West Gonja fire, 6 January 2022 West Gonja, Sawla-Tuna-Kalba

Out · last detection 14 Jan 2022, 12:49 UTC

The fire started on 6 January 2022 in West Gonja, Ghana, and satellites saw it burning for 9 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 5,003 hectares from heat detections, spread across 2 municipalities.

It is the 46th largest in Savannah since 2016 (of 335 with a page). Number 12 in Ghana in 2022, of 118.

It had gone 56 days without rain (1 mm or more) when it started.

This area had burned before

93% of the perimeter overlaps earlier fires recorded since 2016: 539 ha in 2016, 1,941 ha in 2017, 482 ha in 2018, 3,887 ha in 2019, 2,836 ha in 2020, 187 ha in 2021. Part of it burned more than once, so the yearly figures add up to more than the 4,652 ha that had burned before.

How big is it?

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.

Built-up area< 0.1 ha
Residents< 20

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.

Frequently asked questions

How long did the West Gonja fire last?
According to the heat detections seen by satellite inside the perimeter, it burned from 6 January 2022 to 14 January 2022 (9 days). The perimeter dates it from 8 January 2022 to 11 January 2022.
How much area did it burn?
The perimeter GWIS (Copernicus) rebuilt from heat detections is 5,003 hectares (50.0 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire entered 2 municipalities: West Gonja (3,580 ha, 0.8 %); Sawla-Tuna-Kalba (1,456 ha, 0.3 %).
What was the weather like?
During the fire the temperature reached 35.2 °C, humidity dropped to 11 % and gusts hit 32 km/h. The fire danger index (FWI) reached 48, class Very high.
Where does this data come from?
From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Ghana (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 8 January 2022 to 11 January 2022. 145 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 (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.
