- Seismology agency: Mount Mayon has shown "a noticeable escalation of unrest"
- It raises the alert level to "critical," saying an eruption could happen within weeks
- Authorities in the region begin evacuating more than 10,000 people from the area
Thousands of people are being evacuated from the area around an active volcano in the Philippines after the country's seismology agency issued an alert saying a hazardous eruption could happen "within weeks."
Mount Mayon, which towers over the city of Legazpi in the central Philippines, has shown "a noticeable escalation of unrest," the Philippine Institute of Volcanology and Seismology said in a bulletin late Monday.
Molten lava and volcanic gas are making the mountain's crater glow red, it said.
The agency raised the alert level to "critical" for Mayon, which is famed for its near-perfect conical shape. Critical is the agency's third highest alert level after eruption and imminent eruption.
Authorities in the region of Albay responded Tuesday by launching efforts to relocate more than 10,000 people from a 6-kilometer radius around the volcano, the official Philippines News Agency reported.
