A Volcanic Eruption
Volcanic eruption is a natural phenomenon fou that occurs due to deposition of magma in the earth and flushed out by gas that has strong power. It is one of very powerful disasters. Almost all of the volcanic activities relate to the zone of active seismicity because it is directly connected with the plate boundary of the earth.
The volcanic eruption begins with the activity at plate boundary of the earth that sustains a significant change in pressure and temperature. So, it can make the rock material around it melt which we usually called as incandescent liquid or Magma Magma formed through extreme hot temperature in the earth bowels. At a relative depth, a very high temperature can make the entire material in the earth bowels melt.
When these materials melt, it produces gas that will mix with the magma Magma that will be released by the volcanic eruption formed at a depth of approximately 60 to 160 kilometres below the earth's surface. Then the magma that contains gas will be under the pressure of solid rocks that are around the crater. This pressure causes the magma to erupt and move out towards the earth's surface.
The magma and the gas burst at the same time and create a hole which is called the main hole. Most of the magma and other volcanic materials spurt through this main hole. After the bursts stop, the crater that resembles a bowl is usually formed at the top of the volcano Meanwhile, the main hole is in the bottom of the crater
