Satellite heat detection near Ankazobe, Madagascar
Right now
The most recent data we hold from NASA FIRMS (VIIRS) arrived 1 minute ago, and this point is not in it. We record detections, not passes: an absence is not proof that nothing is there.
3 other detections within 20 km in the last 24 hours, the nearest 8 km from here.
42 satellite detections of this fire · 25 July – 13 August 2026

This page covers the record dated 25 July 2026. Browse recent observations in this area:
Recorded by satellite 94 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 2nd strongest of the 13 detections recorded within 20 km of this point since 13 May 2026. The last comparable one was on 22 July 2026. One more was recorded here in the fortnight before it.
What the source measured
NASA FIRMS (VIIRS) reported 35 fire pixels with a combined fire radiative power of 221 MW, at high confidence, 23 km from Ankazobe.
The 35 pixels cover about 4.9 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.
Urban PEI: 9,486 within a heuristic 35 km radius; not unique people.

How we know
One source: NASA FIRMS (VIIRS). Not yet confirmed by a second, independent source.
Our own score for this event is 35 out of 100.
This is our versioned heuristic index, not source severity or a calibrated probability. Urban PEI does not count unique people.
Computed under scoring rules v1. Rows carrying other versions were judged by different rules and are not directly comparable.
Archived as “High” under the rule in force until 4 October 2026, which read the radiative power and the people nearby. A satellite sees heat, not an emergency: since then every detection is shown as low or medium; this one as “Low”.
Series begins 8 March 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.

Safety information
What to do near a wildfire
A satellite saw heat here. It cannot tell a wildfire from a controlled burn or an industrial flame, and it sees nothing under thick cloud. If you see smoke or flames, call the local emergency number and follow the fire service. Evacuation orders come from local authorities, not from this page.
For this reportSatellite heat detection · Ankazobe
Leave when told, early
When authorities order an evacuation, go at once. Do not wait to see the flames: fire moves faster than you can run.
Ready.govTrapped? Call for help
Call the emergency number and give your location. Stay in a building or a car rather than in the open, with doors and windows shut.
Ready.govProtect yourself from smoke
Stay indoors with windows closed, use an air purifier if you have one, and wear an N95/FFP2 mask outside.

Before, during, after. Here it is “after”.
Before · In fire season
Get the alerts
Official alerts on your phone, so an evacuation order reaches you.
Plan two ways out
Know two routes away from home and practise them.
Clear around the house
Remove dry leaves, wood and anything that burns from around the walls.
A bag by the door
Documents, medicines, chargers, masks, water.
Ready.gov (FEMA)
During · While the fire is near
Go at once if ordered
Follow the routes authorities give.
Shut the smoke out
Close windows and doors; set the air conditioning to recirculate.
Keep outdoor effort low
Smoke harms lungs and heart, most of all in children, older people and those with asthma.
Ready.gov (FEMA) · AirNow
After · When the fire has passed
Return when it is declared safe
Roads, trees and power lines can still be dangerous.
Beware hot spots
Ash and the ground can stay hot enough to burn for days.
Clean up protected
Gloves, long sleeves, sturdy shoes and a mask; wet the ash before moving it.

If a life is in danger
Call your local emergency number
Questions people ask
Does a satellite detection mean a wildfire?
Not always. A satellite sees heat: a wildfire, a controlled burn, a flare or an industrial plant. If you see smoke or flames, call the local emergency number and follow the fire service.
Do cloth masks protect from smoke?
Not much. A well-fitting N95 (FFP2 in Europe) filters the fine particles; cloth and surgical masks let most of them through. Source: AirNow (US EPA).
When can I go home?
Only when authorities say the area is safe. Source: Ready.gov (FEMA).
