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

PYROCLASTIC FLOW A pyroclastic flow is a fast-moving current of extremely hot gas, volcanic ash, and rock fragments that rushes down the slopes of a volcano during explosive eruptions. These flows can reach speeds of over 320 km/h and temperatures exceeding 1,000 °C, making them one of the most dangerous volcanic hazards. Unlike lava flows, pyroclastic flows can travel great distances, destroy everything in their path, and cause widespread devastation due to their speed, heat, and suffocating as

🌋🔥 Nature’s Deadliest Avalanche: The Pyroclastic Flow 🔥🌋 An unstoppable river of ash, gas, and rock — hotter than 1,000°C and faster than a car — racing down a volcano, erasing everything in its path. This is the terrifying force that buried Pompeii, and it’s still a threat today. 😳🌪️ Would you survive if one came your way? #VolcanoFacts #ExtremeEarth #PyroclasticFlow #ScienceExplained #BreakingNature ⚠️ Disclaimer: This reel may include AI-generated visuals for educational purposes.

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.
