Mecula fire, 19 October 2018 Mecula, Mavago

Out · last detection 31 Oct 2018, 11:57 UTC

The fire started on 19 October 2018 in Mecula, Mozambique, and satellites saw it burning for 13 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 5,990 hectares from heat detections, spread across 2 municipalities.

It is the 160th largest in Niassa since 2016 (of 577 with a page). Number 53 in Mozambique in 2018, of 220.

It had gone 16 days without rain (1 mm or more) when it started. Rain came after the fire: 1.8 mm on 4 Nov.

This area had burned before

43% of the perimeter overlaps earlier fires recorded since 2016: 1,831 ha in 2016, 1,471 ha in 2017. Part of it burned more than once, so the yearly figures add up to more than the 2,594 ha that had burned before.

How big is it?

10 km
It burned the equivalent of 3.8% of the area of London (60 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 area< 0.1 ha
Residents< 20

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.

Frequently asked questions

How long did the Mecula fire last?
GWIS (Copernicus) dates it between 19 October 2018 and 31 October 2018: 13 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 5,990 hectares (59.9 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire entered 2 municipalities: Mecula (5,799 ha, 0.3 %); Mavago (233 ha, 0.0 %).
What was the weather like?
During the fire the temperature reached 31.8 °C, humidity dropped to 31 % and gusts hit 53 km/h. The fire danger index (FWI) reached 29, class 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. 247 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.
