Wildfire near Mahajanga

MadagascarNASA FIRMS (VIIRS)

Recorded by satellite 110 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 76 detections recorded within 20 km of this point since 7 May 2026. The last comparable one was on 11 May 2026. 11 more were recorded here in the fortnight before it.

What the source measured

NASA FIRMS (VIIRS) reported 21 fire pixels with a combined fire radiative power of 266 MW, at high confidence, 51 km from Mahajanga.

The 21 pixels cover about 2.9 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.

Series begins 10 February 2026. Comparisons refer to that period only. Collection gap: 14-26 August 2026.

This data is aggregated algorithmically from scientific sources. Not a replacement for official emergency warnings.
