Thazi fire, March 2023 Yamethin, Pyawbwe, Thazi
The fire started on 4 March 2023 in Thazi, Myanmar, and satellites saw it burning for 11 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 2,307 hectares from heat detections, spread across 3 municipalities.
It is the 53th largest in Mandalay since 2016 (of 69 with a page). Number 182 in Myanmar in 2023, of 240.

This area had burned before
97% of the perimeter overlaps earlier fires recorded since 2016: 2,242 ha in 2016, 2,030 ha in 2017, 1,823 ha in 2018, 2,253 ha in 2019, 2,385 ha in 2020, 1,867 ha in 2021, 222 ha in 2022. Part of it burned more than once, so the yearly figures add up to more than the 2,240 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 0.98 hectares of built-up land and about 250 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 12 March 2023 the air beside the fire reached 99 µg/m³ of PM2.5. That day averaged 62: 4.2 times the WHO daily guideline (15).

Frequently asked questions
- How long did the Thazi fire last?
- According to the heat detections seen by satellite inside the perimeter, it burned from 4 March 2023 to 14 March 2023 (11 days). The perimeter dates it from 8 March 2023 to 11 March 2023.
- How much area did it burn?
- The perimeter GWIS (Copernicus) rebuilt from heat detections is 2,307 hectares (23.1 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire entered 3 municipalities: Yamethin (1,662 ha, 0.8 %); Pyawbwe (414 ha, 0.2 %); Thazi (243 ha, 0.1 %).
- 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 8 March 2023 to 11 March 2023. 69 Suomi-NPP VIIRS detections on those dates.
- We have not matched this page with any official record.
- 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.
