At its northern end the Tonga Trench bends west into the microplates, interconnected spreading centres, and deformation zones of the Lau Basin. But the Tonga Trench also has a continuation in the inactive Vitiaz Trench (north of map area) with which it formed a single continuous trench before the opening of the North Fiji Basin (west of map area).
The Kermadec–Tonga subduction zone is a convergent plate boundary that stretches from the North Island of New Zealand northward. The formation of the Kermadec and Tonga plates started about 4–5 million years ago. Today, the eastern boundary of the Tonga plate is one of the fastest subduction zones, with a rate up to 24 cm/year (9.4 in/year ...

The Tonga–Kermadec Ridge is an oceanic ridge in the south-west Pacific Ocean underlying the Tonga–Kermadec island arc.It is a result of the most linear, fastest converging, and seismically active subduction boundary on Earth, the Kermadec–Tonga subduction zone, and consequently has the highest density of submarine volcanoes.

A team of Chilean and American scientists ventured to a place where no human has ever gone before. And although it may sound like a space voyage straight out of a Star Trek episode, this real-life ...
The Kermadec Trench is one of Earth's deepest oceanic trenches, reaching a depth of 10,047 metres (32,963 ft). [3] Formed by the subduction of the Pacific Plate under the Indo-Australian Plate, it runs parallel with and to the east of the Kermadec Ridge and island arc. The Tonga Trench marks the continuation of subduction to the north.
A map depicting the location of Tonga Trench. Microbial metabolism is the means through which microbes in any given environment obtain energy and nutrients. This encompasses an understanding of substrate oxidation and dissimilation reactions through which bacteria can generate energy as well as facilitate the uptake and release of inorganic or ...
