A breathtaking yet terrifying moment as Chile’s Calbuco Volcano unleashes a massive pyroclastic flow stretching over 7 km at sunset. The sky burns with fiery hues while ash clouds tower into the heavens, capturing the raw, unstoppable force of nature. A scene that reminds us how small we truly are before the power of the Earth. #Ethiopia #volcanoeruption #EpicEruption | Space Xplore

When a volcano erupts, pyroclastic flows are often the biggest danger to anyone nearby. These fast-flowing currents of rock, ash and hot gas are extremely difficult to study, so researchers created their own.

What is a pyroclastic flow and why is it so dangerous? | What If

Pyroclastic flow observed at Semeru Volcano This sped-up (x7) footage shows a pyroclastic flow descending the slopes of Semeru. These flows consist of hot ash, gas, and fragmented rock moving rapidly under gravity. Semeru remains one of Indonesia’s most active volcanoes and is continuously monitored.
