Mongton fire, 21 March 2026 Mongton, Mongping, Monghsat
The fire started on 21 March 2026 in Mongton, Myanmar, and satellites saw it burning for 25 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 41,742 hectares from heat detections, spread across 3 municipalities.
It is the 4th largest in Shan since 2016 (of 806 with a page). Number 8 in Myanmar in 2026, of 480.

The weather it burned in
It had gone 5 days without rain (1 mm or more) when it started. Rain came after the fire: 7.9 mm on 25 Apr.
This area had burned before
66% of the perimeter overlaps earlier fires recorded since 2016: 5,737 ha in 2016, 8,312 ha in 2017, 3,709 ha in 2018, 6,611 ha in 2019, 6,198 ha in 2020, 5,808 ha in 2021, 3,174 ha in 2022, 11,300 ha in 2023, 3,868 ha in 2024, 4,699 ha in 2025. Part of it burned more than once, so the yearly figures add up to more than the 27,671 ha that had burned before.

Burnt area inside each municipality, from crossing the GWIS perimeter with administrative boundaries. The distance runs from the point marking the centre of each area to the nearest fire: staying a kilometre away does not mean it reached the houses.
People and buildings inside the perimeter
GHSL 2025Inside the perimeter there were about 0.15 hectares of built-up land and about 100 residents (GHSL 2025, satellite-based estimate).
This is an estimate on 100 m cells, made from satellite imagery and census data: it does not mean that homes burned or that anyone was harmed. The perimeter also contains land that never burned. The GHSL 2025 epoch is a projection made from 2020 and earlier data.

The smoke
CAMS · CopernicusOn 27 March 2026 the air beside the fire reached 129 µg/m³ of PM2.5. That day averaged 77: 5.2 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 Mongton fire last?
- GWIS (Copernicus) dates it between 21 March 2026 and 14 April 2026: 25 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 41,742 hectares (417.4 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire entered 3 municipalities: Mongton (22,890 ha, 4.4 %); Mongping (12,880 ha, 2.1 %); Monghsat (6,187 ha, 1.3 %).
- What was the weather like?
- During the fire the temperature reached 35.7 °C, humidity dropped to 23 % and gusts hit 44 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 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.

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; 6 polygons grouped in this page.
- Dates from the perimeter: the VIIRS detections inside it did not change them. 1,516 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.
- Built-up area and population come from the JRC Global Human Settlement Layer (epoch 2025, 100 m cells), summed inside the perimeter: an estimate of what was there, not a damage count.
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.
