Mt. Mayon in Albay showed signs of activity for the second straight day on Saturday as government volcanologists continued to keep the volcano under close watch.
The Philippine Institute of Volcanology and Seismology (Phivolcs) reported on Sunday there was at least one rockfall and a moderate emission of white steam plumes from the crater.
Phivolcs also observed a “faint” crater glow on Saturday night and emission of sulfur dioxide emission.
There was also a slight ground deformation, Phivolcs said.
Mayon remained at Alert Level 1, which means abnormal activity in the volcano.
“Although this means that presently no magmatic eruption is imminent, it is strongly advised that the public refrain from entering the 6-km radius Permanent Danger Zone (PDZ) due to the perennial life-threatening dangers of rockfalls, landslides/avalanches at the middle to upper slope, sudden ash puffs and steam-driven or phreatic eruptions from the summit,” Phivolcs said.
It also warned the public to avoid active stream or river channels and areas identified as lahar-prone.
