Image description
The image shows an erupting volcano, viewed from the front or from one side, illustrated at its top.
The volcano is a geological structure in the form of a cone, made up of solidified debris, that is layers of lava and ashes, from a previous eruption. The volcano has narrower walls as it climbs to the top, called the summit. Its center is a round, deep hole called the crater. At the base of the crater is a crack in the Earth’s crust, called the vent, through which extremely hot and viscous lava, gas and ash emerges or erupts, from a fissure near the earth’s crust. The magma chamber is like a bag filled with magma, that is, gases and molten rocks gushing from the mantle, which penetrate through fissure vents.
Under the pressure of a heavier tectonic plate moving on top of a lighter one, the latter one subsides and eventually splits, right at the point where it is thinner. Thus, cracks or fissures appear, called a rift. This rifting allows the magma and gases to come to the surface. Upon contact with the surface of the crust, the magma becomes lava, rendered here by a dotted texture, with the bottom edge wavy, located at the upper edge of the volcano, flowing around it.
The gases are spewed first, in case of an eruption, along with the volcanic ash and the pieces detached from the volcano called tephra, highlighted here in the center, above the volcanic crater, marked embossed. After the lava starts to flow, gases and ash still continue to come out like clouds of smoke.
Under the layer of lava flowing, the volcano conical mountain can be seen, marked embossed, at the base of the image.
