The Philippines' Mayon Volcano crater glowed bright orange as it spewed lava down its slopes on Monday night.

Footage shows the summit of the 'perfect cone' volcano illuminated by the streams of at around midnight on June 12.

Locals and tourists walking along Legazpi Boulevard in Albay province marvelled at the spectacular sight despite the danger it posed.

Onlooker Jonas Sergio said: 'The eruption was scary, but it was so beautiful at the same time. I hope no violent explosion occurs.'

State volcanologists have hoisted Alert Level 3 indicating a 'high level of unrest' over Mayon Volcano last Thursday. They said the unrest could last for months, and the high-risk zone may be expanded should the eruption intensify.

Speaking to local reporters, Teresito Bacolcol, director of the Philippine Institute of Volcanology and Seismology (PHIVOLCS), said: 'Based on our experience, this activity may persist for a few months. If the erutpion were violent, this would probably take a few days to weeks, but when it is slow like this, it would probably take several months.'

The Albay Public Safety and Emergency Management Office said around 15,241 people were staying in evacuation centres as of June 14.

The Albay local government has declared a state of calamity in the province last Friday, allowing authorities to tap emergency funds to support affected residents.

Mayon Volcano - a popular tourist attraction renowned for its 'perfect' conical shape - is the most active volcano in the Philippines. It last erupted in 2018, displacing around 40,000 residents.
