Mufumbwe fire, 9 September 2018 Mufumbwe

Out · last detection 12 Sept 2018, 12:16 UTC

The fire started on 9 September 2018 in Mufumbwe, Zambia, and satellites saw it burning for 4 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 4,879 hectares from heat detections, spread across a single municipality.

It is the 77th largest in North-Western since 2016 (of 286 with a page). Number 81 in Zambia in 2018, of 204.

It had gone more than two months without rain (1 mm or more) when it started.

This area had burned before

53% of the perimeter overlaps earlier fires recorded since 2016: 1,470 ha in 2016, 1,771 ha in 2017. Part of it burned more than once, so the yearly figures add up to more than the 2,583 ha that had burned before.

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.

Frequently asked questions

How long did the Mufumbwe fire last?
GWIS (Copernicus) dates it between 9 September 2018 and 12 September 2018: 4 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 4,879 hectares (48.8 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire only entered Mufumbwe (4,920 ha, 0.3 %).
What was the weather like?
During the fire the temperature reached 31.9 °C, humidity dropped to 12 % and gusts hit 35 km/h. The fire danger index (FWI) reached 46, class Very high.
Where does this data come from?
From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Zambia (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 4.0 (CC BY 4.0)). 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.
