Paletwa fire, 25 March 2022 Paletwa

Out · last detection 12 Apr 2022, 06:56 UTC

The fire started on 25 March 2022 in Paletwa, Myanmar, and satellites saw it burning for 19 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 4,418 hectares from heat detections, spread across a single municipality.

It is the 51th largest in Chin since 2016 (of 209 with a page). Number 14 in Myanmar in 2022, of 77.

It had gone one day without rain (1 mm or more) when it started. Rain came after the fire: 1.5 mm on 22 Apr.

This area had burned before

93% of the perimeter overlaps earlier fires recorded since 2016: 1,954 ha in 2016, 952 ha in 2017, 1,187 ha in 2018, 2,195 ha in 2019, 3,341 ha in 2020, 3,380 ha in 2021. Part of it burned more than once, so the yearly figures add up to more than the 4,112 ha that had burned before.

How big is it?

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

Built-up area0.19 ha
Residents≈ 250

Inside the perimeter there were about 0.19 hectares of built-up land and about 250 residents (GHSL 2020, 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.

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 Paletwa fire last?
According to the heat detections seen by satellite inside the perimeter, it burned from 25 March 2022 to 12 April 2022 (19 days). The perimeter dates it from 31 March 2022 to 5 April 2022.
How much area did it burn?
The perimeter GWIS (Copernicus) rebuilt from heat detections is 4,418 hectares (44.2 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire only entered Paletwa (4,443 ha, 0.6 %).
What was the weather like?
During the fire the temperature reached 39.8 °C, humidity dropped to 27 % and gusts hit 43 km/h. The fire danger index (FWI) reached 36, 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.
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: 27. Their median duration was 10 days and their median area 3,056 ha; 100 % went past 1,000 ha. In 14 of 27, 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 1.7 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 31 March 2022 to 5 April 2022. 169 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 2020, 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.
