Karimama fire, 17 February 2017 Karimama

Out · last detection 22 Feb 2017, 12:55 UTC

The fire started on 17 February 2017 in Karimama, Benin, and satellites saw it burning for 6 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 3,850 hectares from heat detections, spread across a single municipality.

It is the 68th largest in Alibori since 2016 (of 534 with a page). Number 16 in Benin in 2017, of 152.

The power measured by the satellite is low (16.5 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

Frequently asked questions

How long did the Karimama fire last?
According to the heat detections seen by satellite inside the perimeter, it burned from 17 February 2017 to 22 February 2017 (6 days). The perimeter dates it from 17 February 2017 to 21 February 2017.
How much area did it burn?
The perimeter GWIS (Copernicus) rebuilt from heat detections is 3,850 hectares (38.5 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire only entered Karimama (3,879 ha, 0.6 %).
What was the weather like?
During the fire the temperature reached 37.0 °C, humidity dropped to 6 % and gusts hit 45 km/h. The fire danger index (FWI) reached 69, 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.

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 adjusted with the VIIRS detections inside the perimeter, which said 17 February 2017 to 21 February 2017. 110 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 (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.
