Mongkhet fire, April 2019 Mongkhet, Matman
The fire started on 29 April 2019 in Mongkhet, Myanmar, and satellites saw it burning for 14 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 4,204 hectares from heat detections, spread across 2 municipalities.
It is the 216th largest in Shan since 2016 (of 806 with a page). Number 34 in Myanmar in 2019, of 177.

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.
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.

Frequently asked questions
- How long did the Mongkhet fire last?
- According to the heat detections seen by satellite inside the perimeter, it burned from 29 April 2019 to 12 May 2019 (14 days). The perimeter dates it from 6 May 2019 to 12 May 2019.
- How much area did it burn?
- The perimeter GWIS (Copernicus) rebuilt from heat detections is 4,204 hectares (42.0 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire entered 2 municipalities: Mongkhet (4,210 ha, 1.7 %); Matman (19 ha, 0.0 %).
- What was the weather like?
- During the fire the temperature reached 38.5 °C, humidity dropped to 19 % and gusts hit 43 km/h. The fire danger index (FWI) reached 43, 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.
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 6 May 2019 to 12 May 2019. 131 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.
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.
