Fire near Formosa do Rio Preto, Brazil, 11 October 2026
What the satellites saw
Every pixel VIIRS returned inside 6 km of this fire: 13 in daylight, 8 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 04:27 UTC on 11 October 2026, 19 km SSW of Formosa do Rio Preto in Bahia, Brazil. At its most recent pass it was putting out 697 megawatts of radiative power across 21 separate satellite detections.
The detections span about 2.5 km of ground.
Around 25,857 people live within 25 km.
When the satellite first saw it
In local solar time the first detection falls at 01:26, which is the dead of night. 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 12.9 hours of satellite passes.
38% 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 2012, 2015, 2026, across 20 days, most recently on 2026-10-10.
Wind and weather
At the fire, wind was 9 km/h from the NE, carrying smoke and embers towards the SW. Temperature 25°C, relative humidity 34%.
Twelve hours on, the forecast has wind at 8 km/h from the ESE. These are model figures at roughly 10 km resolution, not a reading taken at the fire.
Where analysis would go
Our screening pass scores this fire 0.65. The score ranks where analysis is worth spending.
What the screen noticed: 27 distinct events in one space-time group; activity compressed 7x versus a week-long release; events spread over 24 km - too far apart to be one fire, close enough to share an actor; 21 detections per event - large spreading fires, not many ignitions.
Read from satellite detections and weather. No roads, no land cover, no ground visit.
