#Caldera @Caldera Official **Caldera**

A caldera is a large volcanic depression formed when a volcano collapses after a massive eruption empties its magma chamber. Calderas can span several kilometers and often create lakes, like Crater Lake in Oregon. They differ from craters, which are smaller and formed by explosive eruptions. Calderas may remain active, with potential for future eruptions, or become dormant. Famous examples include Yellowstone Caldera (USA), Santorini (Greece), and Taupō (New Zealand). Calderas also occur on other planets, like Olympus Mons on Mars. Their study helps scientists understand volcanic hazards and Earth’s geologic history.
