Lava is still pouring down three sides of Mayon volcano in the Philippines, and more than 287,000 people who fled their homes since the eruption began in early 2026 have yet to return. The molten rock has traveled nearly four kilometers down one drainage channel alone, pyroclastic flows have blanketed nearby towns in ash, and evacuation shelters are buckling under extreme heat. With the wet season closing in, the crisis in the Bicol region shows no sign of easing.
The eruption right now
Mayon, one of the most active volcanoes in the Philippines, began its current eruption in early 2026 when lava started flowing from the summit crater. The Philippine Institute of Volcanology and Seismology (PHIVOLCS) raised the alert level, and the volcano has remained in a state of heightened unrest ever since.
A volcanic activity report published May 8, 2026, by the Smithsonian Institution’s Global Volcanism Program, which aggregates PHIVOLCS monitoring bulletins, offers the most detailed public snapshot of conditions. Lava flows have reached 3.8 kilometers down the Basud gully on Mayon’s northeastern flank, 3.2 kilometers in the Bonga drainage, and 1.6 kilometers in the Mi-isi channel. Seismicity remains elevated, and sustained crater glow at night indicates that fresh magma is still reaching the surface.
Satellite imagery from NASA’s Earth Observatory has tracked the progression of lava, sulfur dioxide plumes, and the scars left by pyroclastic density currents (PDCs) over the past several months. On May 2, according to The Associated Press, a collapse of accumulated lava deposits triggered a pyroclastic flow and heavy ashfall that forced more than 5,400 additional people to evacuate.
The scale of displacement
The Department of Social Welfare and Development (DSWD) has reported that more than 70,000 families in Region V, equivalent to over 286,000 individuals, are displaced. The agency released those figures through its Disaster Response Operations Monitoring and Information Center (DROMIC) and repeated them during a media forum in May 2026 where officials also announced plans to retrofit evacuation centers with better ventilation. The exact date of the forum has not been specified in the available DSWD materials.
That retrofit push reflects a compounding problem: the Philippines has been experiencing extreme heat, and crowded shelters built for short-term use are becoming dangerously hot after months of continuous occupation. DSWD has not published detailed health data from the centers, but the agency’s own language about the urgency of ventilation upgrades signals that conditions inside are deteriorating.
The AP’s reporting, filed around early May, placed the broader affected population at nearly 200,000, lower than DSWD’s 286,000 count. The gap likely reflects different reporting dates and methodologies. DSWD’s figure appears to be cumulative across multiple evacuation waves since the eruption began, while the AP snapshot captured conditions at a single point. Both numbers are credible within their own framing, but the DSWD total, drawn from the agency’s ongoing tracking system, offers the more comprehensive picture of the crisis to date.
Following the early-May pyroclastic flow events, the DSWD’s Response Cluster convened an emergency meeting to coordinate relief across agencies. The session focused on tracking internally displaced populations, managing shelter logistics, and aligning supply distribution as the eruption continued.
What remains unclear
Several important questions do not yet have public answers. PHIVOLCS has been monitoring sulfur dioxide output, a key indicator of whether magma is still rising, but real-time SO2 flux data after May 8 has not appeared in the international reporting channels reviewed for this article. Whether emissions are climbing, holding steady, or declining will shape forecasts about how long the eruption continues.
The current PHIVOLCS alert level for Mayon has not been specified in the most recent Smithsonian or DSWD reports available. Alert levels in the Philippine system range from 0 (no alert) to 5 (hazardous eruption in progress), and the distinction matters because it determines the size of the mandatory evacuation zone and the restrictions on farming and travel near the volcano.
Ground-level conditions are also poorly documented. No direct statements from local officials in Albay province or from displaced families have surfaced in the primary institutional sources. That means basic questions, such as how many people have lost crops or livestock, whether children in shelters are still attending school, and how families are managing livelihoods months into displacement, remain unanswered in the public record. No verified data on agricultural or economic losses has been published by the agencies tracked here, leaving the material toll of the eruption beyond displacement figures effectively unmeasured in available sources. International news coverage has provided some broader context, but the institutional reporting is largely silent on the human toll beyond headcounts.
What the wet season could change
The approaching rainy season, which typically begins in June across the Bicol region, adds a layer of risk that volcanologists and disaster managers have been warning about for months. When heavy rain falls on loose volcanic deposits, it can trigger lahars, which are fast-moving flows of water, mud, and debris that follow river channels and can bury communities far from the volcano itself. Mayon’s steep, symmetrical cone and well-defined drainage gullies make it especially prone to lahars once the rains arrive.
For the 287,000 people still in shelters, the wet season also threatens to worsen living conditions. Evacuation centers that are already struggling with heat could face flooding, leaks, and waterborne disease outbreaks. DSWD’s retrofit plans will need to account for rain as well as heat, a dual challenge the agency has acknowledged but not yet detailed publicly.
Why the eruption is not over and what the instruments show
The eruption at Mayon is not a single event but an ongoing process that has been reshaping the landscape and the lives of hundreds of thousands of Filipinos since the start of 2026. The strongest evidence, from PHIVOLCS instruments relayed through the Smithsonian’s Global Volcanism Program, NASA satellites, and DSWD tracking systems, all points in the same direction: the volcano is not done, and neither is the displacement crisis it has created.
