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

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 ...

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 ...

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 ...
