A volcano (from the mythological god Vulcan) is a conduit that puts the upper part of the solid crust in direct communication with the lower levels of the crust. It is also a geological structure through which magma (molten rock) emerges in the form of lava and gases from the interior of the planet. The ascent usually occurs in episodes of violent activity called "eruptions", which may vary in intensity, duration and frequency; being from conduits of lava flows to extremely destructive explosions. They generally acquire a characteristic conical shape that is formed by the pressure of the underground magma as well as the accumulation of material from previous eruptions. Above the volcano we can find its crater or caldera.

The lava that flows from this volcano in the jungles of the Congo is a different image. Nyirangongo lava has very little silica that is responsible for thickening and decelerating lava. In the year 2002, lava sprang from its mouth and dropped at speeds of 60 miles per hour for the collision with a nearby city that serves as home to about 500,000. Experts fear that the next great volcanic eruption of lava can be deadly for the surrounding villages.

Supervolcan Yellowstone

Supervolcan Yellowstone
The most violent eruption known occurred 2.1 million years ago. It ejected 2450 km³ of volcanic materials, creating at the same time the geological formation of Huckleberry Ridge Toba. A less important eruption that expelled 280 km³ of materials occurred 1.2 million years ago, giving rise to Island Park Caldera and the geological formation of Mesa Falls. About 640,000 years ago, a third volcanic eruption covered volcanic ash from rocks and other eruptive materials (1000 km³); all of the western United States, a part of the center of the country, and extended to the Pacific coast and to Mexico. After this cataclysm equivalent to 3000 times the eruption of Vesuvius in the year 79 or 1000 times more powerful than the eruption of Mount St Helens in 1980, it remained an immense caldera, of a size of 45 km by 85. The eruption gave rise to also to the geological formation called Lava Creek Tuff which is formed by tufa.
