Insane footage of a volcano explosion. | This is Happening

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

You can’t outrun them, you can’t hide from them, you can’t stop them! An avalanche of scorching volcanic ash and lava, known as a pyroclastic flow, cascades down the side of Sinabung volcano, Indonesia, in June 2015. This flow was the largest I ever saw at the volcano as it moved over previously untouched trees and farmland. #volcano #forcesofnature #planetearth | Earth Uncut TV with James Reynolds

WATCH: Time-lapse footage of a pyroclastic density current (PDC) or "uson" at Mayon Volcano that began at 10:50 AM today, 26 February 2026, and had a flow duration of four (4) minutes before coming to rest some 2.5 kilometers of the summit crater. The PDC descended the Mi-isi Gully (south-southwest) and generated a grayish to brownish >1 kilometer-tall ash cloud that drifted southwest. Alert Level 3 prevails over Mayon Volcano and entry into the 6-km Permanent Danger Zone should be prohibited. S
