What the satellites saw
Every pixel VIIRS returned inside 10 km of this fire: 116 in daylight, 64 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 15:41 UTC on 11 October 2026, 8 km SSE of São José do Peixe in Piauí, Brazil. At its most recent pass it was putting out 2,448 megawatts of radiative power across 180 separate satellite detections.
The detections span about 6.0 km of ground.
Around 10,181 people live within 25 km.
When the satellite first saw it
In local solar time the first detection falls at 12:51, 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.
It was seen across 12.7 hours of satellite passes.
36% of the detections came from the night pass.
What this ground has done before
This ground has burned before. Our archive records fire here in 2013, 2016, 2018, 2020, 2022, 2023, 2024, 2026, across 35 days, most recently on 2026-10-10.
Wind and weather
At the fire, wind was 11 km/h from the ESE, carrying smoke and embers towards the WNW. Temperature 38°C, relative humidity 22%.
Twelve hours on, the forecast has wind at 19 km/h from the SE. 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 53rd largest fire burning anywhere on Earth in the current window.
Where analysis would go
Our screening pass scores this fire 0.80. The score ranks where analysis is worth spending.
What the screen noticed: 5 distinct events; activity compressed 13x versus a week-long release; 60% of events first seen at night (local solar), when machinery is not working; events spread over 2 km - too far apart to be one fire, close enough to share an actor; 36 detections per event - large spreading fires, not many ignitions.
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.
