Shiroro fire, 30 November 2023 Shiroro

Out · last detection 17 Dec 2023, 13:26 UTC

The fire started on 30 November 2023 in Shiroro, Nigeria, and satellites saw it burning for 21 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 2,453 hectares from heat detections, spread across a single municipality.

It is the 206th largest in Niger since 2016 (of 271 with a page). Number 109 in Nigeria in 2023, of 164.

The power measured by the satellite is low (28.3 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 Shiroro fire last?
According to the heat detections seen by satellite inside the perimeter, it burned from 30 November 2023 to 20 December 2023 (21 days). The perimeter dates it from 6 December 2023 to 13 December 2023.
How much area did it burn?
The perimeter GWIS (Copernicus) rebuilt from heat detections is 2,453 hectares (24.5 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire only entered Shiroro (2,470 ha, 0.5 %).
What was the weather like?
During the fire the temperature reached 35.1 °C, humidity dropped to 17 % and gusts hit 48 km/h. The fire danger index (FWI) reached 49, class Very high.
Where does this data come from?
From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Nigeria (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 6 December 2023 to 13 December 2023. 87 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 (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.
