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, ...

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 ...

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 ...

Semeru volcano — the tallest volcano on Java at 3,676 meters — erupted on the afternoon of November 19, 2025, with pyroclastic flows racing at high speed more than 8.5 kilometers down its slopes, as ...

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 ...

MANILA, Philippines — A surge in pyroclastic density currents has been detected at Mayon Volcano in Albay in the past 24 hours, although these do not indicate escalation to a stronger eruptive phase, ...

Guatemala’s Volcan de Fuego — Volcano of Fire — erupted spectacularly Sunday, shooting a plume of ash and gas nearly 6 miles into the sky and spreading ash and debris across towns and farms more than ...

MANILA, Philippines — Since showing increased activity earlier this year, Mayon Volcano generated its "largest" pyroclastic density current so far, with an ash plume reaching up to 1,000 meters on ...

Volcanoes are increasingly recognized as agents and recorders of global climate variability, although deciphering the linkages between planetary climate and volcanism is still in its infancy. The ...

Mount Sinabung in Indonesia has been exploding with ash and debris since early June, now in its fifth year of activity since the long-dormant volcano came back online after hundreds of years of ...
