Albay province, Philippines – Inside the gymnasium-turned-shelter in Daraga, families sleep on cardboard mats between folding ...

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 ...

One of the leading killers during explosive volcanic eruptions is a family of superheated gas, ash, and debris known as pyroclastic density currents. These tumbling, turbulent paroxysms rush downslope ...

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 ...

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 ...

AS the Department of Science and Technology-Philippine Institute of Volcanology and Seismology (DOST-Phivolcs) assesses a possible extension of the permanent danger zone around Mayon Volcano, where ...

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 ...

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 ...
