This map shows how far smoke spread in the aftermath of theNavotas landfill fire, which broke out at approximately 8PM on April 10, 2026. The time-lapse mapshows hourly snapshots from 7:45AM (featured) to 3:45PM on the following day, April 11.
Darkercolors indicate higher levels of nitrogen dioxide, a proxy for smoke extent, which can be measuredduring daytime using satellite data.
On the morning of 11 April 2026, high nitrogen dioxide was observed over Navotas City, withelevated levels extending as far as Bataan due to predominantly westward wind from Navotas.By the afternoon of 11 April, NO₂ concentrations had decreased but remained relatively highacross Metro Manila.Observations are consistent with reports and measurements on the ground that the air qualityimpacts of the landfill fire extended beyond the immediate vicinity.
This demonstrates how satellitedata allows us to monitor air quality, as well as other impacts on the Philippine environment
