Some Aspects of Quaternary History of Tongariro Volcanic Centre
thesis
posted on 2022-03-01, 01:02 authored by Wayne William ToppingThe Tongariro Volcanic Centre, at the southern end of the Taupo Volcanic
Zone, North Island, New Zealand, consists of five large andesite
volcanoes - Ruapehu, Tongariro, Ngauruhoe, Pihanga and Kaharamea-Tihia -
with several associated minor volcanoes and vents all of Quaternary
age. In the northern part of the Centre the north-westerly trending
Kakaramea-Tihia Massif and Pihanga form a chain of volcanoes which last
erupted more than 20,000 years BP, but from which large mudflows have
recurred up to as recently as 1910 A.D. By contrast the other two
multiple vent volcanoes - Ruapehu and the Tongariro Massif - include
several vents (four and possibly five) that have been active during the
last 100 years and, in particular, Ngauruhoe and Ruapehu Crater Lake.
