The Tonga Trench is located at the tectonic boundary between the Pacific Plate and the Indo-Australian Plate.

Explanation:

The Tonga Trench is a deep-sea tomb located in the South Pacific, near the Tonga Archipelago. With a maximum depth of about 10,890 meters, it is the second deepest sea trench in the world, after the Mariana trench. The Tonga trench is the most seismically active sea trench in the world. Together with the Kermadec trench, the Tonga trench constitutes a subduction zone in which the Pacific plate drops below the Indo-Australian plate.
