Ile fire, 13 September 2024 Ile, Alto Molocue

Out · last detection 21 Sept 2024, 11:05 UTC

The fire started on 13 September 2024 in Ile, Mozambique, and satellites saw it burning for 8 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 6,842 hectares from heat detections, spread across 2 municipalities.

It is the 245th largest in Zambézia since 2016 (of 842 with a page). Number 35 in Mozambique in 2024, of 150.

It had gone 8 days without rain (1 mm or more) when it started. Rain came after the fire: 3.0 mm on 22 Sept.

This area had burned before

95% of the perimeter overlaps earlier fires recorded since 2016: 4,230 ha in 2016, 2,429 ha in 2017, 3,596 ha in 2018, 2,511 ha in 2019, 3,452 ha in 2020, 196 ha in 2021, 1,762 ha in 2022, 913 ha in 2023. Part of it burned more than once, so the yearly figures add up to more than the 6,506 ha that had burned before.

Frequently asked questions

How long did the Ile fire last?
GWIS (Copernicus) dates it between 13 September 2024 and 20 September 2024: 8 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 6,842 hectares (68.4 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire entered 2 municipalities: Ile (5,825 ha, 2.0 %); Alto Molocue (1,052 ha, 0.2 %).
What was the weather like?
During the fire the temperature reached 34.0 °C, humidity dropped to 18 % and gusts hit 42 km/h. The fire danger index (FWI) reached 39, 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.

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 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.
