Kazumba fire, 20 July 2020 Kazumba

Out · last detection 19 Aug 2020, 11:21 UTC

The fire started on 20 July 2020 in Kazumba, Democratic Republic of the Congo, and satellites saw it burning for 30 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 12,881 hectares from heat detections, spread across a single municipality.

It is the 9th largest in Central Kasai since 2016 (of 64 with a page). Number 28 in Democratic Republic of the Congo in 2020, of 165.

It had gone more than two months without rain (1 mm or more) when it started. Rain came after the fire: 9.4 mm on 19 Aug.

This area had burned before

60% of the perimeter overlaps earlier fires recorded since 2016: 1,493 ha in 2016, 5,164 ha in 2017, 1,114 ha in 2018, 3,352 ha in 2019. Part of it burned more than once, so the yearly figures add up to more than the 7,782 ha that had burned before.

Built-up area1.3 ha
Residents≈ 450

Inside the perimeter there were about 1.3 hectares of built-up land and about 450 residents (GHSL 2020, satellite-based estimate).

This is an estimate on 100 m cells, made from satellite imagery and census data: it does not mean that homes burned or that anyone was harmed. The perimeter also contains land that never burned.

Its twins: fires that started in the same weather

It was 2.1 times larger than the median of its twins and lasted 30 days, against 16 days.

Only 2 of its 15 twins burned more. The weather on the first day does not explain everything: the wind in the following days, the fuel and the firefighting also count. In 10 of 15, not even 1 mm fell in the ten days after the end: they went out without rain. In the rest, the first rainy day brought a median of 1.7 mm.

It was considered over on 18 Aug, and on 19 Aug 9.4 mm fell. We do not know whether the rain or the firefighters put it out. Twins with rain when they ended: 5 of 15, with a median of 1.7 mm.

How a twin is chosen

  • Same area: fires that have already ended, less than 250 km from this one, since 2016.
  • Same start: we compare the FWI on the first day, the minimum humidity that day and the run of days without rain before it. The slider sets how much they may differ.
  • Only pages with final weather data (ERA5 reanalysis) calculated in the same way as this fire’s; agricultural and grass burns and pages with data under review are left out.
  • Fires burning at the same time as this one (a week before or after) are left out: they share the same spell of weather and do not count as a precedent.
  • They are sorted by similarity, and the outlines of the first five are drawn.

Frequently asked questions

How long did the Kazumba fire last?
According to the heat detections seen by satellite inside the perimeter, it burned from 20 July 2020 to 18 August 2020 (30 days). The perimeter dates it from 27 July 2020 to 11 August 2020.
How much area did it burn?
The perimeter GWIS (Copernicus) rebuilt from heat detections is 12,881 hectares (128.8 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire only entered Kazumba (12,958 ha, 1.0 %).
What was the weather like?
During the fire the temperature reached 33.4 °C, humidity dropped to 20 % and gusts hit 34 km/h. The fire danger index (FWI) reached 37, class High.
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.
How did the fires that started in similar weather in this area end?
Fires less than 250 km away that started since 2016 with a similar FWI, humidity and dry spell: 15. Their median duration was 16 days and their median area 6,087 ha; 13 % went past 10,000 ha. Only 2 of its 15 twins burned more. The weather on the first day does not explain everything: the wind in the following days, the fuel and the firefighting also count. In 10 of 15, not even 1 mm fell in the ten days after the end: they went out without rain. In the rest, the first rainy day brought a median of 1.7 mm.

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 27 July 2020 to 11 August 2020. 971 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.
  • Built-up area and population come from the JRC Global Human Settlement Layer (epoch 2020, 100 m cells), summed inside the perimeter: an estimate of what was there, not a damage count.

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 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.
