A supervolcanic eruption is a massive volcanic event that can produce an enormous amount of ash and lava, significantly more than typical volcanic eruptions. These eruptions occur when magma from deep within the Earth builds up pressure and eventually breaks through the surface. The result can be a caldera, a large depression formed after the eruption, which can have devastating effects on the environment and climate. One of the most well-known supervolcanoes is Yellowstone, located in the United States. Supervolcanic eruptions can affect global temperatures, disrupt ecosystems, and pose serious risks to nearby populations. Scientists study these volcanoes to better understand their behavior and potential hazards.
