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

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.

LOOK: Time-lapse footage of Mayon Volcano’s summit shows pyroclastic density currents (PDCs) generated by lava dome collapse at 1:16 PM and 4:09 PM, according to PHIVOLCS. The agency also recorded a total of 16 PDC events between 12:26 PM and 4:30 PM on January 7, 2026, producing grayish to brownish ash clouds that rose up to 200 meters drifting east-northeast. Alert Level 3 remains while entry into the 6km Permanent Danger Zone is prohibited. Courtesy: PHIVOLCS/Facebook | GMA News
