Kermadec Islands
The Kermadec Islands are a remote volcanic island group in the South Pacific, part of New Zealand and lying northeast of the North Island.
Raoul Island: The largest and northernmost major island in the Kermadec group, formed by an active volcano. Its caldera, settlements, and research station anchor human activity across the group.
Subduction: The descent of one tectonic plate beneath another into the mantle. Pacific Plate subduction beneath the Australian Plate feeds the Kermadec volcanic arc.
Curtis Island: A small volcanic island in the southern Kermadec group, with active geothermal features. Its hot springs and fumaroles expose volcanic activity beyond Raoul Island.
Kermadec Islands flora: The plant life of the Kermadec Islands, including native forest and coastal vegetation. The islands’ subtropical forests reflect their isolated oceanic setting.
Kermadec Trench: A deep ocean trench east of the Kermadec Islands where the Pacific Plate descends beneath the Australian Plate. This subduction zone drives the region’s earthquakes and volcanic activity.
Kermadec-Tonga subduction zone: A convergent plate boundary where the Pacific Plate descends beneath the Australian Plate from the Kermadec region toward Tonga. Its motion produces the deep trench and active volcanism near the islands.
L'Esperance Rock: A steep volcanic rock in the southern Kermadec Islands, also known by its Māori name, Pukeahurangi. It is a striking, largely uninhabited outpost at the group’s southern end.
Kermadec Islands fauna: The animal life of the Kermadec Islands, including seabirds, marine mammals, and endemic invertebrates. Large seabird colonies and distinctive wildlife thrive far from mainland pressures.
Kermadec Ridge: A submarine volcanic ridge extending northeast from New Zealand through the Kermadec region. The islands rise above sea level along this undersea volcanic arc.
Kermadec volcanic arc: A chain of volcanoes formed above the Pacific–Australian plate boundary in the southwest Pacific. The islands are its emergent northern section.
