The Philippine Institute of Volcanology and Seismology (PHIVOLCS) has observed a weak lava effusion from the summit of Mayon volcano early Saturday morning.

According to the state seismologist, the weak lava effusion from Mayon's summit crater marks its fifth month.

Mayon has seen "persistent slow-moving lava flow and rockfall on the Miisi and Bonga Gully."

At 6:36 p.m., a short-lived burst at the summit had been detected, PHILVOCS said.

The footage was taken by the Mayon Volcano Observatory cameras at Ligñon Hill and Mayon Resthouse.

Meanwhile, Alert Level 3 is still maintained over Mayon.

Alert level 3 means relatively high and increasing unrest, including numerous b-type earthquakes, accelerating ground deformation and rockfalls, increased vigor of fumaroles, and gas emissions.
