Manila (dpa) – An active volcano in the eastern Philippines emitted steam plumes Monday as scientists warned that pressure was building up inside the crater.
Mayon Volcano in Albay province, 330 kilometres south-east of Manila, quieted down on the weekend with fewer volcanic earthquakes and rock falls, according to the Philippine Institute of Volcanology and Seismology.
But it said the steaming has been monitored since Sunday, and could indicate that pressure was building up inside the country’s most active volcano as magma moves up.
More than 50,000 people have been evacuated from an expanded eight-kilometre danger zone around Mayon since last week, after warnings that the volcano could erupt soon.
Albay Governor Joey Salceda said authorities were also moving nearly 20,000 farm animals to ensure that residents do not have to return to their homes.
“We cannot take chances that might compromise the safety of our residents,” he said.
The 2,472-metre volcano is famous for its nearly symmetrical cone, which attracts thousands of foreign and local tourists every year.
