Bandafassi fire, 13 January 2021 Bandafassi

Out · last detection 17 Jan 2021, 14:17 UTC

The fire started on 13 January 2021 in Bandafassi, Senegal, and satellites saw it burning for 4 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 4,378 hectares from heat detections, spread across a single municipality.

It is the 37th largest in Kédougou since 2016 (of 116 with a page). Number 17 in Senegal in 2021, of 73.

It had gone more than two months without rain (1 mm or more) when it started.

This area had burned before

94% of the perimeter overlaps earlier fires recorded since 2016: 734 ha in 2016, 3,685 ha in 2017, 1,525 ha in 2018, 2,128 ha in 2020. Part of it burned more than once, so the yearly figures add up to more than the 4,107 ha that had burned before.

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.

The weather day by day

ECMWF ERA5 reanalysis at the fire location, the standard reference for past weather, and the Canadian Fire Weather Index (the same system Copernicus uses), computed by WorldFires from that data. Days after the fire run until the first rain.

Frequently asked questions

How long did the Bandafassi fire last?
GWIS (Copernicus) dates it between 13 January 2021 and 16 January 2021: 4 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 4,378 hectares (43.8 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire only entered Bandafassi (4,408 ha, 0.8 %).
What was the weather like?
During the fire the temperature reached 38.5 °C, humidity dropped to 10 % and gusts hit 39 km/h. The fire danger index (FWI) reached 58, class Extreme.
Where does this data come from?
From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Senegal (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.

Emergency number: 18

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.

We will only use your email to reply about this report. Privacy. This is not an emergency service: if there is a fire now, call 18.

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 ADM3 (Creative Commons Attribution 3.0 Intergovernmental Organisations (CC BY 3.0 IGO)). 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.
