Idiofa fire, 20 July 2016 Idiofa

Out · last detection 6 Aug 2016, 12:00 UTC

The fire started on 20 July 2016 in Idiofa, Congo - Kinshasa, and satellites saw it burning for 17 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 5,309 hectares from heat detections, spread across a single municipality.

It is the 220th largest in Kwilu since 2016 (of 236 with a page). Number 128 in Congo - Kinshasa in 2016, of 153.

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 Idiofa fire last?
GWIS (Copernicus) dates it between 20 July 2016 and 5 August 2016: 17 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 5,309 hectares (53.1 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire only entered Idiofa (5,348 ha, 0.3 %).
What was the weather like?
During the fire the temperature reached 36.2 °C, humidity dropped to 19 % and gusts hit 37 km/h. The fire danger index (FWI) reached 42, class Very high.
Where does this data come from?
From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Congo - Kinshasa (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 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.
