Mayon Volcano in the Philippines erupted in a massive ash cloud Monday afternoon local time, prompting the threat associated with the deadly volcano to be raised from Level 3 to Level 4 by the Philippine Institute of Volcanology and Seismology (PHIVLOCS).
Effectively, that extends the danger zone to a minimum radius of 8 kilometers around the volcano, and it also means a hazardous eruption is possible within the next few days.
The ash column over the volcano was almost 10 kilometers high, and was accompanied by some pyroclastic flow, which contain hot gas and tephra, or fragmented volcanic material.
Classes in all levels across Albay are suspended, and residents are advised to wear face masks and stay indoors
