• Mayon volcano eruption sends ash clouds and pyroclastic flow across Eastern Philippines
• Alert remains in force as authorities restrict access and monitor possible escalation

Mayon Volcano in the Philippines erupted on Saturday, unleashing a fast-moving pyroclastic flow and a dense ash cloud, disrupting transport and prompting official warnings.

Authorities said the pyroclastic density current, locally known as “uson,” rushed down the volcano’s southwestern slopes.

Large plumes of black smoke and ash rose into the sky, reducing visibility and forcing several vehicles to temporarily stop along the Camalig bypass road.

Officials warned that these pyroclastic flows, made of hot gases, ash, and volcanic debris, can travel rapidly and pose a serious threat to nearby communities.

Mayon, one of the country’s most active volcanoes, remains under close surveillance as authorities assess ongoing activity and the risk of further eruptions.

Residents in surrounding areas have been urged to stay alert for additional ashfall and possible evacuations if conditions worsen.

The alert level remains at Level 3, with entry strictly prohibited within the 6-kilometre permanent danger zone.
