Volcanoes
Active volcanoes and the ground older ones left behind, and the ways people and wildlife live with them.

The volcano places include craters people live in and the shapes that older eruptions left behind. On Aogashima, an island administered by Tokyo, a village sits inside a double caldera. In Cabo Verde, Chã das Caldeiras was rebuilt on the lava that buried it. Kīlauea, on the Island of Hawaiʻi, grew a lake in its crater and then boiled it off in ninety minutes. Older volcanoes leave other forms: Crater Lake in Oregon fills the hollow left by the collapse of Mount Mazama about 7,700 years ago, and ships enter Deception Island's flooded centre through a narrow channel called Neptune's Bellows. On an island in the Azores, vines grow inside walls of black basalt.

Heights as each place's page states them, drawn from sea level to one vertical scale; widths and shapes are not to scale.
Not drawn: their pages give no summit height
- Cirque de Mafate gives its ramparts, to c. 1,000 m
- Crater Lake gives a depth instead: 592 m (National Park Service)

The summits use only heights stated on the places' own pages, at one scale. A place without a stated height is listed, not guessed. Each place page names its sources and the date it was checked.
