Volcano Eruption caused by Nature

 Nature’s Hazardous Effect is a natural phenomenon that might have a negative effect on humans and other animals, or the environment.

 A volcano is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface.

Volcanoes have existed for a long time on Earth, likely causing disasters such as the Permian mass extinction about 250 million years ago, the greatest mass extinction in Earth’s history, according to a 2015 paper. Volcanoes can and have existed on other worlds as well: although volcanoes on the moon and Mars have long been dormant, volcanoes are still very active on Jupiter’s moon Io. Researchers are currently striving to find ways to predict when volcanic eruptions might happen on Earth by analyzing clues such as crystals and gases linked with volcanoes.

Origin of volcano (Formation)

Earth’s crust is 3 to 37 miles (5 to 60 kilometers) thick, according to the U.S. Geological Survey. It is broken up into seven major and 152 smaller pieces called tectonic plates, according to a 2016 paper by Christopher Harrison at the University of Miami. These plates float on a layer of magma semi-liquid rock and dissolved gases. At the boundaries of these plates where they move past, are pushed under, or move away from each other magma, which is lighter than the surrounding solid rock, is often able to force its way up through cracks and fissures. Magma can explode from the vent, or it can flow out of the volcano like an overflowing cup. Magma that has erupted is called lava.

Lava flows are almost always too slow to run over people, but they can certainly run over houses, roads, and any other structures. Pyroclastic flows are mixtures of hot gas and ash, and they travel very quickly down the slopes of volcanoes. They are so hot and choking that if you are caught in one it will kill you.
