Rafaï fire, 10 December 2018 Yalinga, Rafaï

Out · last detection 24 Jan 2019, 23:05 UTC

The fire started on 10 December 2018 in Rafaï, Central African Republic, and satellites saw it burning for 45 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 80,563 hectares from heat detections, spread across 2 municipalities.

This page is probably a fire complex, not a single fire. GWIS merges into one perimeter the fires that touch over weeks, which in large burning seasons can join dozens of separate fires. The total area is reliable; the origin and dates refer to the whole complex.

It is the 4th largest in Mbomou since 2016 (of 80 with a page). Number 7 in Central African Republic in 2018, of 81.

It had gone 36 days without rain (1 mm or more) when it started. Rain came after the fire: 2.1 mm on 28 Jan.

This area had burned before

90% of the perimeter overlaps earlier fires recorded since 2016: 79,263 ha in 2016, 26,011 ha in 2017, 23,449 ha in 2018. Part of it burned more than once, so the yearly figures add up to more than the 72,591 ha that had burned before.

According to the heat detections seen by satellite inside the perimeter, it burned from 10 December 2018 to 23 January 2019 (45 days). The perimeter dates it from 12 December 2018 to 16 January 2019.
How much area did it burn?
The perimeter GWIS (Copernicus) rebuilt from heat detections is 80,563 hectares (805.6 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire entered 2 municipalities: Yalinga (51,311 ha, 1.2 %); Rafaï (29,744 ha, 1.1 %).
What was the weather like?
During the fire the temperature reached 37.9 °C, humidity dropped to 9 % and gusts hit 40 km/h. The fire danger index (FWI) reached 53, class Extreme.
Where does this data come from?
From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Central African Republic (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.

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.
