Pyroclastic flows: The secret of their deadly speed

by

When a volcano erupts, pyroclastic flows are often the biggest danger to anyone nearby. These fast-flowing currents of rock, ash and extremely hot gas are extremely difficult to study, so researchers in New Zealand created their own. By closely studying pyroclastic flows in their specially-made lab, they identified a very thin layer of gas that helps explain how this volcanic phenomenon moves so fast and can travel so far.

In This Story: Volcano

A volcano is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface. On Earth, volcanoes are most often found where tectonic plates are diverging or converging, and most are found underwater.
