Kham fire, 14 March 2026 Kham
The fire started on 14 March 2026 in Kham, Laos, and satellites saw it burning for 4 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 2,459 hectares from heat detections, spread across a single municipality.
It is the 79th largest in Xiangkhouang since 2016 (of 107 with a page). Number 203 in Laos in 2026, of 287.
The power measured by the satellite is low (19.8 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

Where it burned
How it evolved, day by day
Fire radiative power detected each day, in megawatts, and number of hotspots. The magenta bar marks the peak day.
This area had burned before
100% of the perimeter overlaps earlier fires recorded since 2016: 424 ha in 2016, 763 ha in 2017, 1,803 ha in 2018, 597 ha in 2019, 1,549 ha in 2020, 890 ha in 2022, 1,981 ha in 2023, 571 ha in 2024, 2,156 ha in 2025. Part of it burned more than once, so the yearly figures add up to more than the 2,472 ha that had burned before.

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

If the day is cloudy, change the date: each satellite passes once a day. In false colour the burnt ground looks brown or red.
The smoke
CAMS · CopernicusOn 12 March 2026 the air beside the fire reached 58 µg/m³ of PM2.5. That day averaged 37: 2.5 times the WHO daily guideline (15).

Frequently asked questions
- How long did the Kham fire last?
- GWIS (Copernicus) dates it between 14 March 2026 and 17 March 2026: 4 days between the first and last heat detection of the perimeter.
- How much area did it burn?
- The perimeter GWIS (Copernicus) rebuilt from heat detections is 2,459 hectares (24.6 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire only entered Kham (2,471 ha, 1.2 %).
- Where does this data come from?
- From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Laos (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.
Satellite cross-check
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.

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 3.0 Intergovernmental Organisations (CC BY 3.0 IGO)). 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.
