Rafi fire, January 2023 Rafi, Bosso

Out · last detection 12 Jan 2023, 12:43 UTC

The fire started on 2 January 2023 in Rafi, Nigeria, and satellites saw it burning for 10 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 8,385 hectares from heat detections, spread across 2 municipalities.

It is the 33th largest in Niger since 2016 (of 271 with a page). Number 13 in Nigeria in 2023, of 161.

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

This area had burned before

84% of the perimeter overlaps earlier fires recorded since 2016: 1,571 ha in 2018, 2,135 ha in 2020, 7,166 ha in 2021, 2,540 ha in 2022. Part of it burned more than once, so the yearly figures add up to more than the 7,075 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 Rafi fire last?
GWIS (Copernicus) dates it between 2 January 2023 and 11 January 2023: 10 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 8,385 hectares (83.8 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire entered 2 municipalities: Rafi (8,318 ha, 2.2 %); Bosso (114 ha, 0.1 %).
What was the weather like?
During the fire the temperature reached 35.8 °C, humidity dropped to 16 % and gusts hit 41 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 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.

Emergency number: 112

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 112.

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.
