Hpasawng fire, 24 February 2024 Hpasawng, Hpapun

Out · last detection 7 Mar 2024, 18:54 UTC

The fire started on 24 February 2024 in Hpasawng, Myanmar, and satellites saw it burning for 18 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 3,717 hectares from heat detections, spread across 2 municipalities.

It is the 55th largest in Kayah since 2016 (of 169 with a page). Number 58 in Myanmar in 2024, of 174.

The power measured by the satellite is low (15.2 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 26 days without rain (1 mm or more) when it started. Rain came after the fire: 7.9 mm on 21 Mar.

This area had burned before

91% of the perimeter overlaps earlier fires recorded since 2016: 1,600 ha in 2016, 2,003 ha in 2017, 2 ha in 2018, 1,117 ha in 2019, 1,230 ha in 2020, 116 ha in 2021, 2 ha in 2022, 1,116 ha in 2023. Part of it burned more than once, so the yearly figures add up to more than the 3,390 ha that had burned before.

Inside the perimeter there was no noticeable built-up land and almost nobody lived there (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.

Its twins: fires that started in the same weather

It started with an FWI of 22.8, a minimum humidity of 35% and 26 days without rain. Fires in the area that started in weather like this since 2016: 21.

It was 1.8 times larger than the median of its twins and lasted 18 days, against 14 days.

Only 5 of its 21 twins burned more. The weather on the first day does not explain everything: the wind in the following days, the fuel and the firefighting also count. In 15 of 21, not even 1 mm fell in the ten days after the end: they went out without rain. In the rest, the first rainy day brought a median of 3.4 mm.

How a twin is chosen

  • Same area: fires that have already ended, less than 250 km from this one, since 2016.
  • Same start: we compare the FWI on the first day, the minimum humidity that day and the run of days without rain before it. The slider sets how much they may differ.
  • Only pages with final weather data (ERA5 reanalysis) calculated in the same way as this fire’s; agricultural and grass burns and pages with data under review are left out.
  • Fires burning at the same time as this one (a week before or after) are left out: they share the same spell of weather and do not count as a precedent.
  • They are sorted by similarity, and the outlines of the first five are drawn.

Frequently asked questions

How long did the Hpasawng fire last?
According to the heat detections seen by satellite inside the perimeter, it burned from 24 February 2024 to 12 March 2024 (18 days). The perimeter dates it from 26 February 2024 to 5 March 2024.
How much area did it burn?
The perimeter GWIS (Copernicus) rebuilt from heat detections is 3,717 hectares (37.2 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire entered 2 municipalities: Hpasawng (3,686 ha, 2.6 %); Hpapun (48 ha, 0.0 %).
What was the weather like?
During the fire the temperature reached 36.7 °C, humidity dropped to 27 % and gusts hit 44 km/h. The fire danger index (FWI) reached 40, 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.
How did the fires that started in similar weather in this area end?
Fires less than 250 km away that started since 2016 with a similar FWI, humidity and dry spell: 21. Their median duration was 14 days and their median area 2,100 ha; 100 % went past 1,000 ha. Only 5 of its 21 twins burned more. The weather on the first day does not explain everything: the wind in the following days, the fuel and the firefighting also count. In 15 of 21, not even 1 mm fell in the ten days after the end: they went out without rain. In the rest, the first rainy day brought a median of 3.4 mm.

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 26 February 2024 to 5 March 2024. 155 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.
  • 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.

How we build fire pages: methodology

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.
