Our world is filled with natural wonders. We know that when God created the Earth, he made sure that nature was at its best. However, beauty is not the only thing that nature can offer. Just like any other thing, it too carries an ugly side. One of the known characters of nature is none other than the volcanoes. We can see thousands of volcanoes plotted in different places here on earth. Most of them are located along the Pacific Ring of Fire. Volcanoes are described as land structures that form an opening or rupture on the Earth’s crust or surface. This opening will be the passage way for magma, ash, and other volcanic gasses to pass through from below. When this situation occurs, catastrophe is already at hand. However, let us try to discuss first how does volcanoes erupt.
Volcanoes do erupt due to the increase in pressure that is found beneath the Earth’s crust. This pressure along with extreme temperatures causes the rocks beneath the crust to melt into a semi liquid condition. This melted rocks and earth is commonly known as magma. This magma will then try to escape from below since the density above is lesser. This causes a volcano to eventually erupt.
As soon as the pressure is too high, the magma will be pushed above and will try to seep in through the Earth’s crust, which will find its way to some of the underground magma chambers. As soon as these chambers are filled, the pressure inside will also intensify. The gasses coming from the magma will also be responsible for the increasing pressure. These gasses can either push the volcano into eruption or not. Another factor that can determine whether a volcano will or will not erupt is the presence of water. If there is too much water underground, the water will eventually heat up, thus causing an increase in the pressure. If this occurs, the volcano will most likely release the gas into explosion.
A single explosion of a volcano can actually cause the devastation or the wipe out of an entire city. It is even powerful enough to change the seasons and weathers of a large portion of the Earth. Its intensity in eruption can be measured using the VEI or Volcanic Explosivity Index. This rates the strength or the power of a certain explosion from 0, being the lightest, to 8, being the most intense. This is also based on the volume of ash ejected.
These are some of the reasons and descriptions on how does a volcano erupt. This clearly shows that nature should never be pushed to its limit.
