Its crater glow is still obscured as a flux of sulfur dioxide totaling 702 tons per day escapes the volcano.
Phivolcs further said that Mayon’s plume, or the mixture of gases and particles that escape its crater, is at a “moderate emission” and is drifting west-southwest.
Entering the volcano’s six-kilometer Permanent Danger Zone and flying aircraft close to Mayon are prohibited.
Mayon is still under Alert Level 2, according to Phivolcs’ latest observation summary.
Previously, state seismologists warned that phreatic, or steam-driven, eruptions happen suddenly or without any precursors and are always possible from Mayon Volcano, even at Alert Level 0.
