Milange fire, 11 September 2020 Milange

Out · last detection 22 Sept 2020, 10:40 UTC

The fire started on 11 September 2020 in Milange, Mozambique, and satellites saw it burning for 11 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 13,746 hectares from heat detections, spread across a single municipality.

It is the 113th largest in Zambézia since 2016 (of 842 with a page). Number 17 in Mozambique in 2020, of 193.

It had gone 3 days without rain (1 mm or more) when it started.

This area had burned before

76% of the perimeter overlaps earlier fires recorded since 2016: 7,682 ha in 2016, 2,200 ha in 2017, 4,294 ha in 2018, 2,975 ha in 2019. Part of it burned more than once, so the yearly figures add up to more than the 10,398 ha that had burned before.

How big is it?

10 km
It burned the equivalent of 8.7% of the area of London (137 km² against 1,583 km²).

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.

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 Milange fire last?
GWIS (Copernicus) dates it between 11 September 2020 and 21 September 2020: 11 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 13,746 hectares (137.5 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire only entered Milange (13,837 ha, 2.5 %).
What was the weather like?
During the fire the temperature reached 36.7 °C, humidity dropped to 18 % and gusts hit 49 km/h. The fire danger index (FWI) reached 44, class Very high.
Where does this data come from?
From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Mozambique (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 from the perimeter: the VIIRS detections inside it did not change them. 655 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.

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.
