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 ...

The eruption of the Fuego volcano—or volcano of fire—in Guatemala on Sunday and the flows that followed have killed more than 60 people so far, according to authorities. The volcano is one of the most ...

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 ...

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 ...

Figure 1: Map of the Peach Spring Tuff and locally derived lithic clasts. Figure 4: Size of the blocks in the Peach Spring Tuff and their source area at three locations in Kane Wash in California. To ...

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 ...

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 ...

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 ...

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 ...
