What Does volcano Mean
According to Roman mythology , Vulcan was the god of fire and metals. Married to Venus and father of Jupiter and Juno , Vulcan was the creator of weapons and armor for heroes.
The word volcano comes from Vulcano. It is a conduit that establishes direct communication between the earth's surface and the deep levels of the earth's crust. Volcanoes are openings found in mountains or on land; every certain period of time, they expel lava, gases, ash and smoke.
Among the most important and famous volcanoes in the world is, for example, that of Kilimanjaro which is located in Tanzania. Its more than 5,000 meters high make it one of the highest on the planet and is characterized by being made up of three craters.
Likewise, we cannot forget other equally significant volcanoes such as the Krakatoa volcano, located in Indonesia; the Teide volcano, located on the island of Tenerife; the Popocatepetl volcano in Mexico or Vesuvius in Italy. In Naples is where the latter is found, which has among its most significant events having been the cause of the burial of the cities of Pompeii and Herculaneum in 79 AD.
The eruption , as this expulsion process is known, occurs when magma (a mixture of molten rock, gases and other components) that is under pressure begins to rise.
Among the main types of volcanic eruptions, taking into account criteria such as their viscosity or temperature, are Hawaiian, Vulcan, Surtseyan, submarine, fissure, Peleano, Vesubian or mixed.
The chimney is called the conduit that communicates the deep magmatic chamber with the earth's surface. The lava erupts through the central chimney of the volcano, which can also present other formations known as parasitic cones and even some that only expel gases and are called fumaroles .
When there is no record of the eruptive activity of a volcano, specialists speak of dormant volcanoes . On the other hand, volcanoes that were active not too long ago or that currently continue with eruptive activity are called active volcanoes .
And all this without forgetting that there are also those known as dormant volcanoes, which are those that are characterized by the fact that they maintain certain signs of volcanic activity. Specifically, those who have not made an eruption for centuries are so called.
A supervolcano is a type of volcano that is characterized by its voluminous eruptions, with strong explosions and a large volume of ejected magma. These supervolcanoes have the ability to modify the climate for years and to radically alter the landscape that surrounds them.
Finally, we cannot ignore the fact that the term in question is also part of some expressions that we use in colloquial language. An example of them is the adverbial phrase "to be on a volcano" with which what is done is to determine that a person in question is living a dangerous situation without knowing it.
