Volcanic eruption in Suwa-no-Sejima, Japan, what's the difference between an active volcano and an extinct volcano?

Volcanic eruption in Japan, which follows the recent Hawaiian eruption in the world of volcanic eruptions. There is a difference between an active volcano and an extinct volcano. Volcanoes are inanimate and the use of these two words to describe volcanoes is more realistic and close to the state of the volcano. In general, an active volcano is a volcano that is very active and has the potential to erupt, while an extinct volcano is a dormant volcano that has a low or almost no potential to erupt. A volcanic eruption is the eruption of magma from the earth's crust out of the ground. The magma that erupts is a very hot liquid, and the temperature of this liquid makes it capable of swallowing almost anything on the surface of the earth. So when a volcano erupts, any area where the magma flows through will essentially be in ruins.

An eruption is also accompanied by the release of large quantities of toxic gases, which have an impact on the global environment. When a volcano erupts, a large amount of sulfur dioxide gas will come out of the ground, resulting in serious pollution of the atmosphere. The rotten egg smell that we usually smell around volcanoes and hot springs is the smell of sulfur and its compounds. Although sulfur dioxide is a colorless gas, it is highly toxic and can become sulfuric acid if combined with rainwater. Our common acid rain is because some of the rain and sulfur dioxide and sulfuric acid combination, the formation of acid rain.

If you live near a volcano, you need to be aware of the volcano's condition and learn how to escape. This is because when a volcano erupts it is unpredictable, and although it is possible to know that the volcano may erupt in the near future, it is not possible to know exactly when the volcano will erupt. Because of this, we must be familiar with the relevant escape techniques in our daily lives, so as not to be at a loss when the danger arrives.

Human beings are very small, in the face of nature, we should go to adapt to the changing environment, to learn the relevant escape skills is very important.
