Chama fire, 15 October 2026 Chama

Out · last detection 21 Oct 2026, 11:34 UTC

The fire started on 15 October 2026 in Chama, Zambia, and satellites saw it burning for 7 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 4,864 hectares from heat detections, spread across a single municipality.

It is the 246th largest in Muchinga since 2016 (of 516 with a page). Number 234 in Zambia in 2026, of 610.

It had gone 13 days without rain (1 mm or more) when it started.

This area had burned before

66% of the perimeter overlaps earlier fires recorded since 2016: 322 ha in 2016, 640 ha in 2017, 820 ha in 2018, 802 ha in 2019, 303 ha in 2020, 944 ha in 2021, 70 ha in 2023, 579 ha in 2025. Part of it burned more than once, so the yearly figures add up to more than the 3,207 ha that had burned before.

How big is it?

10 km
It burned the equivalent of 3.1% of the area of London (49 km² against 1,583 km²).

Burnt area inside each municipality, from crossing the GWIS perimeter with administrative boundaries. The distance runs from the point marking the centre of each area to the nearest fire: staying a kilometre away does not mean it reached the houses.

Inside the perimeter there was no noticeable built-up land and almost nobody lived there (GHSL 2025, satellite-based estimate).

This is an estimate on 100 m cells, made from satellite imagery and census data: it does not mean that homes burned or that anyone was harmed. The perimeter also contains land that never burned. The GHSL 2025 epoch is a projection made from 2020 and earlier data.

On 13 October 2026 the air beside the fire reached 27 µg/m³ of PM2.5. That day averaged 19: 1.3 times the WHO daily guideline (15).

Frequently asked questions

How long did the Chama fire last?
According to the heat detections seen by satellite inside the perimeter, it burned from 15 October 2026 to 21 October 2026 (7 days). The perimeter dates it from 15 October 2026 to 18 October 2026.
How much area did it burn?
The perimeter GWIS (Copernicus) rebuilt from heat detections is 4,864 hectares (48.6 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire only entered Chama (4,893 ha, 0.3 %).
Is the Chama fire still active?
No fire detections since 21 Oct 2026, 11:34 UTC. A lack of detections is not an official extinction.
What was the weather like?
During the fire the temperature reached 35.8 °C, humidity dropped to 17 % and gusts hit 44 km/h. The fire danger index (FWI) reached 49, class Very high.
Where does this data come from?
From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Zambia (geoBoundaries). It is not an official report.

Where to verify it

A satellite detection is not an official report. Final figures and the fire’s status are published by each country’s emergency service.

Does something look wrong on this page?

This page is built from satellite data and official records, and it sometimes gets things wrong: the wrong dates, the wrong town, two fires merged into one, or something that was not a wildfire at all. If you know this fire first-hand (you live nearby, saw it, fought it or reported on it), tell us what really happened and we will check it.

How we know this
  • Perimeter: GWIS (Copernicus), rebuilt from heat detections rather than mapped on imagery.
  • Dates adjusted with the VIIRS detections inside the perimeter, which said 15 October 2026 to 18 October 2026. 106 Suomi-NPP VIIRS detections on those dates.
  • We have not matched this page with any official record.
  • Weather: Copernicus ERA5 reanalysis at the fire location, in cells of about 25 km.
  • Built-up area and population come from the JRC Global Human Settlement Layer (epoch 2025, 100 m cells), summed inside the perimeter: an estimate of what was there, not a damage count.

Where this data comes from

The perimeter comes from the Copernicus Global Wildfire Information System (GWIS), which rebuilds it from MODIS and VIIRS heat detections and publishes it under CC BY 4.0. It is not measured on imagery as in Europe, so it is an estimate. Heat detections come from the VIIRS sensors aboard Suomi-NPP and NOAA-20, distributed by NASA FIRMS at 375 m resolution. Municipal boundaries come from geoBoundaries ADM2 (Creative Commons Attribution 4.0 (CC BY 4.0)). The area per municipality is computed by WorldFires by crossing the perimeter with those boundaries, so it may differ from each country’s official figure.
