Out · last detection 5 Oct 2020, 22:46 UTC

The fire started on 13 September 2020 in Mocuba, Mozambique, and satellites saw it burning for 22 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 86,463 hectares from heat detections, spread across 3 municipalities.

It is the 16th largest in Zambézia since 2016 (of 842 with a page). Number 2 in Mozambique in 2020, of 193.

It had gone 7 days without rain (1 mm or more) when it started. Rain came after the fire: 5.6 mm on 11 Oct.

This area had burned before

86% of the perimeter overlaps earlier fires recorded since 2016: 44,314 ha in 2016, 26,657 ha in 2017, 52,007 ha in 2018, 40,129 ha in 2019. Part of it burned more than once, so the yearly figures add up to more than the 74,165 ha that had burned before.

How big is it?

It burned the equivalent of 55% of the area of London (865 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.

People and buildings inside the perimeter

GHSL 2020
Built-up area62 ha
Residents≈ 15,000

Inside the perimeter there were about 62 hectares of built-up land and about 15,000 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.

Frequently asked questions

How long did the Mocuba fire last?
GWIS (Copernicus) dates it between 13 September 2020 and 4 October 2020: 22 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 86,463 hectares (864.6 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire entered 3 municipalities: Mocuba (76,853 ha, 8.7 %); Derre (9,736 ha, 2.0 %); Lugela (293 ha, 0.0 %).
What was the weather like?
During the fire the temperature reached 38.7 °C, humidity dropped to 16 % and gusts hit 50 km/h. The fire danger index (FWI) reached 51, class Extreme.
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; 9 polygons grouped in this page.
  • Dates from the perimeter: the VIIRS detections inside it did not change them. 6,395 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.
