@Caldera Official
A caldera is a large, cauldron-shaped depression formed when a volcano collapses after a massive eruption. This occurs when a magma chamber empties, causing the ground above to collapse into the void. Calderas can be several kilometers wide and deep, often filled with water to form lakes. They can be active or dormant, with active calderas posing a significant threat of future eruptions. Examples include Yellowstone Caldera in the US and Toba Caldera in Indonesia. Calderas are distinct from volcanic craters, which are smaller and formed differently. They showcase the powerful forces that shape our planet ¹ ².
