroying the Pink and White Terraces, and three villages, including Te Wairoa, and claiming the lives of at least 153 people. Approximately 2 cubic kilometres of tephra was erupted.
