The Department of Health (DoH) issued a public advisory Wednesday urging residents near Mayon Volcano to protect themselves against ashfall following a low-to-medium eruption earlier in the day.

The Philippine Institute of Volcanology and Seismology (Phivolcs) recorded the eruptive event at approximately 11:56 a.m.

Mayon Volcano remains under Alert Level 3, which was initially raised on 30 October following a moderate explosive eruption, indicating ongoing magmatic unrest.

“The DoH reminds the public in nearby areas to take precautions against the harmful effects of volcanic ash and coordinate immediately with local authorities if necessary,” the health department said.

To mitigate health risks associated with ash inhalation and exposure, health authorities advised residents to wear N95 face masks or cover their noses and mouths when outdoors.

Officials also urged community members to keep doors and windows closed and seal gaps with damp cloths to prevent ash intrusion.

Furthermore, residents are advised to maintain proper hydration, avoid entering the designated permanent danger zone around the volcano, and monitor official updates from local government units and Phivolcs.
