Super volcanoes and global effects

Super volcanoes are volcanic areas capable of super-eruptions where the magma is ejected in very large quantities. These large eruptions are left behind by a caldera formed as a result of the collapse. The large amount of material that is sprayed affects large areas in the world. For example, the ashes of the Toba volcano were found in the Greenland glacier cores. These large eruptions cause great damage to nearby environments, causing a decreasing in temperature at the global dimension. However, after a super-eruption, generally fertile soils are formed and the geothermal field is formed by a large number of hot water springs
