Hawaiian shield volcanoes are the Largest Volcano in the World. A volcano can be defined as an opening in the earth’s crust through which lava, volcanic ash, and gases escape. They are closely associated with plate tectonic activity. Liquid magma containing dissolved gases from the mantle or lower crust rises through the crust to the surface.

Largest Volcano in the World

The Hawaiian-Emperor Seamount chain, which spans 5,800 kilometers (3,600 mi) across the North Pacific Ocean, comprises more than 129 volcanoes, the youngest of which are the fifteen volcanoes that makeup Hawaii’s eight main islands.

Volcanology is the scientific study of volcanoes and their byproducts. Volcanoes can be found both on land and beneath the sea.

A shield volcano is a broad volcano with sloping sides created by the eruption of low-viscosity basaltic lava. Because it resembles a warrior’s shield lying on the ground, shield volcanoes get their name:

  • The magma from the vent slides down the slopes and builds up the size
  • The magma is high in temperature and very low in silica and gas content
  • The lava that erupted is runny and non-acidic
