Mayon volcano keeps pushing glowing rockfalls and lava down its slopes as 287,000 Filipinos remain locked out of the danger zone

As of late May 2026, Mayon Volcano is still forcing the largest displacement in Albay province in years. Incandescent rockfalls continue to tumble down the volcano’s upper slopes at night, lighting up the cone in orange streaks visible from towns kilometers away. Slow-moving lava feeds a growing dome near the summit, and superheated avalanches of gas and rock have swept into gullies on the southeastern flanks. Roughly 287,000 residents remain barred from the permanent danger zone, according to Albay Provincial Disaster Risk Reduction and Management Office advisories, unable to return to farms, homes, and livelihoods that sit inside the exclusion perimeter the Philippine Institute of Volcanology and Seismology (PHIVOLCS) established when it raised the alert to level 3 on January 6, 2026.

That alert level, the midpoint on the agency’s five-tier scale, has now held for nearly five months. It has not been downgraded, and PHIVOLCS has given no public indication that a reduction is imminent. No deaths or injuries directly caused by the current eruptive phase have been confirmed in available reporting, but the prolonged displacement is taking a mounting economic and social toll on affected communities.

Dome collapses, not explosions, are driving the danger

The hazard Mayon poses right now is not the towering eruption column most people picture. Instead, lava that accumulates near the summit periodically gives way under its own weight, sending pyroclastic density currents — superheated mixtures of gas and rock fragments — racing downhill at high speed. PHIVOLCS Director Teresito Bacolcol described the mechanism in a briefing carried by the Associated Press in early January 2026, telling reporters that “there was no explosive eruption but a pyroclastic flow from cascading deposits,” a distinction that matters because it points to ongoing dome instability rather than a single violent blast. As long as fresh magma keeps arriving at the surface faster than gravity can clear it away, the cycle of buildup and collapse is likely to repeat.

AP reporting from that period confirmed that pyroclastic density currents were generated by collapsing lava on the upper slopes, and that nearly 200,000 people were counted in ash-affected areas by disaster officials. More than 5,400 residents evacuated as ashfall blanketed surrounding towns, on top of about 3,000 who had already left during an earlier escalation when PHIVOLCS first detected increased rockfall and dome growth. Those figures were relayed through wire aggregation of Philippine government data; specific National Disaster Risk Reduction and Management Council (NDRRMC) situation report numbers have not been independently confirmed in the sources reviewed here.

Satellite data shows the magma supply has not stalled

Instruments in orbit have backed up what observers on the ground are seeing. Thermal sensors have tracked a bright, persistent hotspot at Mayon’s summit consistent with an active lava dome and short flows on the upper flanks. Ultraviolet sensors have also detected elevated sulfur-dioxide (SO2) emissions, a key indicator volcanologists use to estimate how much fresh molten rock is reaching shallow depths. SO2 exsolves from magma as it rises and depressurizes; when the gas flux stays high between visible surface events, it typically means the underground supply line is still open.

That combination of a hot dome, continuing rockfalls, and elevated gas output paints a picture of a volcano whose plumbing system remains pressurized, even though the surface activity has stayed below the threshold for a full explosive eruption.

Big gaps remain in the public data

Despite the clear signs of unrest, several important questions do not yet have public answers. PHIVOLCS has not released daily rockfall counts, lava effusion rates, or real-time SO2 flux values in its publicly available bulletins, making it difficult for outside analysts to judge whether the magma supply rate is accelerating, holding steady, or winding down. Seismic data that would reveal how shallow the intrusion has become are summarized in broad terms but not broken down into detailed event catalogs.

Displacement figures also carry gaps. The 287,000 number for residents locked out of the danger zone has appeared in provincial disaster office advisories, but the reporting reviewed here does not include a granular census breakdown by municipality or barangay. It remains unclear how many of those affected are rice and coconut farmers, small-business owners in towns such as Camalig, Daraga, or Guinobatan, or informal workers whose income depends entirely on access to land within the exclusion belt. No detailed primary statement from local government units on school closures, crop losses, or livelihood disruptions inside the extended danger zone has surfaced in the current source set. Likewise, no specific accounting of government aid — such as cash transfers, food packs distributed, or temporary employment programs — has been confirmed in the sources available for this report.

Mayon has done this before, with different outcomes

The archived eruption record maintained by the Smithsonian’s Global Volcanism Program shows that Mayon has cycled through similar rockfall-and-flow sequences many times. In some past episodes, alert levels stayed elevated for weeks or months as lava slowly advanced and collapsed, only to subside when the magma supply decreased. In others, a stretch of dome growth and collapses was followed by discrete explosive bursts that sent ash higher into the atmosphere and forced wider evacuations. That historical variability is precisely why PHIVOLCS has not predicted what comes next, and why the agency has kept the exclusion zone in place rather than gambling on an early all-clear.

What displaced families are facing after nearly five months

For the roughly 287,000 people on the wrong side of the exclusion perimeter — displaced since early January 2026, now approaching five months away from home — the situation is straightforward but grinding. Entry into the danger zone is prohibited except for authorized personnel. Farmers who depend on plots inside the restricted area face an indefinite wait and mounting risk of debt or lost harvests. Families sheltering in evacuation centers or with relatives must manage crowded conditions, limited privacy, and the challenge of keeping children in school and adults earning income far from home.

The clearest signal to watch is the next PHIVOLCS bulletin. A drop to alert level 2 would shrink the exclusion zone and allow some returns, typically with continued restrictions near gullies and drainage channels that could funnel lahars or future flows. A rise to level 4 would signal that a hazardous eruption is imminent, potentially triggering wider evacuations, road closures, and disruptions to regional air traffic if ash clouds climb high enough. Until that update comes, the safest course for displaced families is to stay registered at official evacuation sites or with local authorities, where they remain eligible for government relief supplies and any additional assistance that provincial and national agencies may announce as the crisis stretches on.
