indian ocean
the trench is long and has a maximum depth of or 5.20 miles in the brownson deep, which is the deepest point in the atlantic ocean and the deepest point not in the pacific ocean. on december 19, 2018, its deepest point was identified by the "dssv pressure drop" using a state-of-the-art kongsberg em124 multibeam sonar and then directly visited and its depth verified by the manned submersible deep-submergence vehicle "dsv limiting factor" (a triton 36000/2 model submersible).

the eastern boundaries of the tonga and kermadec plates constitute the subduction zone of the pacific plate, characterized by a trench about 2,000 km in length. the trench is continuous, but has different names for different sections: hikurangi trench, the kermadec trench and the tonga trench. the tonga trench is the second deepest trench in the world at about 10,800 m, with the deepest point, horizon deep, being the deepest point in the southern hemisphere and the second deepest point in the world, after the challenger deep in the mariana trench. the eastern boundary of the kermadec plate is also the site of the kermadec trench, which is the fifth deepest trench in the world at about 10,000 m. the eastern boundary of the tonga plate is one of the fastest subduction zones with a rate of up to 24 cm/yr.
