#Caldera
Caldera is a Spanish word for a cauldron, and in geology, it refers to a large, cauldron-like depression formed after a volcanic eruption. This occurs when a volcano erupts so violently that it empties the magma chamber beneath it. The unsupported rock above then collapses, creating a large, circular, or elliptical basin. These depressions can be several kilometers in diameter and are often filled with water, forming caldera lakes. A notable example is Crater Lake in Oregon, which formed over 7,700 years ago from the collapse of Mount Mazama. Calderas are a testament to the immense power of volcanic forces.
