Mongpan fire, 21 March 2026 Mongpan

Out · last detection 30 Mar 2026, 18:42 UTC

The fire started on 21 March 2026 in Mongpan, Myanmar, and satellites saw it burning for 9 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 3,854 hectares from heat detections, spread across a single municipality.

It is the 237th largest in Shan since 2016 (of 806 with a page). Number 183 in Myanmar in 2026, of 480.

The power measured by the satellite is low (10.0 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

It had gone 6 days without rain (1 mm or more) when it started.

This area had burned before

55% of the perimeter overlaps earlier fires recorded since 2016: 227 ha in 2017, 278 ha in 2019, 145 ha in 2020, 134 ha in 2022, 879 ha in 2023, 258 ha in 2024, 1,488 ha in 2025. Part of it burned more than once, so the yearly figures add up to more than the 2,125 ha that had burned before.

How big is it?

10 km
It burned the equivalent of 2.4% of the area of London (39 km² against 1,583 km²).

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.

Frequently asked questions

How long did the Mongpan fire last?
GWIS (Copernicus) dates it between 21 March 2026 and 29 March 2026: 9 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 3,854 hectares (38.5 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire only entered Mongpan (3,871 ha, 1.4 %).
What was the weather like?
During the fire the temperature reached 36.8 °C, humidity dropped to 22 % and gusts hit 49 km/h. The fire danger index (FWI) reached 35, 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.
  • Dates from the perimeter: the VIIRS detections inside it did not change them. 73 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.
