As you might expect from a volcanic zone, there are numerous active volcanoes and geothermal fields in the area. Volcanic hazards information series 7. It began erupting about 300,000 years ago and the present day caldera was created by an eruption 27,000 years ago called the Oruanui Eruption. The Taupo Volcanic zone TVZ on New Zealands North Island is responsible for most of New Zealands current volcanic activity.The zone contains the volcanoes of Taupo,Tarawera and Rotorura. [Palmerston North, NZ]: Ministry of Civil Defence.


Taupo volcano first began to erupt over 300,000 years ago. Lake Taupo fills the large caldera volcano.

Orakei Korako lies right in the middle of … Froggatt, P. 1997 Volcanic hazards at Taupo Volcanic Centre. Taupo, the most active rhyolitic volcano of the Taupo volcanic zone, is a large, roughly 35-km-wide caldera with poorly defined margins. It extends some 350 kilometres from Mount Ruapehu and Mount Ngauruhoe at the southwestern tip, through Taupo, Rotorua and to Whakaari (or White Island). Taupo volcano last erupted over 1,800 years ago and is today filled by New Zealand's largest lake. The Taupo Volcanic Zone (TVZ), an area from the central North Island peaks to White Island in the Bay of Plenty, is the hub of all this activity, but further north, the Auckland Volcanic Field consists of around 50 individual prominences and there are numerous sea-mounts and small islands, including 25 submarine volcanoes within 400 km of the coast. Between this and the ‘Taupo Eruption’ (1800 years ago) there were at least 26 much smaller eruptions which formed lava domes and spread pumice and ash over nearby areas. It reviews the past volcanic history of Taupo, and explains the different types of eruptions that have occurred. The TVZ is an extensional feature called a back arc basin which allows magma from the mantle to well up near the crust causing more activity. Oruanui was the most recent, occurring 26,500 years ago. 26 p. Introduction. The Taupo Volcanic Zone is named after Lake Taupo, the largest volcano in the zone. It is a type example of an "inverse volcano" that slopes inward towards the most recent vent location. Although Taupo Volcano has much more violent eruptions than cone volcanoes, they are fortunately less frequent. This booklet is designed to inform you about the volcanic hazards of the Taupo area. Lake Taupo was formed by the massive Oruanui eruption, one of the largest volcanic eruptions in history.The volcanic explosivity index classified that eruption as "apocalyptic", one of only 47 eruptions identified as such. Of these, 42 occurred in the last 36 million years.
