One of the first natural phenomenons to shape the world was volcanos. 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. Volcanos occur when magma rises through cracks or weaknesses in the Earth’s crust. Then, pressure builds up inside the Earth. When this pressure is released, eg as a result of plate movement, magma explodes to the surface causing a volcanic eruption. Volcanoes erupt because of density and pressure.
The lower density of the magma relative to the surrounding rocks causes it to rise . The lava from the eruption cools to form new crust. Over time, after several eruptions, the rock builds up and a volcano forms. Sixty percent of all active volcanoes occur at the boundaries between tectonic plates. Most volcanoes are found along a belt, called the “Ring of Fire” that encircles the Pacific Ocean. Some volcanoes, like those that form the Hawaiian Islands, occur in the interior of plates at areas called “hot spots.”The natural phenomenon known as volcanoes can damage our environment when they erupt. When volcanoes erupt, they emit a mixture of gases and particles into the air.
Some of them, such as ash and sulphur dioxide, have a cooling effect, because they (or the substances they cause) reflect sunlight away from the earth. Others, such as CO2, cause warming by adding to the the greenhouse effect. Livestock and other mammals have been killed by lava flows, pyroclastic flows, tephra falls, atmospheric effects, and gases. Volcanoes don’t necessarily kill people its the factors and impacts after the volcanoes erupt. If the ashfall is really heavy it can make it impossible to breathe.
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.You can prepare for Volcanic eruptions by not living by volcanoes. If you do live by a volcano you can evacuate the area. There is no actual way to recover from volcanic eruption.
The only advice the internet has, is to listen to your local radio stations for civil defence advice and follow instructions. Stay indoors and away from volcanic ashfall areas as much as possible. Follow the evacuation order issued by authorities and evacuate immediately from the volcano area to avoid flying debris, hot gases, lateral blast and lava flow. In conclusion, Volcanoes are cool but can be dangerous when they erupt.
Fun fact! The last volcano article was written two days ago and it stated “Mount Agung could remain on brink of major eruption for weeks as ash continues to spew, warn volcanologists. A volcano in Indonesia could remain on the brink of a major eruption for weeks as it continues to spew ash across the island of Bali, volcanologists have warned.” (Independent, Samuel Osborne). Well i think i’m done. Peace Out man.
I am moving to Hawaii by the way. So Aloha.
