Find out why volcanoes erupt

Tungurahua volcano

All the Volcanic eruptions They are one of the greatest spectacles that nature offers us. Striking, shocking, and sometimes dangerous: they have everything for humanity to fear ... or on the contrary want to get as close as possible to them to contemplate their beauty. A beauty of fire, ash, and sometimes even lightning.

But have you ever wondered why volcanoes erupt?

Well the explanation is really simple: Inside the volcano there is liquid rock with a very, very high temperature -between 700 and 1500 degrees Celsius-, which looks for a way out. But of course, how does it erupt and why? That is, why does a volcano "wake up"?

It turns out that gases and molten rock accumulate inside it, causing the magma, which is several kilometers from the surface, to rise due to pressure. As it does so, it melts the rocks in its path, adding more pressure. Finally, when it "can't take any more", it is when it explodes in a more or less violent way depending on the characteristics of the volcano, expelling ash and dust into the atmosphere, while leaving its particular trail also in the towns or cities that are around it. .

Arenal Volcano

As we said, sometimes lightning appears in the sky during a volcanic eruption. Currently there is not a single possible explanation for this phenomenon, but two, which are:

  • The hot air that emerges from the volcano, encountering a cold atmosphere, produces them.
  • Or it may be due to the fact that all the material that emerges from the volcano has an electrical charge capable of generating lightning.

Volcanic eruptions are true wonders: it is one more example of the power that nature has, and that we can see live and direct from many points, such as from Sicily (Etna volcano), or Japan (Mount Aso).
