On March 15, 2026, the Philippine Institute of Volcanology and Seismology (PHIVOLCS) raised the alert level for Mayon Volcano in Albay to Level 3, indicating intensified unrest and possible eruptions. This decision comes on the back of an alarming spike in volcanic activities, including a reported 279 volcanic earthquakes within a 24-hour observation period.
Current Volcanic Activity
According to PHIVOLCS, the monitoring data from the past 24 hours, spanning from midnight of March 14 to midnight of March 15, revealed significant volcanic unrest. Among the key indicators were:
- Seismic Activity: A total of 279 volcanic earthquakes were recorded, pointing towards increased magmatic movement beneath the volcano.
- Lava Effusion: There are ongoing lava flows observed in several gullies, specifically Basud (3.8 km), Bonga (3.2 km), and Mi-isi (1.3 km). This has been accompanied by sporadic minor strombolian activity, indicative of explosive eruptions.
- Sulfur Dioxide Emission: The sulfur dioxide (SO2) emissions peaked at 2430 tonnes per day on March 14, 2026, an alarming figure that suggests significant volcanic gas release.
- Crater Glow: The volcano exhibited visible crater glow, suggesting ongoing magma movement.
Implications of Alert Level 3
Raising the alert to Level 3 means that the general public, especially residents living within a six-kilometer radius of the volcano, are advised to evacuate and refrain from entering the area. The Permanent Danger Zone (PDZ) outlines areas that pose significant hazards such as:
- Lava flows and fountaining
- Rockfalls and landslides
- Pyroclastic density currents, which can occur during moderate-sized explosions
- Lahars, especially during prolonged rainfall, which could trigger mudflows.
Witnesses and Local Reactions
Historical Context of Mayon Volcano
Mayon Volcano is the Philippines' most active volcano, known for its nearly perfect cone shape. Its history of eruptions dates back to the 16th century, with the most powerful recorded eruption occurring in 1814, which destroyed the town of Cagsawa and resulted in numerous casualties. The volcano is currently regarded as a major tourist attraction in the region, drawing thousands of visitors annually; however, its activity poses significant risks to nearby communities.
Safety Recommendations and Preparedness
PHIVOLCS recommends that residents maintain situational awareness, particularly those located near the PDZ. In the event of an evacuation order, individuals should have emergency bags ready, including essentials such as food, water, medications, important documents, and a flashlight. The public is urged to stay updated through official channels and heed the advice from local authorities.
A timetable for the resurgence of volcanic activity can only be speculated. The geological framework of such activity is complex and unpredictable. Continuous monitoring by PHIVOLCS will play a crucial role in providing timely updates and warnings to mitigate risks associated with volcanic disturbances.
Looking Ahead
Moving forward, the situation will depend on the geological behavior of Mayon Volcano. PHIVOLCS will continue to monitor the volcanic activity closely and provide regular briefings. The public is encouraged to take all alerts seriously and act quickly in response to potential evacuation orders. The next scheduled briefing by the agency will take place on March 16, 2026, where officials will reassess the volcanic activity and update the public accordingly.
Officials stress the importance of adhering to evacuation protocols. Community preparedness is vital in safeguarding lives, particularly in a region that has historically faced the brunt of volcanic eruptions. Residents are advised to remain vigilant and prepared for unforeseen developments as Mayon continues to show signs of increased unrest.
PHIVOLCS has urged everyone to avoid any flying activities near the volcano as well, reiterating that such operations could pose serious risks not only to the aircraft but also to people on the ground.
