Philippine authorities raise alert as Mayon volcano erupts
The Philippines’ most active volcano has exploded sending a huge column of ash into the sky and prompting authorities to raise the alert level - meaning a hazardous eruption may be imminent.
The footage, captured on January 21, shows a massive plume of ash and steam rising up in the air.
Thousands of residents have been evacuated since Mayon started acting up more than a week ago.
Mount Mayon has erupted about 50 times in the last 500 years, reports say.
