PHIVOLCS: Renewed slow effusion of lava monitored in Mayon

(Eagle News)–A renewed slow effusion of lava was monitored in Mayon on Wednesday night, the Philippine Institute of Volcanology and Seismology said. According to PHIVOLCS, the slow effusion was seen beginning 8:49 p.m. With the effusion, PHIVOLCS said  advanced lava flow was detected in the Bonga, Mi-isi and Bangud gullies and generated incandescent rockfall within two kilometers from the summit crater. In its update on Thursday, PHIVOLCS said a slow lava flow of 3.4 kilometers […]

No volcanic quakes monitored in Mayon in last 24 hours but Alert Level 2 still in place: PHIVOLCS

(Eagle News)–No volcanic earthquakes were monitored in Mayon in the last 24 hours, the Philippine Institute of Volcanology and Seismology said. However, an alert level 2 remains in place over the volcano. PHIVOLCS said the raising of the alert level from 1 was after daily visual and camera monitoring of the summit crater revealed a “continued aseismic growth” of its lava dome. According to PHIVOLCS, as of October 4, the lava dome has increased in […]
