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

WATCH: A pyroclastic density current (PDC), locally known as "uson,” was recorded over the Mayon Volcano at 10:40 a.m. on Thursday, Feb. 26. Phivolcs said the flow lasted seven minutes, reaching some 2.5 kilometers from the summit crater and generating an over 1-kilometer-tall grayish to brownish ash cloud that drifted southwest. Alert Level 3 remains in effect over Mayon. | 🎥: Phivolcs/X via Fritz Dominique Madulid, INQUIRER.net trainee | INQUIRER.net

Mayon Volcano generated its largest pyroclastic density current at 10:35 a.m. on Monday, February 9, 2026. The PDC generated an extensive 1-kilometer-tall brownish ash plume that drifted to the southwest and brought ashfall over several barangays of Camalig and Guinobatan, Albay. Mayon remains under Alert Level 3. (📹: Phivolcs/ X) | ABS-CBN News

Pyroclastic density current or 'uson' from the Mayon Volcano on Tuesday (Jan. 6, 2026). The Philippine Institute of Volcanology and Seismology (Phivolcs) has raised Alert Level 3 (increasing tendency towards eruption) over Mayon. A total of 729 families or 2,889 individuals from different towns and cities inside the 6-km. permanent danger zone of Mayon Volcano are being monitored for possible evacuation. l via PNA Connie Calipay (Video courtesy of Edden Gayy) | SunStar Pampanga

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.
