When a volcano erupts, pyroclastic flows are often the biggest danger to people nearby. These fast currents of rocks, ash and extremely hot gases are extremely difficult to study. New Zealand researchers have therefore created theirs. By closely studying the pyroclastic flows in their specially constructed laboratory, they have identified a very thin layer of gas that helps explain how this volcanic phenomenon moves so fast and can go so far.
