PHIVOLCS said Alert Level 3 (Intensified Unrest/Magmatic Unrest) remains in effect at Mayon Volcano.

This is because the volcano continues to pose hazards such as:

• rockfalls or landslides or avalanches;
• ballistic fragments;
• lava flows and lava fountaining;
• PDCs;
• moderate-sized explosions; and
• lahars during heavy and prolonged rainfall.

PHIVOLCS reiterated that entry into the six-km radius Permanent Danger Zone (PDZ) should not be allowed.

Entry without vigilance into the Extended Danger Zone (EDZ) should likewise be prohibited, PHIVOLCS said.

Flying aircraft close to Mayon Volcano should also be prohibited, it added. —KG, GMA Integrated News
