Veal Veaeng fire, January 2019 Veal Veaeng
The fire started on 7 January 2019 in Veal Veaeng, Cambodia, and satellites saw it burning for 28 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 4,052 hectares from heat detections, spread across a single municipality.
It is the 6th largest in Pursat since 2016 (of 35 with a page). Number 16 in Cambodia in 2019, of 66.

What happened to each town
-
Veal Veaeng where it started4,080 ha reached on 7 Jan0.9 %
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 2020Inside the perimeter there were about 0.81 hectares of built-up land and about 40 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.

Frequently asked questions
- How long did the Veal Veaeng fire last?
- According to the heat detections seen by satellite inside the perimeter, it burned from 7 January 2019 to 3 February 2019 (28 days). The perimeter dates it from 14 January 2019 to 27 January 2019.
- How much area did it burn?
- The perimeter GWIS (Copernicus) rebuilt from heat detections is 4,052 hectares (40.5 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire only entered Veal Veaeng (4,080 ha, 0.9 %).
- What was the weather like?
- During the fire the temperature reached 35.4 °C, humidity dropped to 26 % and gusts hit 50 km/h. The fire danger index (FWI) reached 35, class High.
- Where does this data come from?
- From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Cambodia (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 14 January 2019 to 27 January 2019. 235 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.
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 ADM2 (Creative Commons Attribution 4.0 International (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.
