MANILA - A thick cloud of gray and white smoke filled the skies near Mount Mayon, the country's most active volcano, following a lava collapse Monday morning. 

The Philippine Institute of Volcanology and Seismology (Phivolcs) said it monitored an ash column coming from the volcano due to lava collapse.

Residents in the 7-kilometer extended danger zone near the volcano have been evacuated as Alert Level 3 has been raised by authorities on Sunday. 

Authorities advised people to cover their noses and mouths with a damp, clean cloth or dust mask if they were exposed to ash from the eruptions. Aircraft are also told to avoid flying close to the volcano.

Mayon's most destructive eruption was in February 1841, when lava buried a town and killed 1,200 people. It last erupted in 2014, spewing lava and forcing thousands of people to evacuate.
