(Eagle News)–Increased lava effusion was monitored in Mayon on Saturday evening, the Philippine Institute of Volcanology and Seismology said. PHIVOLCS said the effusion at the volcano, which remains under alert level 3, began at 10:10 p.m. It included an “abrupt intensification of incandescence” at the summit crater, and was followed by lava flow and rockfall at the Miisi and Bonga gullies. In its regular advisory, PHIVOLCS said 70 volcanic earthquakes including 65 volcanic tremors lasting […]
(Eagle News)–Mayon Volcano’s intensified activity continued on Sunday, Aug. 6, as a slow effusion of lava from the crater continued to feed the already-existing lava flows on the Bonga, Mi-isi, and Basud gullies. The Philippine Institute of Volcanology and Seismology said the lava flows “have maintained their respective advances to approximately 3.4 kilometers, 2.8 kilometers, and 600 meters from the crater.” PHIVOLCS said rockfall and pyroclastic density currents (PDCs) generated by collapses of the lava […]
(Eagle News)–Forty-five rockfall events were monitored in Mayon in the last 24 hours, the Philippine Institute of Volcanology and Seismology said. Apart from these, PHIVOLCS said monitored were 40 volcanic earthquakes. A slow effusion of lava flow spanning 2.8 and 3.1 kilometers along Mi-si and Bonga gullies was also monitored. Also detected were 600 meters of slow lava flow along the Basud Gully. PHIVOLCS said sulfur dioxide flux was pegged at 4113 tons per day. […]
