What the satellites saw
Every pixel VIIRS returned inside 10 km of this fire: 225 in daylight, 0 on the night pass. A pixel is 375 m, so the squares are drawn at the size the measurement has.
Where
Coastline and borders from Natural Earth at 110 m — regional context, not a survey. Each layer above is its own address, so a view can be shared.
A fire was first detected here at 16:45 UTC on 10 October 2026, 49 km NE of Alenquer in Pará, Brazil. At its most recent pass it was putting out 5,829 megawatts of radiative power across 225 separate satellite detections.
The detections span about 6.1 km of ground.
No settlement in our index has population recorded within 25 km.
When the satellite first saw it
In local solar time the first detection falls at 13:07, which is the early afternoon. VIIRS passes about 01:30 and 13:30 local solar, so this is when the satellite looked: the fire began somewhere in the twelve hours before.
The fire was caught on a single satellite pass, so we can say when it was first seen but not how long it burned.
What this ground has done before
This ground has burned before. Our archive records fire here in 2012, 2013, 2014, 2015, 2016, 2017, 2018, 2019, 2021, 2023, 2024, 2025, 2026, across 48 days, most recently on 2026-10-09.
Wind and weather
At the fire, wind was 14 km/h from the E, carrying smoke and embers towards the W. Temperature 36°C, relative humidity 36%.
Twelve hours on, the forecast has wind at 12 km/h from the E. These are model figures at roughly 10 km resolution, not a reading taken at the fire.
How it compares
By radiative power this is the 10th largest fire burning anywhere on Earth in the current window.
Where analysis would go
This fire is below the threshold at which the screening pass records a score.
Read from satellite detections and weather. No roads, no land cover, no ground visit.
What else this page knows
Each of these is attached to every fire, including this one.
A detection is a heat signature at 375 m, about three hours behind the satellite. Cloud, smoke and canopy hide fires; each satellite passes twice a day. Not for evacuation or life-safety decisions — follow your local fire service.
