Superheated avalanches of gas and rock have swept down the slopes of Mayon Volcano repeatedly in recent weeks, blanketing 87 barangays across the Philippine province of Albay in volcanic ash and ...

Superheated gas and volcanic debris roared down three gullies on Mayon Volcano in late May 2026, smothering at least 87 villages across Albay province under heavy ash and forcing thousands of ...

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 ...

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 ...

Indonesia's Mount Semeru erupted three times on Saturday morning, with the second eruption at 6.21 am triggering a ...

A pyroclastic flow (also known as a pyroclastic density current or a pyroclastic cloud) is a fast-moving current of hot gas and volcanic matter (collectively known as tephra) that flows along the ...

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 ...

An international team of scientists has uncovered the secrets of the speed of pyroclastic flow that brings death and destruction following a volcano eruption. A pyroclastic flow is an extremely hot ...

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 ...
