Located in Oceania, Tonga is an archipelago in the South Pacific Ocean, directly south of Western Samoa and about two-thirds of the way from Hawaii to New Zealand. Its 176 islands, 36 of them inhabited, are divided into three main groups – Vava’u, Ha’apai, and Tongatapu – and cover an 800-kilometre (500-mile)-long north-south line. The largest island, Tongatapu, on which the capital city of Nuku alofa is located, covers 257 square kilometres (99 sq mi). Geologically the Tongan islands are of two types: most have a limestone base formed from uplifted coral formations; others consist of limestone overlaying a volcanic base.
