20 Examples of Active Volcanoes (shocking images)

The volcanoes are geological structures that allow direct communication between the surface layer of the earth and the following, that is, the deepest points of the Earth crust: in particular, active volcanos they are the ones with a considerable probability of erupting at any moment. For example: Villarrica volcano, Cotopaxi volcano, Sangay volcano.

A geological structure of this type tends to appear more frequently in mountainous areas, and looks similar to that of the mountain, except for the fact that at its highest point it has a hole through which the material is expelled, a process known as eruption, which can be very destructive to the areas surrounding the volcano.

The geology has advanced in the investigation about volcanoes, so that today it is possible to define the state of a volcano and the probability that it will carry out this expulsion process.
In this sense, classification It comes to the conclusion that the eruption can only occur when there is an excess of magma at its base. As the formation of the magma base in volcanoes has a certain regularity, it is possible to affirm that if a volcano that tended to erupting every certain number of years, an amount many times greater than that passes without having any type of activity can to be

Extinct.

Active volcanoes and dormant volcanoes

In the event that there are no eruptions but there are certain activity logs It could be said that it will be a dormant volcano, and if the regularity of the eruptions makes one still possible, it will be said that it is an active volcano.

The eruption of the volcano is a process that can occur more or less abruptly and therefore can last a greater or lesser amount of time, in some cases lasting up to a year. Most of the built areas around a volcano are permanently on the alert for the potential for eruptions, despite the fact that there are not many ways to anticipate the imminent eruption of a volcano.

Volcanoes, as geological formation, appear on land but also in waters. With regard to surface volcanoes, the group of active volcanoes includes more or less 60 specimens around the world, almost half distributed between Central America, Southeast Asia and the India. Anyway, every continent has at least one volcano.

The following list will include the name and height above sea level, the location, the last eruption, and a photograph of a significant part of the world's active volcanoes.
