A pyroclastic flow burst from Mount Etna’s summit on 2 June 2025 and raced down the volcano’s western flank while a ...

A group of scientists from Te Kunenga ki Pūrehuroa Massey University recently co-published an article on the hazard impacts of pyroclastic density currents. Pyroclastic density currents are ...

Pyroclastic density currents (PDCs) are high-energy, ground-hugging flows of hot gas and fragmented volcanic material that pose one of the greatest lethal volcanic hazards. Their dynamics are governed ...

Pyroclastic surges are lethal hazards from volcanoes that exhibit enormous destructiveness through large dynamic pressures of 10 0-10 2 kilopascal inside flows that are capable of obliterating ...

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 ...

Geologists have determined why — unlike in the neighbouring town of Pompeii — the inhabitants of the ancient Roman town of Herculaneum were not well-preserved by the eruption of the volcano Vesuvius ...
