Khlong Lan fire, 13 March 2024 คลองลาน · Khlong Lan, Pang Sila Thong
The fire started on 13 March 2024 in Khlong Lan, Thailand, and satellites saw it burning for 6 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 1,801 hectares from heat detections, spread across 2 municipalities.
It is the 33th largest in Kamphaeng Phet Province since 2016 (of 65 with a page). Number 97 in Thailand in 2024, of 277.
The power measured by the satellite is low (8.4 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

Where it burned
How it evolved, day by day
Fire radiative power detected each day, in megawatts, and number of hotspots. The magenta bar marks the peak day.
The weather it burned in
It had gone 4 days without rain (1 mm or more) when it started. Rain came after the fire: 2.6 mm on 19 Mar.
This area had burned before
92% of the perimeter overlaps earlier fires recorded since 2016: 141 ha in 2016, 496 ha in 2017, 1,159 ha in 2019, 870 ha in 2020, 1,150 ha in 2021, 1,599 ha in 2023. Part of it burned more than once, so the yearly figures add up to more than the 1,660 ha that had burned before.

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 2025Inside 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.

The smoke
CAMS · CopernicusOn 18 March 2024 the air beside the fire reached 74 µg/m³ of PM2.5. That day averaged 55: 3.7 times the WHO daily guideline (15).

Frequently asked questions
- How long did the Khlong Lan fire last?
- According to the heat detections seen by satellite inside the perimeter, it burned from 13 March 2024 to 18 March 2024 (6 days). The perimeter dates it from 13 March 2024 to 16 March 2024.
- How much area did it burn?
- The perimeter GWIS (Copernicus) rebuilt from heat detections is 1,801 hectares (18.0 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire entered 2 municipalities: Khlong Lan (1,672 ha, 1.1 %); Pang Sila Thong (137 ha, 0.2 %).
- What was the weather like?
- During the fire the temperature reached 35.4 °C, humidity dropped to 30 % and gusts hit 33 km/h. The fire danger index (FWI) reached 26, class High.
- Where does this data come from?
- From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Thailand (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 13 March 2024 to 16 March 2024. 58 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.
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 3.0 Intergovernmental Organisations (CC BY 3.0 IGO)). 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.
