Fire near Floriano, Brazil, 10 October 2026

What the satellites saw
Every pixel VIIRS returned inside 6 km of this fire: 5 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 16:01 UTC on 10 October 2026, 18 km SSW of Floriano in Piauí, Brazil. At its most recent pass it was putting out 21 megawatts of radiative power across 5 separate satellite detections.
The detections span about 1.0 km of ground.
Around 81,020 people live within 25 km.
When the satellite first saw it
In local solar time the first detection falls at 13:09, 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, 2017, 2018, 2019, 2021, 2023, 2025, 2026, across 30 days, most recently on 2026-10-09.
Wind and weather
At the fire, wind was 7 km/h from the SE, carrying smoke and embers towards the NW. Temperature 37°C, relative humidity 24%.
Twelve hours on, the forecast has wind at 12 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 0.70. The score ranks where analysis is worth spending.
What the screen noticed: 9 distinct events in one space-time group; activity compressed 14x versus a week-long release; events spread over 21 km - too far apart to be one fire, close enough to share an actor.
