Arauca fire, 25 March 2020 Arauca, Arauquita
The fire started on 25 March 2020 in Arauca, Colombia, and satellites saw it burning for 13 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 2,040 hectares from heat detections, spread across 2 municipalities.
It is the 73th largest in Arauca since 2016 (of 107 with a page). Number 93 in Colombia in 2020, of 158.

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 was no noticeable built-up land and almost nobody lived there (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.

Official record
According to UNGRD, a fire of 1,000 ha was recorded in Arauca on 25 March 2020 (the satellite measured 2,040 ha). The record has no coordinates, so it was matched by municipality and date. The two figures differ a lot, so these may not be exactly the same fire: take them as nearby records.

Frequently asked questions
- How long did the Arauca fire last?
- According to the heat detections seen by satellite inside the perimeter, it burned from 25 March 2020 to 6 April 2020 (13 days). The perimeter dates it from 25 March 2020 to 31 March 2020.
- How much area did it burn?
- The perimeter GWIS (Copernicus) rebuilt from heat detections is 2,040 hectares (20.4 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire entered 2 municipalities: Arauca (1,238 ha, 0.2 %); Arauquita (816 ha, 0.3 %).
- What was the weather like?
- During the fire the temperature reached 37.5 °C, humidity dropped to 25 % and gusts hit 37 km/h. The fire danger index (FWI) reached 40, class Very high.
- Where does this data come from?
- From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Colombia (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 25 March 2020 to 31 March 2020. 156 Suomi-NPP VIIRS detections on those dates.
- Compared with UNGRD: 1,000 official ha against 2,040 ha of perimeter; similar, but with reservations.
- 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.
