Recorded by satellite 166 days ago.
A thermal anomaly is a snapshot of one satellite pass, not a record of a fire’s life: we cannot say whether it kept burning after that pass.
No stronger detection stands among the 5 recorded within 20 km of this point since 17 March 2026 — one other scored the same. The last comparable one was on 17 March 2026. 2 more were recorded here in the fortnight before it.
What the source measured
NASA FIRMS (VIIRS) reported 16 fire pixels with a combined fire radiative power of 151 MW, at nominal confidence, 59 km from Cáceres.
The 16 pixels cover about 2.2 km² — that is the footprint of the detection grid at 375 m resolution, not an estimate of how much land burned.
FIRMS does not report burned area, and neither do we.

How we know
One source: NASA FIRMS (VIIRS). Not yet confirmed by a second, independent source.
Our own score for this event is 32 out of 100, at 38 % confidence.
The score is ours, computed from intensity, exposed population and local history — not the source’s.

Safety Information
If a wildfire is approaching: follow evacuation orders immediately. Do not wait to see the fire. Close all windows and doors, remove combustible materials from around your home, and have an emergency go-bag ready. Air quality can deteriorate rapidly even at distance from the fire front — monitor local air quality advisories.
