Thateng fire, March 2020 Thateng
The fire started on 21 March 2020 in Thateng, Laos, and satellites saw it burning for 11 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 2,005 hectares from heat detections, spread across a single municipality.
It is the 22th largest in Xekong since 2016 (of 22 with a page). Number 166 in Laos in 2020, of 169.

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
57% of the perimeter overlaps earlier fires recorded since 2016: 690 ha in 2018, 634 ha in 2019. Part of it burned more than once, so the yearly figures add up to more than the 1,151 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.

Frequently asked questions
- How long did the Thateng fire last?
- According to the heat detections seen by satellite inside the perimeter, it burned from 21 March 2020 to 31 March 2020 (11 days). The perimeter dates it from 21 March 2020 to 27 March 2020.
- How much area did it burn?
- The perimeter GWIS (Copernicus) rebuilt from heat detections is 2,005 hectares (20.0 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire only entered Thateng (2,018 ha, 3.0 %).
- 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.
