Scientists have discovered that the scorching material spewed from a volcano during eruptions generates a layer of air between it and the ground, allowing it to surf along at extreme speeds, ...

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 flows are a common and devastating result of some volcanic eruptions. They are fast-moving fluidized bodies of hot gas, ash and rock (collectively known as tephra) which can travel away ...

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 ...

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 ...

When Guatemala’s Volcán de Fuego erupted in June 2018, it sent a billowing hot cloud of gas, ash and rock careening down the slope of the mountain. In the many smartphone videos of the eruption, the ...

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 ...

Dumping literal tons of hot volcanic material down a lab flume may finally have revealed how searing mixtures of hot gas and rock travel so far from volcanic eruptions. These pyroclastic flows can ...
