Recorded by satellite today.
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 8th strongest of the 43 detections recorded within 20 km of this point since 15 May 2026. The last comparable one was on 29 August 2026.
What the source measured
NASA FIRMS (VIIRS) reported 67 fire pixels with a combined fire radiative power of 430 MW, at high confidence, 116 km from Tsiroanomandidy.
The 67 pixels cover about 9.4 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.

How we know
One source: NASA FIRMS (VIIRS). Not yet confirmed by a second, independent source.
Our own score for this event is 41 out of 100, at 64 % 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.
