admin A volcano is a landform that results from magma (molten rock within the earth) erupting at the surface. The size and shape of a volcano reflect how often it erupts, the size and type of eruptions, and the composition of the magma it produces.
During the past 10,000 years, there are around 1510 active volcanoes in the world. We currently know of 80 or more which are under the oceans.
At present, there are about 600 volcanoes that have had known eruptions during recorded history, while about 50-70 volcanoes are active (erupting) each year.
