The Mangakino caldera complex or Mangakino volcanic center is the westernmost and oldest rhyolitic caldera volcano in the Taupō Volcanic Zone of New Zealand's North Island.[1] It produced about a million years ago (1 Ma) in the Kidnappers eruption of 1,200 km3 (287.9 cu mi), the most widespread ignimbrite deposits on Earth and was closely followed in time by the smaller 200 km3 (48.0 cu mi) Rocky Hill eruption.[2] The Kidnappers eruption had a estimated VEI of 8 and has been assigned a total eruption volume (not just tephra) of 2,760 km3 (662.2 cu mi). There were at least 11 major historic eruptions assigned to this complex.[3]
