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 ...

Avalanches of ash, gas and rock that cascade downhill during volcanic eruptions may be even more dangerous than scientists had realized. Pulses of high pressure form within these slides, known as ...

Unlike a regular camera view, the thermal perspective makes the temperature of the flow far more visible, highlighting the ...

On Sunday, Guatemala's Volcán de Fuego -- "Volcano of Fire" -- erupted violently, spewing ash nearly four miles into the air and burying villages under an avalanche-like phenomenon called a ...

A superheated torrent of gas, rock, and volcanic debris tore 4 kilometers down Mayon volcano’s Mi-isi Gully in early June 2026, marking the longest pyroclastic density current recorded during the ...

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 ...

Pyroclastic surges are lethal hazards from volcanoes that exhibit enormous destructiveness through large dynamic pressures of 100–102 kilopascal inside flows that are capable of obliterating ...
