The Auckland volcanic field is an area of monogenetic volcanoes covered by much of the metropolitan area of Auckland, New Zealand's largest city, located in the North Island. The approximately 53 volcanoes[2] in the field have produced a diverse array of maars (explosion craters), tuff rings, scoria cones, and lava flows. With the exception of Rangitoto, no volcano has erupted more than once,[3][4] but the other eruptions lasted for various periods ranging from a few weeks to several years.[5] Rangitoto erupted several times[4] and recently twice; in an eruption that occurred about 600 years ago, followed by a second eruption approximately 50 years later.[6] The field is fuelled entirely by basaltic magma, unlike the explosive subduction-driven volcanism in the central North Island, such as at Mount Ruapehu and Lake Taupō.[7]
