Volcanic islands usually range in size between 1 and 104 square kilometres (0.4 and 40 sq mi). [2] Islands above a certain size usually have fresh groundwater, while low islands often do not, so volcanic islands are more likely to be habitable.
Krakatoa (/ ˌ k r ɑː k ə ˈ t oʊ ə, ˌ k r æ k-/), also transcribed Krakatau (/-ˈ t aʊ /), is a caldera [1] in the Sunda Strait between the islands of Java and Sumatra in the Indonesian province of Lampung. The caldera is part of a volcanic island group (Krakatoa archipelago) comprising four islands.
Below is a list of new islands created since the beginning of the 20th century by volcanism, erosion, glacial retreat, or other mechanisms.

Map of world's major seamounts. A list of active and extinct submarine volcanoes and seamounts located under the world's oceans.

The volcanoes at mid-ocean ridges alone are estimated to account for 75% of the magma output on Earth. [1] Although most submarine volcanoes are located in the depths of seas and oceans, some also exist in shallow water, and these can discharge material into the atmosphere during an eruption.
Observations made of Jupiter’s moon Io during the Juno mission’s flybys helped astronomers confirm how and why Io became the most volcanic world in the solar system.
