Calderas is a city located in Venezuela. While the provided source material does not offer specific geographical details or cultural highlights regarding this particular municipality, it defines the geological term "caldera" as a large cauldron-like hollow formed by the collapse of a magma chamber following a volcanic eruption.
Geologically, a caldera is distinguished from a crater because it forms through subsidence and collapse rather than an explosion or impact. These features can reach diameters of dozens of kilometers and are considered rare events, with only nine known occurrences between 1911 and 2022. Volcanoes that develop these structures are frequently referred to as caldera volcanoes.
