Five months after Mayon Volcano began erupting on January 6, 2026, nearly 290,000 people across the Bicol region of the Philippines remain displaced, and lava flows have stretched 3.8 kilometers down the Basud channel on the volcano’s southeastern flank. The eruption has produced daily rockfalls, pyroclastic density currents, and sudden secondary explosions, all while holding at Alert Level 3 on the Philippine Institute of Volcanology and Seismology’s five-level scale. By duration alone, the event already ranks among the longest effusive episodes in Mayon’s recorded history, surpassing the roughly two-month eruption that forced mass evacuations in mid-2023.
For the tens of thousands of families packed into evacuation centers across Albay, Camarines Sur, and Sorsogon provinces, the crisis has become a grinding test of endurance, compounded by extreme heat that is straining shelters and stretching government resources thin.
A lava flow that keeps advancing
PHIVOLCS confirmed the eruption’s start on January 6 and has issued daily bulletins tracking lava movement, rockfall counts, and gas emissions ever since. The Smithsonian Institution’s Global Volcanism Program, which compiles and cross-references those bulletins, logged the same start date in its weekly activity reports. By February 8, the most recent measurement available in publicly accessible PHIVOLCS bulletins, lava had traveled 3.8 kilometers down the Basud gully, the longest single flow recorded during this episode.
To put that distance in perspective, the Basud channel runs toward communities on Mayon’s southeastern side. The permanent danger zone extends six kilometers from the summit crater, meaning the flow front in early February was still within that exclusion area. But effusion rates can shift quickly. A longer flow, or a new lobe breaking toward a different channel, could bring molten rock closer to barangays that sit just outside the restricted perimeter.
Alert Level 3 means a hazardous eruption remains possible. On PHIVOLCS’ scale, Level 4 signals that such an eruption is imminent, and Level 5 means one is underway. The fact that Mayon has held at Level 3 for months without either escalating or subsiding reflects the volcano’s stubborn, slow-burning character during this episode.
The scale of displacement
The Department of Social Welfare and Development reported, in a release dated February 2026, that more than 70,000 families, totaling over 286,000 individuals, have been affected across Region V. “We continue to provide round-the-clock assistance to displaced families in evacuation centers,” a DSWD Region V spokesperson said in that release, adding that the agency has sustained relief operations for displaced Bicolanos while simultaneously retrofitting evacuation centers to cope with dangerously high temperatures. The agency’s outputs have included family food packs, ready-to-eat meal boxes, non-food items such as sleeping mats and hygiene kits, and mobile kitchens deployed directly to shelters.
Those aggregate numbers, however, come from a single DSWD release covering the entire region. No publicly available breakdown separates families still living in evacuation centers from those who have found temporary housing with relatives or in private arrangements. Without that granularity, it is difficult to pinpoint which municipalities face the greatest shelter burden or where heat-related health risks are most concentrated. What is clear is that the displacement dwarfs the 2023 eruption, when roughly 13,000 families were evacuated at the peak of activity.
Secondary explosions and layered hazards
Beyond the main lava effusion, secondary explosions have added an unpredictable layer of danger on Mayon’s slopes. These blasts occur when hot volcanic material comes into contact with water or loose, unstable debris, triggering sudden outbursts that can hurl rocks and ash without warning. The Philippine Information Agency published a detailed explainer on secondary explosions at Mayon, emphasizing that these events are distinct from the primary eruption but can be just as lethal for anyone inside the danger zone. PHIVOLCS measurements cited in that reporting confirm the same 3.8-kilometer flow distance, corroborating the figure across multiple government channels.
Satellite imagery has provided an independent line of confirmation. A feature from NASA’s Earth Observatory shows thermal signatures of active lava and ash plumes, placing the 2026 activity in a broader volcanological context. Thermal data from orbit does not replace ground-level measurements, but it validates that lava is moving along specific channels and that volcanic gases are reaching certain altitudes, reinforcing the picture assembled by PHIVOLCS field teams.
Where this eruption fits in Mayon’s history
Mayon is one of the most active volcanoes in the Philippines, with dozens of recorded eruptions since the 1600s cataloged by the Smithsonian under volcano number 273030. Its deadliest event, in 1814, buried the town of Cagsawa and killed more than 1,200 people. Major eruptions in 1984, 1993, and 2018 each triggered large-scale evacuations, but most of those episodes lasted weeks, not months.
The 2023 eruption, which ran from roughly June through July of that year, produced lava flows reaching approximately three kilometers and prompted PHIVOLCS to raise the alert to Level 3 before activity tapered off. The 2026 episode has already exceeded that benchmark in both duration and flow length. Describing it as “among the longest” effusive eruptions in Mayon’s recorded history is defensible when limited to the modern instrumented era, which covers the past several decades of detailed monitoring. Extending that claim across four centuries of activity would overstate what the historical record can support, since accounts from the 18th and 19th centuries often describe “rivers of fire” or “months of activity” without precise measurements.
A full geophysical comparison between 2023 and 2026, including sulfur dioxide flux and seismic energy release, would require access to internal PHIVOLCS datasets that have not been made public. For now, the comparison rests on the two metrics that are available: how long the eruption has lasted and how far the lava has traveled.
What displaced families are still waiting for
The most immediate question for the nearly 290,000 affected Filipinos is when they can go home. The answer depends on variables that no one can fully predict: whether effusion rates hold steady, accelerate, or finally decline; whether PHIVOLCS raises or lowers the alert level; and whether the rainy season, which typically begins in June, triggers lahars that could reshape the hazard map entirely. Lahars, fast-moving flows of volcanic debris and water, have historically caused destruction well beyond Mayon’s lava-flow zones, and the thick deposits from months of eruption have loaded the slopes with fresh material.
DSWD’s evacuation-center retrofits remain a black box. The agency referenced the work in press materials, but no primary documents detailing costs, heat-mitigation standards, or completion timelines have appeared through Philippine government transparency channels. Families in shelters are enduring some of the hottest months of the year with limited information about when, or whether, conditions will meaningfully improve.
For residents and local officials, the practical takeaway from the available evidence is sobering. The confirmed lava-flow length and persistent Alert Level 3 status indicate that the permanent danger zone is likely to remain closed for an extended period. The scale of displacement means that any premature return to high-risk areas could put tens of thousands of people back in the path of rockfalls, pyroclastic currents, and secondary explosions. And the documented strain on evacuation infrastructure suggests that humanitarian needs will persist even if the eruption gradually wanes.
Why more transparent monitoring data would change the calculus for Bicol communities
More frequent public updates on lava-flow positions, detailed shelter-by-shelter statistics, and the eventual release of monitoring data would sharpen both scientific analysis and the day-to-day decisions that displaced families have to make. Until that transparency arrives, the picture of Mayon’s 2026 eruption remains a mix of solid measurements, carefully framed comparisons, and open questions that only time and continued observation will resolve.
