Lava continued to spill from Mayon Volcano in Albay for the 187th consecutive day on Saturday, according to the Philippine Institute of Volcanology and Seismology (Phivolcs).
In an advisory, Phivolcs shared camera footage showing the volcano's lava effusion and lava flow, recorded from 4:11 a.m. to 4:40 a.m. on July 11, 2026.
“Effusive eruption of Mayon Volcano continues for its 170th consecutive day, generating incandescent lava flows, pyroclastic density currents (PDCs), locally known as “uson,” and rockfalls,” Phivolcs said.
Monitoring conducted from 12:00 a.m. on July 10 to 12:00 a.m. on July 11 showed that lava had advanced up to 3.8 kilometers along the Basud Gully, 3.2 kilometers along the Bonga Gully, and 1.2 kilometers down the Mi-isi Gully.
Phivolcs also recorded 10 volcanic earthquakes, 241 rockfall events, and six pyroclastic density current signals.
Phivolcs said, “Alert Level 3 remains in effect over Mayon Volcano.”
The agency reiterated that entry into the six-kilometer Permanent Danger Zone (PDZ) remains strictly prohibited due to the continued threat of lava flows, pyroclastic density currents, rockfalls, and other volcanic hazards.
