A pyroclastic flow burst from Mount Etna’s summit on 2 June 2025 and raced down the volcano’s western flank while a 6.5-kilometer ash plume climbed above the crater, forcing tourists on the upper ...

Roughly 3,000 residents have left their homes near Mayon Volcano in the Philippines after pyroclastic flows began sliding ...

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) 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 ...

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 ...

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 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 ...

When magma bubbles up toward Earth's surface and meets groundwater, steam pressure builds, sometimes bursting into eruptions that spew currents of hot ash, potentially burning and asphyxiating people ...
