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 ...

Satellite photos have captured a glowing "river of fire" flowing down the flanks of Mount Etna during an explosive outburst that also unleashed a giant plume of ash, smoke and volcanic gases high ...

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 ...

Volcanologist Professor Chris Jackson discovers evidence of the deadly pyroclastic flow. Volcanologist Professor Chris Jackson reveals the power of the deadly pyroclastic flow that had swept through ...

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 ...

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 ...

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, ...

An explosion on the slopes of Stromboli sent an avalanche of pyroclastic flow rushing down the side of the Italian volcano on Monday (Nov. 16). The stronger-than-usual explosion was captured on ...

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 ...

The Mayon Volcano is exhibiting signs of increasing unrest, with bright red magma and glowing pyroclastic density currents ...

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 ...
