The Kermadec Islands have no native land mammals, but are home to large colonies of seabirds which nest in the forests or on the coast. 35 bird species are known, at least three of which are unique to the Kermadecs. Since 1900, 40 M7.5+ earthquakes have been recorded, mostly north of 30°S. The tectonic boundary between the Indian-Australian and Pacific plates then changes to a transform fault. Today, the eastern boundary of the Tonga Plate is one of the fastest subduction zones, with a rate up to 24 cm/yr.

The trench and subduction zone continues northeast from the North Island to the Kermadec Islands, Tonga, and Samoa. Tectonic Summary. Tectonic Summary. The Tonga plate is located 2500km NNE of New Zealand. The Kermadec Plate is a very long and narrow tectonic plate located west of the Kermadec Trench in the south Pacific Ocean. Also included on this tectonic plate is a small portion of the North Island of New Zealand and the Kermadec Islands . Kermadec Islands, volcanic island group in the South Pacific Ocean, 600 mi (1,000 km) northeast of Auckland, New Zealand; they are a dependency of New Zealand. This chapter examines their origins. The Kermadec Islands consist of 13 islands and islets, located between 800km and 1000km north-east of New Zealand. The Kermadec-Tonga subduction zone is a convergent plate boundary that stretches from the North Island of New Zealand northward. The Kermadec Plate is a very long and narrow tectonic plate located west of the Kermadec Trench in the south Pacific Ocean.

Also included on this tectonic plate is a small portion of the North Island of New Zealand and the Kermadec Islands.It is separated from the Australian Plate by a long divergent boundary which forms a back-arc basin.This area is highly prone to earthquakes and tsunami. It is located to the East of the Southern Alps.

The tectonic boundary between the Indian-Australian and Pacific plates then changes to a transform fault. The Kermadec-Tonga subduction zone generates many large earthquakes on the interface between the descending Pacific and overriding Australia plates, within the two plates themselves and, less frequently, near the outer rise of the Pacific plate east of the trench. the Kermadec Plate. Tectonic Summary The October 21, 2011, M 7.4 Kermadec Islands region earthquake occurred as the result of shallow reverse faulting near the Kermadec Trench where the Pacific plate begins its descent into the mantle beneath the eastern edge of the Australia plate. The Kermadec Islands are the summits of large volcanoes that have been built up on the crest of the Kermadec Ridge, and have emerged above sea level.

It is separated from the Australian Plate by a long diverge The islands are volcanoes of the Kermadec Ridge, pushed up by the Pacific Plate which subducts into the deep Kermadec Trench.. It is separated from the Australian Plate by a long diverge The formation of the Kermadec and Tonga Plates started about 4–5 million years ago. The July 6, 2011, M 7.6 Kermadec Islands region earthquake occurred as the result of shallow normal faulting near the Kermadec Trench where the Pacific plate begins its descent into the mantle beneath the eastern edge of the Australia plate. The Kermadec Plate is a very long and narrow tectonic plate located west of the Kermadec Trench in the south Pacific Ocean. Alpine Fault: In the Southern Island of New Zealand this fault system becomes the Alpine fault. Since 1900, 40 M7.5+ earthquakes have been recorded, mostly north of 30°S. Also included on this tectonic plate is a small portion of the North Island of New Zealand and the Kermadec Islands. The trench and subduction zone continues northeast from the North Island to the Kermadec Islands, Tonga, and Samoa. The Kermadec Plate is a very long and narrow tectonic plate located west of the Kermadec Trench in the south Pacific Ocean.

The September 29, 2008, M 7.0 Kermadec Islands earthquake occurred as the result of shallow reverse faulting within the Tonga-Kermadec subduction zone, which extends north-northeast from the North Island of New Zealand for more than 2,500 km through Tonga to within 100 km of Samoa. Macauley and Raoul account for over 95% of the land. It’s is bounded to the Southwest by a spreading center with the Australian plate, to the northwest by a spreading centers with the Niuafo’ou micro-plate and by a transform zone to the South with the Kermadec plate.
