Wundwin fire, February 2026 Ywangan, Wundwin, Thazi

Out · last detection 8 Mar 2026, 18:54 UTC

The fire started on 10 February 2026 in Wundwin, Myanmar (Burma), and satellites saw it burning for 26 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 17,461 hectares from heat detections, spread across 3 municipalities.

It is the largest fire in Mandalay since 2016 (of 72 with a page). Number 21 in Myanmar (Burma) in 2026, of 418.

The power measured by the satellite is low (24.0 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 more than two months without rain (1 mm or more) when it started.

This area had burned before

38% of the perimeter overlaps earlier fires recorded since 2016: 3,082 ha in 2017, 1,697 ha in 2019, 1,886 ha in 2023, 756 ha in 2024. Part of it burned more than once, so the yearly figures add up to more than the 6,659 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.

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.

Frequently asked questions

How long did the Wundwin fire last?
GWIS (Copernicus) dates it between 10 February 2026 and 7 March 2026: 26 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 17,461 hectares (174.6 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire entered 3 municipalities: Ywangan (13,683 ha, 4.6 %); Wundwin (2,851 ha, 2.0 %); Thazi (994 ha, 0.5 %).
What was the weather like?
During the fire the temperature reached 30.7 °C, humidity dropped to 26 % and gusts hit 37 km/h. The fire danger index (FWI) reached 28, class High.
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.
