Pyroclastic flows: the secret of its deadly speed.



When a volcano erupts, pyroclastic flows are often the greatest danger to nearby people. These rapid currents of rock, ash and extremely hot gas are extremely difficult to study, so researchers in New Zealand created their own. By carefully studying the pyroclastic flows in their special manufacturing laboratory, they identified a very thin layer of gas that helps explain how this volcanic phenomenon moves so fast and can travel so far.
