The characteristics of actively erupting volcanoes are:
1. Increased heat flow from the volcano
2. Steam eruption from the volcanic crater
3. Increased gas flow from a volcano
At the point when magma is more blazing than neighboring magma, it is supposed to be in a "hotspot" on the planet. This could occur over a mantle tuft or under the earth's covering, which is its rough external layer. Boundless volcanic movement and rock-hull liquefying are both welcomed on by the magma crest. On Earth, a mantle crest is situated over a locale known as a hot spot. A mantle tuft is a locale of more blazing magma than the encompassing magma under the World's hull, which is comprised of hard shakes.
