A desert island is an island with no people. Typically, a desert island is denoted as such because it exists in a state of being deserted, or abandoned. Note that an arid desert climate is not typically implied; one dictionary uses the phrase 'desert island' to illustrate the use of 'desert' as an adjective meaning "desolate and sparsely occupied or unoccupied".[4] According to another, "A desert island is a small tropical island, where nobody lives or an undiscovered island."

Over long periods of time, this type of island is eventually "drowned" by isostatic adjustment and eroded, becoming a seamount. Plate movement across a hot-spot produces a line of islands oriented in the direction of the plate movement. An example is the Hawaiian Islands, from Hawaii to Kure, which then extends beneath the sea surface in a more northerly direction as the Emperor Seamounts. Another chain with similar orientation is the Tuamotu Archipelago; its older, northerly trend is the Line Islands. The southernmost chain is the Austral Islands, with its northerly trending part the atolls in the nation of Tuvalu. Tristan da Cunha is an example of a hotspot volcano in the Atlantic Ocean. Another hot spot in the Atlantic is the island of Surtsey, which was formed in 1963.
