Volcanoes are geological formations on the earth's crust. From them, magma breaks out onto the earth's surface, forming lava, volcanic gases, as well as mixtures of gas, stones and volcanic ash. Such mixtures are called pyroclastic flows.
It should be noted that the word "volcano" came from Ancient Rome, where the god of fire was called by this name.
A lot of interesting things are known about these natural phenomena, and in the article you can find some real facts about them, including information about volcanic bombs (see photo in the article).
General information
The lands that stretch at the foot of volcanoes are quite fertile. And all this is due to the fact that the eruptions produced by the vent of the volcano saturate the soil of the surroundings with a large amount of minerals and nutrients. Even in the case of a dormant volcano, the wind blowing around it carries substances important for the soil in different directions. That is why people settle even on the slopes of the mountains, not paying attention to the emerging tremors from the bowels.
And that's itit's completely useless. Many people know about the sad fate of the inhabitants of Pompeii, who died during the monstrous eruption of Vesuvius, which occurred about 2000 years ago. This tragedy could have been avoided if attention had been paid to the increasing frequency of earthquakes in this region.
What are volcanic bombs called?
This is a piece or piece of lava ejected from a vent during a volcanic eruption. It is in a plastic or liquid state, which received a specific form during squeezing and solidification during flight through the air.
All solid products of the eruption are usually ejected from the bowels in the form of ash and various pieces. Small fragments are called lapilli, while larger fragments are called volcanic bombs.
Description
The shape of these fragments can be different. It all depends on the composition, flight conditions and viscosity of the lava. Due to the rotation of the ball in flight, it can take on a spindle-shaped or twisted shape.
Due to their plastic consistency, they often change shape during flight or when they hit the ground. Liquid lavas, which do not have time to cool in the air, in the process of hitting the ground acquire the shape of a shortbread, and low-viscosity mixtures (bas alt) acquire a pear-shaped shape due to rotation in flight. More viscous masses become round in shape.
As for the internal contents of a volcanic bomb, it can be bubbly or porous. outdoorthe crust becomes glassy and dense due to rapid cooling in air.
In diameter, such a bomb can reach 7 meters, but in most cases it does not exceed a few centimeters. At the time of the explosion of the volcano, bombs sometimes fly out of the crater, having a mass of up to several tons. They can be found on the slopes of any volcano.
Recent incident
Not so long ago, 23 people were injured in Hawaii as a result of a volcanic bomb hitting a boat with tourists. Such a horrifying incident happened near the Kilauea volcano, the eruption of which began in early May.
Reports say that a ship owned by Lava Ocean Tours was damaged by volcanic lava. It happened at six o'clock in the morning near the Kilauea volcano. It is not known exactly how far the ship was, but it received quite a lot of damage: the ship's roof was broken, the skin was melted and the railing was damaged.
In closing
Fire-breathing mountains appear above the places of collision of lithospheric plates. This happens in the weakest places of the earth's crust, through which the planet from its bowels throws red-hot magma, volcanic bombs, combustible gases and other hot material onto the earth's surface. All these masses form most of the mountains.
The word "volcano" is of Latin origin. As noted above, in ancient Rome this was the name of the god of fire. An interesting fact is that Mount Etna was the first to receive such a name. According to residentsthis area, it was there that the forge of Vulcan was located.
