Out · last detection 21 Dec 2016, 12:35 UTC

The fire started on 27 November 2016 in Djema, Central African Republic, and satellites saw it burning for 25 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 10,850 hectares from heat detections, spread across a single municipality.

It is the 116th largest in Haut-Mbomou since 2016 (of 298 with a page). Number 63 in Central African Republic in 2016, of 165.

Frequently asked questions

How long did the Djema fire last?
According to the heat detections seen by satellite inside the perimeter, it burned from 27 November 2016 to 21 December 2016 (25 days). The perimeter dates it from 4 December 2016 to 14 December 2016.
How much area did it burn?
The perimeter GWIS (Copernicus) rebuilt from heat detections is 10,850 hectares (108.5 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire only entered Djema (10,948 ha, 0.3 %).
What was the weather like?
During the fire the temperature reached 35.0 °C, humidity dropped to 11 % and gusts hit 49 km/h. The fire danger index (FWI) reached 56, 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.

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 4 December 2016 to 14 December 2016. 374 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.

How we build fire pages: methodology ›

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.
