Karimama fire, 28 December 2020 Karimama
Out · last detection 5 Jan 2021, 13:01 UTC
The fire started on 28 December 2020 in Karimama, Benin, and satellites saw it burning for 9 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 6,004 hectares from heat detections, spread across a single municipality.
It is the 19th largest in Alibori since 2016 (of 448 with a page). Number 4 in Benin in 2020, of 94.

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

Inside 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.

It was 4.1 times larger than the median of its twins and lasted 9 days, against 6 days.
Only 1 of its 68 twins burned more. The weather on the first day does not explain everything: the wind in the following days, the fuel and the firefighting also count. In 67 of 68, not even 1 mm fell in the ten days after the end: they went out without rain. In the rest, the first rainy day brought a median of 1.0 mm.

How a twin is chosen
- Same area: fires that have already ended, less than 250 km from this one, since 2016.
- Same start: we compare the FWI on the first day, the minimum humidity that day and the run of days without rain before it. The slider sets how much they may differ.
- Only pages with final weather data (ERA5 reanalysis) calculated in the same way as this fire’s; agricultural and grass burns and pages with data under review are left out.
- Fires burning at the same time as this one (a week before or after) are left out: they share the same spell of weather and do not count as a precedent.
- They are sorted by similarity, and the outlines of the first five are drawn.

Frequently asked questions
- How long did the Karimama fire last?
- According to the heat detections seen by satellite inside the perimeter, it burned from 28 December 2020 to 5 January 2021 (9 days). The perimeter dates it from 28 December 2020 to 3 January 2021.
- How much area did it burn?
- The perimeter GWIS (Copernicus) rebuilt from heat detections is 6,004 hectares (60.0 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire only entered Karimama (6,040 ha, 1.0 %).
- What was the weather like?
- During the fire the temperature reached 38.4 °C, humidity dropped to 12 % and gusts hit 31 km/h. The fire danger index (FWI) reached 52, class Extreme.
- Where does this data come from?
- From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Benin (geoBoundaries). It is not an official report.
- How did the fires that started in similar weather in this area end?
- Fires less than 250 km away that started since 2016 with a similar FWI, humidity and dry spell: 68. Their median duration was 6 days and their median area 1,452 ha; 100 % went past 1,000 ha. Only 1 of its 68 twins burned more. The weather on the first day does not explain everything: the wind in the following days, the fuel and the firefighting also count. In 67 of 68, not even 1 mm fell in the ten days after the end: they went out without rain. In the rest, the first rainy day brought a median of 1.0 mm.
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.
Report an error
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 28 December 2020 to 3 January 2021. 214 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 (Public Domain). 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.
