The Philippines raised the alert level at its Mayon volcano on Monday after a loud explosion in the wake of increased activity made a hazardous eruption likelier, prompting authorities to close all schools and urge residents to stay indoors.

A level 5 alert signifies a hazardous eruption is underway.

Mayon, the country’s most active volcano, has been spewing ash, lava, and pyroclastic material since January 13, displacing close to 40,000 residents in the central province of Albay.

The Philippine Institute of Volcanology and Seismology (Phivolcs) raised its alert on Mayon to level 4, signifying a hazardous eruption is imminent, from level 3, which warns that such an eruption could be “weeks or even days” away.

“We strongly advise all people, both residents and tourists, to avoid the danger zone, and airlines to avoid flying near the volcano summit,” agency chief Renato Solidum told a news conference.

The danger zone around the 2,462-metre volcano has been expanded to a radius of 8 km, he added.

Solidum said the agency had recorded increased seismic activity and “lava fountaining and a summit explosion” from Sunday night, indicating more explosions ahead, including a hazardous eruption.

Albay province has run out of emergency funds and more people would be evacuated once government financial help arrived, said provincial governor Al Francis Bichara.

He ordered schools to suspend classes, amid ash fall warnings following the explosion at the volcano.

“In some areas...it’s already zero visibility, especially along the foot of the volcano,” he told CNN Philippines, adding that strong winds could carry ash to distant towns.  “(People) have to stay home and if they intend to get out of their houses, they have to wear masks,” Bichara said.

The Philippines' chief volcanologist warned on Monday of a possible hazardous eruption at Mount Mayon "within weeks or even within days", as magma continued to pile up at the summit of the Southeast Asian country's most active volcano.
