Pale fire, February 2025 Pale, Yinmarbin
The fire started on 25 February 2025 in Pale, Myanmar, and satellites saw it burning for 21 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 2,993 hectares from heat detections, spread across 2 municipalities.
It is the 45th largest in Saigang since 2016 (of 100 with a page). Number 69 in Myanmar in 2025, of 135.
The power measured by the satellite is low (14.8 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

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 more than two months without rain (1 mm or more) when it started.
This area had burned before
73% of the perimeter overlaps earlier fires recorded since 2016: 1,069 ha in 2023, 1,288 ha in 2024. Part of it burned more than once, so the yearly figures add up to more than the 2,170 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.
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.

CAMS · CopernicusOn 3 March 2025 the air beside the fire reached 77 µg/m³ of PM2.5. That day averaged 57: 3.8 times the WHO daily guideline (15).

Frequently asked questions
- How long did the Pale fire last?
- According to the heat detections seen by satellite inside the perimeter, it burned from 25 February 2025 to 17 March 2025 (21 days). The perimeter dates it from 3 March 2025 to 10 March 2025.
- How much area did it burn?
- The perimeter GWIS (Copernicus) rebuilt from heat detections is 2,993 hectares (29.9 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire entered 2 municipalities: Pale (2,859 ha, 1.8 %); Yinmarbin (150 ha, 0.2 %).
- What was the weather like?
- During the fire the temperature reached 37.3 °C, humidity dropped to 16 % and gusts hit 29 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.

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 3 March 2025 to 10 March 2025. 137 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.
