Lumphat fire, January 2020 Lumphat

Out · last detection 21 Jan 2020, 18:10 UTC

The fire started on 9 January 2020 in Lumphat, Cambodia, and satellites saw it burning for 12 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 2,061 hectares from heat detections, spread across a single municipality.

It is the 72th largest in Ratanakiri since 2016 (of 79 with a page). Number 76 in Cambodia in 2020, of 78.

This area had burned before

90% of the perimeter overlaps earlier fires recorded since 2016: 1,796 ha in 2016, 1,386 ha in 2017, 748 ha in 2018, 320 ha in 2019. Part of it burned more than once, so the yearly figures add up to more than the 1,856 ha that had burned before.

How big is it?

10 km
It burned the equivalent of 1.3% of the area of London (21 km² against 1,583 km²).

Burnt area inside each municipality, from crossing the GWIS perimeter with administrative boundaries. The distance is from the town centre to the nearest fire: staying a kilometre away does not mean it reached the houses.

Frequently asked questions

How long did the Lumphat fire last?
GWIS (Copernicus) dates it between 9 January 2020 and 20 January 2020: 12 days between the first and last heat detection of the perimeter.
How much area did it burn?
The perimeter GWIS (Copernicus) rebuilt from heat detections is 2,061 hectares (20.6 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire only entered Lumphat (2,073 ha, 1.1 %).
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.

Satellite cross-check

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 from the perimeter: the VIIRS detections inside it did not change them. 123 Suomi-NPP VIIRS detections on those dates.
  • We have not matched this page with any official record.

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 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.
