#caldera @calderxyz A caldera is a large, circular depression that forms at the summit of a volcano following a massive eruption. It occurs when the volcano’s magma chamber empties rapidly during an eruption, causing the surface above to collapse. Unlike a typical volcanic crater, a caldera is much larger, often spanning several kilometers in diameter. Over time, calderas may fill with water, forming picturesque lakes like Crater Lake in Oregon, USA, or they may host renewed volcanic activity, creating smaller cones within the depression. Calderas are important geological features that help scientists study volcanic history, hazards, and geothermal potential. They are often sites of significant natural beauty but can also pose future volcanic risks.
