Out · last detection 20 Feb 2026, 06:22 UTC

The fire started on 2 February 2026 in Sukhuma, Laos, and satellites saw it burning for 20 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 2,992 hectares from heat detections, spread across 2 municipalities.

It is the 9th largest in Champasak since 2016 (of 22 with a page). Number 166 in Laos in 2026, of 308.

It had gone 49 days without rain (1 mm or more) when it started. Rain came after the fire: 7.1 mm on 27 Feb.

This area had burned before

15% of the perimeter overlaps earlier fires recorded since 2016: 13 ha in 2016, 416 ha in 2017, 70 ha in 2021, 60 ha in 2022, 245 ha in 2023, 85 ha in 2024. Part of it burned more than once, so the yearly figures add up to more than the 448 ha that had burned before.

How big is it?

10 km
It burned the equivalent of 1.9% of the area of London (30 km² against 1,583 km²).

Frequently asked questions

How long did the Sukhuma fire last?
According to the heat detections seen by satellite inside the perimeter, it burned from 2 February 2026 to 21 February 2026 (20 days). The perimeter dates it from 8 February 2026 to 21 February 2026.
How much area did it burn?
The perimeter GWIS (Copernicus) rebuilt from heat detections is 2,992 hectares (29.9 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire entered 2 municipalities: Moonlapamok (2,266 ha, 1.0 %); Sukhuma (745 ha, 0.7 %).
What was the weather like?
During the fire the temperature reached 36.9 °C, humidity dropped to 31 % and gusts hit 30 km/h. The fire danger index (FWI) reached 31, class High.
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.

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 8 February 2026 to 21 February 2026. 70 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.

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.
