Scientists figured out why pyroclastic flow cheat friction and move rapidly. The findings could help scientists and the authorities to predict the movement of the heated volcanic materials and ...

Mixtures of hot volcanic rock and gas called pyroclastic flows travel so far by gliding on air, a new study suggests.

Volcanic 'avalanches' glide on air, boosting their deadly speed Pyroclastic flows are a leading cause of eruption-related deaths. Now, lab tests reveal the mind-bending reason they may rush down a ...

But a pyroclastic flow can transport thousands to millions of tons of volcanic material to regions dozens of miles from its source, bypassing barriers and surging up hilly terrain.

BALI’s largest volcano Mount Agung could send out a devastating flow of hot rock, ash and gas if it erupts. But what is a pyroclastic flow and how much damage could it do?

There are several ways pyroclastic flow can develop during an volcanic eruption. (AFP) Guatemala's Volcan de Fuego - Volcano of Fire - erupted spectacularly Sunday, shooting a plume of ash and gas ...

I think they were buried.” What is a pyroclastic flow? Pyroclastic flows are fast-moving currents of extremely hot gas and volcanic matter that pour down volcanic slopes at incredibly high speeds.

Scientists think they’ve figured out how pyroclastic flows, fast-moving bringers of death during volcanic events, can travel such incredible distances and ...

The image above shows the results of an avalanche of hot gases, ash, and rock known as a pyroclastic flow from Shiveluch volcano on the Kamchatka peninsula in Russia (from February 2011). When ...

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 ...

This river, or pyroclastic flow, may not be glowing orange like molten earth, but it is undeniably the most deadly part of the volcano.
