Volcanoes are usually mountains (sometimes islands, lakes, plateaus, calderas, seamounts or lava domes) that are formed when magma (liquid rock) wells up from inside the Earth. There are also analogous formations away from the Earth. Many volcanoes are categorized both as volcanoes and other landforms, such as mountains (if qualified).

A topographic map of Ngorongoro Crater in northern Tanzania, the world's largest inactive, intact, and unfilled volcanic caldera, which formed when an immense volcano erupted and collapsed on itself 2–3 million years ago. The floor of the caldera is 600 metres (2,000 ft) below its rim and covers more than 260 square kilometres (100 sq mi).

The word volcano (UK: /vɒlˈkeɪnəʊ/; and US /vɔlˈkeɪnoʊ/) originates from the early 17th century, derived from the Italian vulcano, a volcanic island in the Aeolian Islands of Italy whose name in turn comes from latin volcānus or vulcānus referring to Vulcan, the god of fire in Roman mythology.
Volcanoes can be of different types such as cinder cone volcanoes, composite volcanoes, shield volcanoes, and lava domes. Each of these variations of volcanoes forms in its own way. Cinder cone volcanoes are the simplest type of volcano. This volcano forms from particles of solidified lava that ejected from a single vent.
Active volcanoes such as Stromboli, Mount Etna and Kīlauea do not appear on this list, but some back-arc basin volcanoes that generated calderas do appear. Some dangerous volcanoes in "populated areas" appear many times: Santorini six times, and Yellowstone hotspot 21 times.
