How many volcanoes in Auckland?

Answer 1

The biggest and most dangerous volcano in New Zealand and the world is actually Lake Taupo which is New Zealand's largest lake, and is located in the centre of the North Island. This volcano last erupted in the year 186 AD, and erupts approximately once every 2000 years. This eruption was over 50 times the magnitude of the Mt St Helen's eruption. Mt St Helens moved 3 cubic kilometers of earth, and Krakatoa (the biggest in recent times) in Indonesia moved 8 cubic kilometers, compared to 110 cubic kilometers for Taupo.

Answer 2

The biggest and most dangerous volcano in New Zealand and the world, is actually Lake Taupo which is New Zealand's largest lake, and is located in the centre of the North Island. This volcano last erupted in the year 186 AD, and erupts approximately once every 2000 years. New Zealand's largest active volcano is Mt Ruapehu.

Active volcano is white island in the bay of plenty (north island)

Dormant would be a toss up between Tarawera (central north island) and Rangitoto (island in Auckland city harbour, the waitamata)

Answer 3

This is not an easy question to answer, for an active and growing volcano will naturally bury early evidence with subsequent eruptions. The Taupo Volcanic Zone is one of the most active on Earth, and may be the most explosive.

However, Older volcanic activity dates back to when New Zealand was separating from Gondwana, some 60 - 130 million years ago. Traces of these old volcanoes are preserved in the South Island, in Marlbrough, and Shag Point in Otago.

The Median Batholith which extends from Fiordland to Nelson, dates from 375 to 105 million years ago, some of that time frame is before NZ's separation from Gondwana Land.

Answer 4

There are a little over 50 recognized volcanic craters in the Auckland Volcanic Field.There may be more, but these are now concealed by ejecta from a younger eruption, or lying underwater.

The earliest one is that of Onepoto, about 248 000 years ago. The most recent was that of Rangitoto, about 600 years ago. Eruptions have tended to become larger as time goes on, with Rangitoto contributing about 60% of the Field's total ejecta.

The most well recognised volcanoes within the field are:

Albert Park

Auckland Domain

Lake Pupuke

Mangere Mountain

One Tree Hill

Browns Island

Mount Cambria

Mount Eden

Mount Hobson

Mount Victoria

Mount Wellington

North Head
