Satellite imagery has confirmed the extensive spread of smoke from the Navotas landfill fire, showing that air pollution from the incident reached as far as Bataan.
The fire, which broke out at around 8:00 p.m. on April 10, 2026 in Navotas City, left a significant environmental footprint that extended well beyond its immediate surroundings. A time-lapse map tracking the incident captured hourly snapshots from 7:45 a.m. to 3:45 p.m. on April 11, offering a clear picture of how the smoke dispersed throughout the day.
Using satellite-based measurements of nitrogen dioxide (NO₂)—a key indicator used to estimate smoke concentration—data showed intense pollution levels over Navotas City by the morning of April 11. Driven by prevailing westward winds, the smoke plume traveled across Manila Bay, reaching parts of Bataan and affecting a broader swath of Luzon.
By the afternoon, NO₂ levels began to decline, but concentrations across Metro Manila remained elevated, signaling lingering air quality concerns even after the initial spread had subsided.
These satellite observations align with ground reports and air quality measurements, confirming that the impact of the landfill fire was not confined to Navotas alone. Instead, it underscores how environmental incidents in urban centers can rapidly affect neighboring regions.
The findings also highlight the growing importance of satellite monitoring in assessing air quality and environmental risks in the Philippines, providing authorities and the public with timely, science-based insights during critical events.
