Topographic map of Tristan da Cunha

Tristan da Cunha is a remote group of volcanic islands in the south Atlantic Ocean. It is part of the British Overseas Territories and is considered one of the most isolated inhabited archipelagos in the world. The main island, also named Tristan da Cunha, is located approximately 2,400 kilometers (1,500 miles) from the nearest inhabited land, Saint Helena, and 2,800 kilometers (1,750 miles) from the nearest continental land, South Africa.

Geography

The main island of Tristan da Cunha is roughly circular with a diameter of about 11 kilometers (7 miles) and an area of 98 square kilometers (38 square miles). The island is dominated by the Queen Mary's Peak, a volcano that rises to 2,062 meters (6,765 feet) above sea level, making it the highest point in the territory. The peak is often covered in snow during the winter months.

The island's terrain is rugged and mountainous, with steep cliffs and limited flat land. The coastal areas are characterized by rocky shores and small beaches. The interior of the island is covered with lush vegetation, including ferns, mosses, and grasses. The island's climate is classified as marine, with mild temperatures and high humidity throughout the year.

Flora and Fauna

Tristan da Cunha is home to a unique ecosystem with several endemic species of plants and animals. The island's isolation has allowed for the development of species that are not found anywhere else in the world. Notable endemic species include the Tristan albatross, the Tristan thrush, and the Tristan rock lobster.

The island's vegetation includes a variety of native plants, such as the Phormium tenax (New Zealand flax) and the Empetrum rubrum (red crowberry). The island also supports a range of seabirds, including the Atlantic yellow-nosed albatross and the Sooty albatross.

Human Settlement

The only settlement on Tristan da Cunha is Edinburgh of the Seven Seas, located on the northwestern coast of the main island. The settlement is home to the island's entire population, which numbers around 250 people. The residents of Tristan da Cunha are primarily engaged in subsistence farming, fishing, and the production of handicrafts.
