Recorded by satellite 167 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 4th strongest of the 7 detections recorded within 20 km of this point since 16 March 2026. The last comparable one was on 17 March 2026. 5 more were recorded here in the fortnight before it.
What the source measured
NASA FIRMS (VIIRS) reported 65 fire pixels with a combined fire radiative power of 483 MW, at high confidence, 54 km from Muang Phônsavan.
The 65 pixels cover about 9.1 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.

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.
