The volcano is the rupture on the crust of planetary mass such as earth, which allows hot lava, volcanic ash, and gases to escape from the magma chamber.
Volcanic activities have spread all over the world and can happen both on land and beneath the ocean.
Volcanic activities are especially active in convergent and divergent zones where tectonic plates move away or toward each other. Examples of volcanoes active in 2018 include the Hawaiian volcanic eruption and Oldonyo Lengai mountain in Tanzania.
A volcanic eruption can have both positive and negative effects on human activities and life in general.
