Volcano facts

Ancient Greeks and Romans believed that volcanoes were under the control of gods. The name volcano even comes from the name of the Roman god of fire, Vulcan.

The ring of fire is home to 90% of earths volcanoes

About 1,900 volcanoes are active today or known to have been active in historical times. Almost 90 percent are in the Ring of Fire, a band of volcanoes circling the edges of the Pacific Ocean.

350 million, or 1 in 20 people live within the danger range of an active volcano.

Maleo birds use the heat from volcanoes to incubate their eggs

Maleo birds use the heat from volcanoes to help hatch their eggs. They bury the eggs in the soil near the volcanoes, then when the chicks hatch they claw their way up to the surface.

The worlds largest active volcano is Mauna Loa in Hawaii, standing at 4,169m.

In 1883 Krakatau in South east Asia erupted, releasing 200 megatons of energy, the equivalent of 15,000 nuclear bombs. This generated the loudest sound reported in history.

Volcanic eruptions can send ash high into the air, over 30km (17 miles) above the Earth’s surface.

The object with the most volcanic activity in our solar system is Io, one of Jupiter’s moons. Covered in volcanoes, its surface is constantly changing due to the large amount of volcanic activity.
