Philippine Institute of Volcanology and Seismology (PHIVOLCS) shared the video of the eruption which shows lava begin to pour down the slope before a ash cloud was released.
The video was filmed at 6.11am local time yesterday from a volcano observatory in Legazpi City, Albay, in the eastern Philippines.
Hot red lava spewed out of the crater six times between 6.02am local time on Wednesday and 3am local time on today, according to PHIVOLCS.
The lava fountains reached 400m to 500m high, ash plumes soared up to 5km above the crater, 13 tremors were recorded and there were “numerous rockfall events”.
A huge plume of ash billowed from the glowing peak of the Philippines’ most active volcano again and magma continued to move below the ground today.
But nevertheless there were serene scenes today in Legazpi City were families were seen gathered today while looking out towards the erupting volcano.
A young child was pictured looking worried as the woman holding him watched the volcano, while another villager leaned out of a tuk tuk to get a better view.
Mayon’s unrest has displaced about 75,500 people, the majority of whom are in evacuation centres, where children lined up for meals and parents braced for the possibility of a long stay away from home.
“We are worried. We got used to the volcano, but we are still afraid,” said one evacuee, Irene Agao.
“If only we could, we would go home right now, away from this evacuation centre, but we need to stay. Because we never know what else the beautiful Mayon volcano will do.”
Government offices and schools have been closed in 17 towns and municipalities and 66 flights have been cancelled in recent days.
The provincial government has expanded the danger zone around the 2,462m (8,077ft) volcano to a radius of 9km, up from the Phivolcs-recommended 8km no-go zone.
The alert remains at level 4, just one notch below the highest level of 5.
PHIVOLCS said: “The public is strongly advised to be vigilant and desist from entering the eight (8) kilometer-radius danger zone, and to be additionally vigilant against pyroclastic density currents, lahars and sediment-laden streamflows along channels draining the edifice.
“Civil aviation authorities must also advise pilots to avoid flying close to the volcano’s summit as ash from any sudden eruption can be hazardous to aircraft.”
