Below is a list of new islands created since the beginning of the 20th century by volcanism, erosion, glacial retreat, or other mechanisms. One of the most famous new volcanic islands is the small island of Surtsey, located in the Atlantic Ocean south of Iceland. It first emerged from the ocean surface in 1963.
Andesite and basaltic andesite are the most abundant volcanic rock in island arc which is indicative of the calc-alkaline magmas. Some Island arcs have distributed volcanic series as can be seen in the Japanese island arc system where the volcanic rocks change from tholeiite—calc-alkaline—alkaline with increasing distance from the trench.

The Aleutian Islands and adjoining Alaskan Peninsula are an example of such a subduction zone. The active front of a volcanic arc is the belt where volcanism develops at a given time. Active fronts may move over time (millions of years), changing their distance from the oceanic trench as well as their width.
This list includes all islands in the world larger than 1,000 km 2 (390 sq mi). For size and location reference, the four continental landmasses are also shown. Continental landmasses Continental landmasses are not usually classified as islands despite being completely surrounded by water. [Note 1] However, because the definition of continent varies between geographers, the Americas are ...
