Mt Talua, reserved within one of the two national parks in Tonga, is one of the high points of Vava'u Island. It is entirely composed of coralline limestone and has been uplifted in a number of major tectonic movements. Vava'u as an island and as a group of islands is a maze of jig-saw puzzle pieces of atolls and patch reefs that have been uplifted, then have new reef grow around them, again and again. Sitting on the edge of the Australia Plate (Tonga Sub-Plate) the uplift is associated with the subduction of the Pacific Plate beneath, as the two plates approach each other at 10-15 cm/year.
