Why Has the Philippines Elevated Mayon Volcano Alert to Level 3?
Synopsis
Key Takeaways
- Alert Level 3 signifies a magmatic eruption and increased risks.
- Evacuations are advised within a six-kilometer radius.
- Residents must stay vigilant and follow local advisories.
- Significant rockfall and seismic activity have been recorded.
- Mayon Volcano is the most active volcano in the Philippines.
Manila, Jan 6 (NationPress) Philippine volcanologists have officially increased the alert level for Mayon Volcano, located in Albay province on Luzon island, to Alert Level 3. This decision stems from the identified "initiation of dome collapse pyroclastic density current,” as reported by the Philippine Institute of Volcanology and Seismology.
According to the institute, this elevation signifies that Mayon is undergoing a magmatic eruption of a summit lava dome. The situation presents heightened risks of lava flows and dangerous pyroclastic density currents (PDCs), which could impact the upper to middle slopes of the volcano and may lead to explosive activity in the near future.
The institute has observed multiple collapses of the unstable summit dome, which have resulted in a surge of rockfall incidents. Since January 1, 2026, there have been 346 rockfall events and four recorded volcanic earthquakes, in contrast to 599 rockfall events noted between November and December 2025, according to reports from Xinhua news agency.
In light of these developments, officials are recommending the evacuation of the six-kilometer radius permanent danger zone due to potential threats from PDCs, lava flows, rockfalls, and other volcanic hazards.
Authorities are advising residents in the vicinity to stay alert and adhere to instructions from local government bodies and disaster management officials, as the situation could change rapidly.
The institute emphasized the need for increased caution against PDCs, lahars, and sediment-laden stream flows in areas surrounding the volcano.
Earlier on January 1, PHIVOLCS raised the alert status from level 1 (low-level unrest) to level 2 (moderate level of unrest), indicating that magma is moving beneath the surface, which raises the chances of sudden explosive activity.
“This indicates current unrest caused by shallow magmatic processes that could lead to a hazardous magmatic eruption,” stated the institute in its advisory.
Furthermore, the public is strongly cautioned to remain vigilant and avoid entering the six-kilometer-radius Permanent Danger Zone, as this is critical in reducing risks associated with explosions and other related hazards.
Mayon is recognized as the most active volcano in the Philippines and possesses a long history of eruptions.
