Recorded by satellite 75 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.
It is the 27th strongest of the 524 detections recorded within 20 km of this point since 6 March 2024. The last comparable one was on 16 June 2026. 3 more were recorded here in the fortnight before it.
What the source measured
NASA FIRMS (VIIRS) reported 17 fire pixels with a combined fire radiative power of 135 MW, at nominal confidence, 14 km from San Clemente.
The 17 pixels cover about 2.4 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.
An estimated 20,860 people live within 20 km of this point.

How we know
One source: NASA FIRMS (VIIRS). Not yet confirmed by a second, independent source.
Our own score for this event is 39 out of 100, at 74 % 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.
