The Blue Planet’s Volcanoes

Come & explore the Blue Planets volcanoes with us and find out just what happens when a sleeping volcano erupts.

The earth’s volcanoes occur because its crust is broken into 17 major, rigid tectonic plates, that float on a hotter softer layer in its mantle.

Erupting volcanoes can pose many hazards, not only in the immediate vicinity of the eruption. One such hazard is that volcanic ash can be a threat to aircraft, in particular those with jet engines where ash particles can be melted by the high operating temperature; the melted particles then adhere to the turbine blades and alter their shape, disrupting the operation of the turbine.

Large eruptions can affect temperature as ash and droplets of sulfuric acid obscure the sun and cool the Earth’s lower atmosphere; however, they also absorb heat radiated from the Earth, thereby warming the upper atmosphere (or stratosphere).

Historically, volcanic winters have caused catastrophic famines.
