Pinlaung fire, January 2021 Nyaungshwe, Pinlaung

Out · last detection 25 Jan 2021, 19:12 UTC

The fire started on 9 January 2021 in Pinlaung, Myanmar, and satellites saw it burning for 17 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 5,187 hectares from heat detections, spread across 2 municipalities.

It is the 95th largest in Shan since 2016 (of 625 with a page). Number 32 in Myanmar in 2021, of 190.

It had gone more than two months without rain (1 mm or more) when it started. Rain came after the fire: 1.2 mm on 30 Jan.

This area had burned before

92% of the perimeter overlaps earlier fires recorded since 2016: 25 ha in 2016, 1,403 ha in 2017, 3,829 ha in 2019, 3,913 ha in 2020. Part of it burned more than once, so the yearly figures add up to more than the 4,790 ha that had burned before.

How big is it?

It burned the equivalent of 3.3% of the area of London (52 km² against 1,583 km²).

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.

Built-up area1.0 ha
Residents≈ 400

Inside the perimeter there were about 1.0 hectares of built-up land and about 400 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.

Its twins: fires that started in the same weather

It started with an FWI of 22.6, a minimum humidity of 48% and more than two months without rain. Fires in the area that started in weather like this since 2016: 24.

It was 1.7 times larger than the median of its twins and lasted 17 days, against 13 days.

Only 3 of its 24 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 10 of 24, 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 1.3 mm.

It was considered over on 25 Jan, and on 30 Jan 1.2 mm fell. We do not know whether the rain or the firefighters put it out. Twins with rain when they ended: 14 of 24, with a median of 1.3 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 Pinlaung fire last?
According to the heat detections seen by satellite inside the perimeter, it burned from 9 January 2021 to 25 January 2021 (17 days). The perimeter dates it from 14 January 2021 to 24 January 2021.
How much area did it burn?
The perimeter GWIS (Copernicus) rebuilt from heat detections is 5,187 hectares (51.9 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire entered 2 municipalities: Nyaungshwe (4,782 ha, 3.2 %); Pinlaung (422 ha, 0.1 %).
What was the weather like?
During the fire the temperature reached 30.6 °C, humidity dropped to 35 % and gusts hit 38 km/h. The fire danger index (FWI) reached 23, 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: 24. Their median duration was 13 days and their median area 3,002 ha; 100 % went past 1,000 ha. Only 3 of its 24 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 10 of 24, 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 1.3 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 14 January 2021 to 24 January 2021. 159 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.
