LOOK: Mayon Volcano continues to shed 'uson,' lava flows, rockfalls on Tuesday night

Mayon Volcano on Tuesday night continued to shed incandescent pyroclastic density currents (PDCs) and rockfalls amid the 28th consecutive day of its effusive eruption, state volcanologists said.

In social media posts, the Philippine Institute of Volcanology and Seismology (PHIVOLCS) said incandescent PDCs or “uson” and rockfalls “continue to be shed within two kilometers of the summit crater onto the Miisi (south), Bonga (southeast) and Basud (east) Gullies, which are also being fed by slow-moving lava flows.”

“Alert Level 3 prevails over Mayon and entry into the 6-km Permanent Danger Zone should be prohibited,” it stressed.

PHIVOLCS also shared a time-lapse video taken between 8 p.m. and 8:29 p.m. Tuesday which showed the glowing PDCs and slow-moving lava flows descending the volcano’s slopes.

Earlier, state volcanologists also uploaded a time-lapse video of the incandescent lava flows, PDCs, and rockfalls being shed by Mayon Volcano at past midnight Tuesday.

They added that as of Tuesday, they observed a crater glow, lava flow, plumes, and ground deformation at Mayon Volcano.

As of Tuesday morning, PHIVOLCS logged nine volcanic earthquakes, 304 rockfall events, and 68 PDCs from the volcano. — JMA, GMA Integrated News
