Phoukhoune fire, 22 March 2017 Phoukhoune, Xieng Ngeun
The fire started on 22 March 2017 in Phoukhoune, Laos, and satellites saw it burning for 5 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 2,267 hectares from heat detections, spread across 2 municipalities.
It is the 227th largest in Luang Prabang since 2016 (of 293 with a page). Number 86 in Laos in 2017, of 114.

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 Phoukhoune fire last?
- According to the heat detections seen by satellite inside the perimeter, it burned from 22 March 2017 to 26 March 2017 (5 days). The perimeter dates it from 22 March 2017 to 23 March 2017.
- How much area did it burn?
- The perimeter GWIS (Copernicus) rebuilt from heat detections is 2,267 hectares (22.7 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire entered 2 municipalities: Phoukhoune (1,951 ha, 1.2 %); Xieng Ngeun (328 ha, 0.2 %).
- 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.
