Beng fire, 6 April 2024 Beng, Xay
The fire started on 6 April 2024 in Beng, Laos, and satellites saw it burning for 3 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 2,024 hectares from heat detections, spread across 2 municipalities.
It is the 232th largest in Oudomxay since 2016 (of 241 with a page). Number 107 in Laos in 2024, of 109.

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: 1,038 ha in 2016, 682 ha in 2017, 651 ha in 2018, 803 ha in 2019, 1,815 ha in 2020, 1,254 ha in 2021, 1,768 ha in 2023. Part of it burned more than once, so the yearly figures add up to more than the 2,033 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 9 April 2024 the air beside the fire reached 150 µg/m³ of PM2.5. That day averaged 102: 6.8 times the WHO daily guideline (15).

Frequently asked questions
- How long did the Beng fire last?
- GWIS (Copernicus) dates it between 6 April 2024 and 8 April 2024: 3 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 2,024 hectares (20.2 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire entered 2 municipalities: Beng (1,964 ha, 1.2 %); Xay (72 ha, 0.0 %).
- 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.
