Hurungwe fire, 18 September 2022 Hurungwe
Out · last detection 11 Oct 2022, 11:38 UTC
The fire started on 18 September 2022 in Hurungwe, Zimbabwe, and satellites saw it burning for 24 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 7,898 hectares from heat detections, spread across a single municipality.
It is the 20th largest in Mashonaland West since 2016 (of 642 with a page). Number 14 in Zimbabwe in 2022, of 346.

Satellites pass a few times a day and cloud or smoke can hide the fire: a lack of detections is not an official extinction. Each country’s emergency service declares a fire contained or out.

Inside the perimeter there was no noticeable built-up land and almost nobody lived there (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.

It was 4.9 times larger than the median of its twins and lasted 24 days, against 4 days.
Only 1 of its 34 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 19 of 34, 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 2.9 mm.
This is a bank of analogues: it shows what usually happens, not what will happen. With fewer than 15 twins we give no figures. How we calculate it

It was considered over on 11 Oct, and not even 1 mm fell in the following ten days: it went out without rain. Twins with rain when they ended: 15 of 34, with a median of 2.9 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 Hurungwe fire last?
- According to the heat detections seen by satellite inside the perimeter, it burned from 18 September 2022 to 11 October 2022 (24 days). The perimeter dates it from 23 September 2022 to 11 October 2022.
- How much area did it burn?
- The perimeter GWIS (Copernicus) rebuilt from heat detections is 7,898 hectares (79.0 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire only entered Hurungwe (7,932 ha, 0.4 %).
- What was the weather like?
- During the fire the temperature reached 36.2 °C, humidity dropped to 11 % and gusts hit 57 km/h. The fire danger index (FWI) reached 96, class Very extreme.
- Where does this data come from?
- From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Zimbabwe (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: 34. Their median duration was 4 days and their median area 1,598 ha; 100 % went past 1,000 ha. Only 1 of its 34 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 19 of 34, 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 2.9 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 23 September 2022 to 11 October 2022. 260 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.
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.
