Pyroclastic density currents (PDCs) represent some of the most formidable and complex volcanic phenomena, characterised by a turbulent mixture of solid particles and gases that surge down slopes at ...

Learning how these hard-to-predict and hard-to-escape currents work is paramount to protecting the communities that live in their potential paths. For instance, many pyroclastic density currents ...

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 ...

Thermal camera footage also released by PHIVOLCS showed pyroclastic density currents — fast-moving flows of hot gas and volcanic material — cascading down the southern slopes of the volcano. The ...
