Eerie Sound from Approaching Pyroclastic Flow at Semeru Volcano, Indonesia, (Nov 19, 2025) "On 19 November 2025, Indonesia’s Mount Semeru produced a large and dangerous pyroclastic flow, sending searing clouds of ash, gas, and rock many kilometers down its slopes. This video captures the scale of the event from a safe vantage point. According to Indonesia’s Geological Agency (PVMBG), today’s eruption generated pyroclastic density currents traveling 7–8.5 km from the summit, accompanied by ash co

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
