Authorities reported that a lava collapse was observed at around 4:30 p.m., prompting renewed calls for vigilance.
“Manatili pong naka-alerto, laging mag-ingat, at sumunod sa paalala at babala ng mga awtoridad,” the OCD reminded in its advisory.
Volcanic activity remains ongoing, with lava effusion and flow previously recorded along key gullies. Lava was seen descending through the Basud (3.8 km), Bonga (3.2 km), and Mi-isi (1.3 km) channels on Friday.
