Satellite heat detection 81 km from Luena, Angola

Luma CassaiAngolaNASA FIRMS (VIIRS)

Right now

The most recent data we hold from NASA FIRMS (VIIRS) arrived 14 minutes ago, and this point is not in it. We record detections, not passes: an absence is not proof that nothing is there.

Nothing else has been detected within 20 km in the last 24 hours.

915 satellite detections of this fire · 20 May – 12 August 2026

A satellite sees a burning fire on each of its passes. This page gathers every detection of this fire; the address of each one leads here.

Distance and hazards
Only these hazards

Tick none to hear about every hazard.

One message per event, not per detection. We send a confirmation first, and every message carries a link to stop them. We store the address and the place, nothing else.

Recorded by satellite 93 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 11th strongest of the 57 detections recorded within 20 km of this point since 15 May 2026. The last comparable one was on 23 July 2026. 6 more were recorded here in the fortnight before it.

What the source measured

NASA FIRMS (VIIRS) reported 81 fire pixels with a combined fire radiative power of 908 MW, at high confidence, 81 km from Luena.

The 81 pixels cover about 11.3 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 36 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 “Critical” 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 “Medium”.

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 · Angola

  1. 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.gov
  2. Trapped? 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.gov
  3. Protect 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.

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).
