Hsihseng fire, January 2026 Hsihseng
The fire started on 14 January 2026 in Hsihseng, Myanmar (Burma), and satellites saw it burning for 15 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 3,099 hectares from heat detections, spread across a single municipality.
It is the 303th largest in Shan since 2016 (of 723 with a page). Number 202 in Myanmar (Burma) in 2026, of 418.
The power measured by the satellite is low (16.4 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 56 days without rain (1 mm or more) when it started.
This area had burned before
97% of the perimeter overlaps earlier fires recorded since 2016: 1,786 ha in 2016, 266 ha in 2017, 933 ha in 2020, 278 ha in 2021, 1,757 ha in 2022, 1,876 ha in 2023, 1,974 ha in 2024, 1,009 ha in 2025. Part of it burned more than once, so the yearly figures add up to more than the 3,002 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.

CAMS · CopernicusOn 30 January 2026 the air beside the fire reached 48 µg/m³ of PM2.5. That day averaged 28: 1.8 times the WHO daily guideline (15).

Frequently asked questions
- How long did the Hsihseng fire last?
- GWIS (Copernicus) dates it between 14 January 2026 and 28 January 2026: 15 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 3,099 hectares (31.0 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire only entered Hsihseng (3,110 ha, 1.5 %).
- What was the weather like?
- During the fire the temperature reached 29.5 °C, humidity dropped to 29 % and gusts hit 24 km/h. The fire danger index (FWI) reached 25, 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.
