Monghsu fire, 20 March 2026 Monghsu
The fire started on 20 March 2026 in Monghsu, Myanmar (Burma), and satellites saw it burning for 12 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 2,273 hectares from heat detections, spread across a single municipality.
It is the 568th largest in Shan since 2016 (of 723 with a page). Number 331 in Myanmar (Burma) in 2026, of 418.

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
72% of the perimeter overlaps earlier fires recorded since 2016: 1,192 ha in 2018, 913 ha in 2020, 20 ha in 2023. Part of it burned more than once, so the yearly figures add up to more than the 1,641 ha that had burned before.
What happened to each town

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 28 March 2026 the air beside the fire reached 113 µg/m³ of PM2.5. That day averaged 66: 4.4 times the WHO daily guideline (15).
Particles from the Copernicus CAMS model at the centre of the perimeter; these are not measurements in each town. The pale bar is the worst hour, the solid one the daily average.

Frequently asked questions
- How long did the Monghsu fire last?
- GWIS (Copernicus) dates it between 20 March 2026 and 31 March 2026: 12 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 2,273 hectares (22.7 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire only entered Monghsu (2,282 ha, 1.4 %).
- Where does this data come from?
- From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Myanmar (Burma) (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 ADM3 (Creative Commons Attribution 4.0 (CC BY 4.0)). 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.
