Mongton fire, 28 March 2025 Mongton
The fire started on 28 March 2025 in Mongton, Myanmar, and satellites saw it burning for 6 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 2,620 hectares from heat detections, spread across a single municipality.
It is the 486th largest in Shan since 2016 (of 806 with a page). Number 86 in Myanmar in 2025, of 135.

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.
The weather it burned in
It had gone 30 days without rain (1 mm or more) when it started. Rain came after the fire: 1.5 mm on 12 Apr.
This area had burned before
94% of the perimeter overlaps earlier fires recorded since 2016: 447 ha in 2016, 152 ha in 2017, 2,053 ha in 2019, 1,112 ha in 2020, 734 ha in 2021, 23 ha in 2022, 1,188 ha in 2023, 514 ha in 2024. Part of it burned more than once, so the yearly figures add up to more than the 2,457 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 weather day by day
ECMWF ERA5 reanalysis at the fire location, the standard reference for past weather, and the Canadian Fire Weather Index (the same system Copernicus uses), computed by WorldFires from that data. Days after the fire run until the first rain.

The smoke
CAMS · CopernicusOn 30 March 2025 the air beside the fire reached 104 µg/m³ of PM2.5. That day averaged 76: 5.1 times the WHO daily guideline (15).

Frequently asked questions
- How long did the Mongton fire last?
- GWIS (Copernicus) dates it between 28 March 2025 and 2 April 2025: 6 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 2,620 hectares (26.2 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire only entered Mongton (2,637 ha, 0.5 %).
- What was the weather like?
- During the fire the temperature reached 37.5 °C, humidity dropped to 12 % and gusts hit 38 km/h. The fire danger index (FWI) reached 41, class Very high.
- Where does this data come from?
- From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Myanmar (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.
Report an error
How we know this
- Perimeter: GWIS (Copernicus), rebuilt from heat detections rather than mapped on imagery.
- Dates from the perimeter: the VIIRS detections inside it did not change them. 72 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 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.
