Mount Mayon has spewed lava up to 600 metres (2,000 feet) high at times since Tuesday and its ash plumes stretched up to 5km above the crater.
The Australian government has pledged P31.6 million (Australian $775,000) worth of humanitarian support to individuals affected by the eruption of Mayon Volcano in Albay.
In its 8 a.m. bulletin on January 24, the Philippine Institute of Volcanology and Seismology (Phivolcs) said it had recorded five episodes of "intense but sporadic lava fountaining from the summit crater lasting seven minutes to one hour and twenty minutes" between 8:54 a.m., Tuesday and 3:57 a.m., Wednesday.
The institute said two "explosion-type earthquakes" had occurred, as well as 18 tremor events - some of which sent forth fountains of lava.
The authorities have ordered people to leave a danger zone stretching 8km from the volcano and yesterday shut down schools and businesses in Albay province.
A possible pyroclastic flow - characterized by a rapid movement of hot lava blocks, pumice, ash and gas along volcanic slopes - could reach up to 1.8 miles, Solidum said.
With Mayon under Alert Level 4, Albay officials said they expanded the permanent danger zone from six kilometres to eight kilometre, resulting anew in the voluntary evacuation of13,000 Legaspi City residents allowed to decamp on Sunday.
More than 56,000 people fled the surrounding areas and were taking shelter in evacuation camps, officials told the AP; the army and police were helping others move from their homes. "Let us not violate the natural law, avoid the prohibited zone, because if you violate, the punishment is the death penalty". Its most destructive eruption, in 1814, killed more than 1,200 people and buried the town of Cagsawa in volcanic mud. Some highways have also been closed, with ash showers making driving in some areas almost impossible, the provincial government said.
"It was like night time at noon, there was zero visibility in some areas because the ash fall was so thick", Nunez said.
Ash has started to cover Guinobatan, which lies 13 kilometers away from Mayon, said Mayor Ann Onjoco. "I tell my grandchildren to study hard so they can live elsewhere without a volcano to keep an eye on all your life".
