Volcanologist Professor Chris Jackson discovers evidence of the deadly pyroclastic flow. Volcanologist Professor Chris Jackson reveals the power of the deadly pyroclastic flow that had swept through ...

One of the leading killers during explosive volcanic eruptions is a family of superheated gas, ash, and debris known as pyroclastic density currents. These tumbling, turbulent paroxysms rush downslope ...

After an eruption, DIY cushions of gas help searing torrents of gas, ash, and rock spread miles from their source within a matter of minutes. Pyroclastic flows contain a deadly combination of hot rock ...

Pyroclastic density currents (PDCs) represent some of the most formidable and complex volcanic phenomena, characterised by a turbulent mixture of solid particles and gases that surge down slopes at ...

Guatemala’s Volcan de Fuego — Volcano of Fire — erupted spectacularly Sunday, shooting a plume of ash and gas nearly 6 miles into the sky and spreading ash and debris across towns and farms more than ...

A new study sheds light on what happens when a supervolcano erupts, providing insight on how rivers of hot ash and gas called pyroclastic flows manage to travel huge distances of over 100 miles during ...
