What’s the deepest part of the Tonga Trench?
the Horizon Deep
Its deepest point is 10,882 m, a site known as the Horizon Deep, and it is separated from the neighboring Kermadec Trench in the south by the Tonga Platform, a sill that rises to approximately 5.5 km in depth (Fig. 1A).
Why does the Tonga Trench have deep earthquakes?
The Pacific crust that descends into the trench is old, 100–140 Ma, and relatively cold and it can therefore store a lot of elastic energy. As it reaches deep into the mantle, more than 600 km (370 mi), and encounters barriers, it is being contorted, which produces deep mantle earthquakes.
