Alert Level 3 was raised over Mayon Volcano in Albay due to a “high level” of unrest, with pyroclastic density currents (PDCs) recorded. But what exactly are PDCs? The Philippine Institute of ...

A pyroclastic density current tumbles anew toward the foot of the restive Mayon Volcano on May 8, 2026. The volcano has been restive for five months, forcing thousands of Albayanos into temporary ...

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 ...

The discovery of the driving force behind the world's deadliest volcanic events could help improve forecasting of their devastating effects, new research suggests. The findings reveal the mechanism ...

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 ...

Lava effusion with collapse-fed pyroclastic density currents (PDCs) was observed at Mayon Volcano on Sunday night as the ...

MANILA, Philippines — Ashfall hit several areas in Albay yesterday after Mayon Volcano emitted a lava flow collapse-fed pyroclastic density currents (PDCs) or uson, according to the Philippine ...

Thick deposits (~4 m) of the Tierra Blanca Joven pyroclastic density currents at a site located 30 km west of the vent. These fast flows of hot particles and gas decimated everything within 40 km of ...
