Santuk fire, February 2018 Santuk

Out · last detection 19 Mar 2018, 18:30 UTC

The fire started on 27 February 2018 in Santuk, Cambodia, and satellites saw it burning for 22 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 4,828 hectares from heat detections, spread across a single municipality.

It is the 6th largest in Kampong Thom since 2016 (of 30 with a page). Number 6 in Cambodia in 2018, of 28.

It had gone 11 days without rain (1 mm or more) when it started. Rain came after the fire: 3.8 mm on 15 Mar.

This area had burned before

77% of the perimeter overlaps earlier fires recorded since 2016: 7,069 ha in 2016, 1,577 ha in 2017. Part of it burned more than once, so the yearly figures add up to more than the 3,716 ha that had burned before.

How big is it?

It burned the equivalent of 3% of the area of London (48 km² against 1,583 km²).

Frequently asked questions

How long did the Santuk fire last?
According to the heat detections seen by satellite inside the perimeter, it burned from 27 February 2018 to 20 March 2018 (22 days). The perimeter dates it from 6 March 2018 to 14 March 2018.
How much area did it burn?
The perimeter GWIS (Copernicus) rebuilt from heat detections is 4,828 hectares (48.3 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire only entered Santuk (4,860 ha, 1.9 %).
What was the weather like?
During the fire the temperature reached 37.3 °C, humidity dropped to 32 % and gusts hit 50 km/h. The fire danger index (FWI) reached 32, 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 6 March 2018 to 14 March 2018. 251 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 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.
