WATCH: Lava fountain seen at Mayon Volcano on its 79th day of effusive eruption

Mayon Volcano in Albay continued showing signs of unrest such as lava fountaining on Tuesday, the 79th consecutive day of its effusive eruption, the Philippine Institute of Volcanology and Seismology (PHIVOLCS) said.

PHIVOLCS shared time-lapse videos taken by the DOST-PHIVOLCS Quick Response Team from the Mayon Volcano Observatory which showed minor strombolian activity and short-lived lava fountaining.

The events occurred at 3:02 a.m. and 3:34 a.m.

"Effusive eruption at Mayon Volcano continues for the 79th consecutive day, generating incandescent lava flows, pyroclastic density currents (PDC) or 'uson', and rockfalls," PHIVOLCS said.

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

On Monday, lava effusion with lava flow also occurred at the volcano's Basud, Bonga, and Mi-isi gullies, together with minor strombolian activity and short-lived lava fountaining, PHIVOLCS said in its bulletin issued Tuesday morning.

A total of 180 volcanic earthquakes, 327 rockfalls and nine PDC signals were also logged on Monday, it added.

The volcano emitted 1,630 tonnes of sulfur dioxide on Monday as well.

Moderate plumes rising up to 500 meters tall were observed on Monday. These drifted in the west-southwest, west, and southwest directions.

PHIVOLCS reiterated that flying aircraft close to Mayon Volcano should not be allowed.

It added that the volcano poses hazards such as:

• rockfalls or landslides or avalanches
• ballistic fragments
• lava flows and lava fountaining
• PDCs
• moderate-sized explosions
• lahars during heavy and prolonged rainfall.
