Out · last detection 23 Aug 2019, 12:50 UTC

The fire started on 30 July 2019 in Idiofa, Democratic Republic of the Congo, and satellites saw it burning for 25 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 8,110 hectares from heat detections, spread across a single municipality.

It is the 103th largest in Kwilu since 2016 (of 236 with a page). Number 33 in Democratic Republic of the Congo in 2019, of 115.

It had gone one day without rain (1 mm or more) when it started. Rain came after the fire: 2.1 mm on 24 Aug.

This area had burned before

61% of the perimeter overlaps earlier fires recorded since 2016: 94 ha in 2016, 3,344 ha in 2017, 3,023 ha in 2018. Part of it burned more than once, so the yearly figures add up to more than the 4,969 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.

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 Idiofa fire last?
According to the heat detections seen by satellite inside the perimeter, it burned from 30 July 2019 to 23 August 2019 (25 days). The perimeter dates it from 6 August 2019 to 23 August 2019.
How much area did it burn?
The perimeter GWIS (Copernicus) rebuilt from heat detections is 8,110 hectares (81.1 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire only entered Idiofa (8,155 ha, 0.4 %).
What was the weather like?
During the fire the temperature reached 32.2 °C, humidity dropped to 45 % and gusts hit 30 km/h. The fire danger index (FWI) reached 12, class Moderate.
Where does this data come from?
From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Democratic Republic of the Congo (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 August 2019 to 23 August 2019. 320 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 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.
