According to Roman mythology , Vulcan He was the god of fire and metals. Married to Venus and father of Jupiter and Juno , Vulcano was the creator of weapons and armor for heroes.
The word volcano It 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. The volcanoes are openings found in mountains or on earth; Every certain period of time, they expel lava, gases, ashes and smoke.
Among the most important and famous volcanoes in the world is, for example, the Kilimanjaro that is located in Tanzania. Its more than 5,000 meters high make it one of the tallest on the planet and is characterized by three craters.
Nor can we forget other equally significant volcanoes such as the Krakatoa volcano, located in Indonesia; Teide volcano, located on the island of Tenerife; the Popocatepetl volcano in Mexico or Vesuvius, in Italy. In Naples it is where the latter, who has been the cause of the burial of the cities of Pompeii and Herculaneum in 79 AD, is among its most significant events.
The eruption , as this expulsion process is known, occurs when the 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, underwater, fisural, Pelean, Vesuvian or mixed.
It is called chimney to the conduit that communicates the magmatic chamber of depth with the earth's surface. 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 talk about dormant volcanoes . On the other hand, volcanoes that were active not too long ago or that currently are still eruptive, are called active volcanos .
And all this without forgetting that there are also those known as sleeping volcanoes that are those that are characterized by the fact that they maintain certain signs of volcanic activity. In particular, all those who have not erupted for centuries are called that.
A supervolcano It is a type of volcano that is characterized by its voluminous eruptions, with strong explosions and a large volume of expelled magma. These supervolcanoes have the ability to modify the climate for years and to alter the surrounding landscape in a radical way.
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 "being on a volcano" with which what is done is to determine that a person in question is living a dangerous situation without knowing it.
