Pyroclastic flow can travel down a mountain at speeds from 60 miles per hour to more than 200 miles per hour, which makes running away impossible if you are too close at the time of eruption.

Scientists think they’ve figured out how pyroclastic flows, fast-moving bringers of death during volcanic events, can travel such incredible distances and speeds despite the friction between the ...

Mount Etna, the volcano that towers over eastern Sicily, has again captivated the world with a spectacular show, spewing smoke and high into the sky. But the defining event of Monday's eruption was ...

The emplacement of small-volume ( less than 0,1km3) pyroclastic flow is strongly controlled by topography, according to a new study by researchers of the Institute of Earth Sciences Jaume Almera ...

Evidence suggests that the residents of the ancient town of Herculaneum were incinerated by a "pyroclastic flow" - a phenomenon that could strike modern-day Naples should Vesuvius erupt again.

The researchers said this could not have happened if the individual was heated solely by the pyroclastic flows – avalanches containing lava pieces, ash and hot gases – which buried Pompeii and ...

April 9 (UPI) --Large volcanic eruptions can trigger the formation of superheated gas-and-ash clouds. These pyroclastic density currents, or pyroclastic flows, are the most lethal volcanic threat ...
