The Philippines' most active volcano has exploded for the second time today, spewing more molten lava and steam into the air and forcing more than 56,000 residents to flee.

The footage, captured from a village nearby, shows a huge ash plume shooting up to the sky moments after the explosion.

Authorities on Monday raised the alert level to four on a scale of five- meaning a hazardous eruption is possible within hours or days.

Mount Mayon has erupted about 50 times in the last 500 years, reports say.

After yesterday's large ash explosion prompting authorities to raise the alert level - meaning a hazardous eruption may be imminent, Mayon volcano has erupted several times Tuesday, shooting up another column of ash in Albay province in the Philippines.

The footage, captured on January 23, shows another massive plume of ash and steam rising up in the air for the second time and a close-up of the resulting pyroclastic flow. A news report from a local radio station, DWBS-AM, can also be heard in the video

At least 30,000 residents have been evacuated since Mayon displayed increased abnormal volcanic activity more than a week ago.
