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 ...

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 ...

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, ...

BUFFALO, N.Y. -- Technologies ranging from mathematical modeling, geologic simulation and geographic information science to scientific computing and virtual reality are being combined by University at ...

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 ...

On Sunday, Guatemala’s Volcán de Fuego — “Volcano of Fire” — erupted violently, spewing ash nearly four miles into the air and burying villages under an avalanche-like phenomenon called a pyroclastic ...

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 ...

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 ...

Pyroclastic flows are some of the most fearsome hazards posed by erupting volcanoes. These avalanches of superheated ash, gas, and rock are responsible for some of the most famous volcanic disasters ...

Imagine a 1,300-degree avalanche of rocks, gas, ash and debris roaring toward you at speeds of up to 50 mph. That's exactly what happened to dozens of Guatemalans on Sunday, when the nation's infamous ...

While the town around him was engulfed by searing pyroclastic flows, one man achieved the impossible from a prison cell with a single ventilation shaft. Here’s how he did it. While humans have adapted ...
