Taranaki Volcano | John Seach


North Island, New Zealand

39.30 S, 174.07 E
summit elevation 2518 m

Mt Taranaki is an isolated cone in SW of the North Island of New Zealand. The volcano has a history of avalanches and lahars, produced from explosive eruptions.

Taranaki is the second tallest mountain on the North Island.

1655 Eruption
The Burrell Lapilli eruption of Mt Taranaki in 1655 produced a small lava dome effusion followed by an explosive sub-plinian phase that covered over 200 sq km of New Zealand's central North Island in tephra. Transition from effusive to explosive eruptions at andesitic volcanoes is determined by factors such as dyke propagation and sealing, degree of fractionation of magma, and magma ascent rate and magma volume.
