Hoon fire, 28 March 2024 Hoon
The fire started on 28 March 2024 in Hoon, Laos, and satellites saw it burning for 21 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 2,229 hectares from heat detections, spread across a single municipality.
It is the 196th largest in Oudomxay since 2016 (of 241 with a page). Number 90 in Laos in 2024, of 109.

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
93% of the perimeter overlaps earlier fires recorded since 2016: 223 ha in 2016, 1,107 ha in 2017, 513 ha in 2018, 790 ha in 2019, 1,221 ha in 2020, 1,154 ha in 2021, 1,314 ha in 2022, 1,232 ha in 2023. Part of it burned more than once, so the yearly figures add up to more than the 2,067 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.

The smoke
CAMS · CopernicusOn 8 April 2024 the air beside the fire reached 124 µg/m³ of PM2.5. That day averaged 72: 4.8 times the WHO daily guideline (15).

Frequently asked questions
- How long did the Hoon fire last?
- According to the heat detections seen by satellite inside the perimeter, it burned from 28 March 2024 to 17 April 2024 (21 days). The perimeter dates it from 4 April 2024 to 11 April 2024.
- How much area did it burn?
- The perimeter GWIS (Copernicus) rebuilt from heat detections is 2,229 hectares (22.3 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire only entered Hoon (2,240 ha, 1.1 %).
- 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.
