Note: Caldera names tend to change over time. For example, Ōkataina Caldera, Haroharo Caldera, Haroharo volcanic complex, and Tarawera volcanic complex all had the same magma source in the Taupō Volcanic Zone. Yellowstone Caldera, Henry's Fork Caldera, Island Park Caldera, Heise Volcanic Field all had Yellowstone hotspot as magma source.
Take Iceland, for example. With the region facing numerous eruptions from a volcano since the end of 2023, dramatic photos and video show lava shooting from a long fissure that opened up.

When the volcano is extinct, a plug forms on its vent, over time due to erosion, the volcanic cone slowly erodes away leaving the resistant lava plug intact. [2] Cinder Hill , a feature of Mount Bird on Ross Island , Antarctica , is a prominent example of a dissected volcano.
On Earth, volcanoes are most often found where tectonic plates are diverging or converging, and because most of Earth's plate boundaries are underwater, most volcanoes are found underwater. For example, a mid-ocean ridge, such as the Mid-Atlantic Ridge, has volcanoes caused by divergent tectonic plates whereas the Pacific Ring of Fire has ...
