Lábrea fire, 11 July 2024 Lábrea

Out · last detection 23 Jul 2024, 18:19 UTC

The fire started on 11 July 2024 in Lábrea, Brazil, and satellites saw it burning for 16 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 5,855 hectares from heat detections, spread across a single municipality.

It is the 123th largest in Amazonas since 2016 (of 450 with a page). Number 575 in Brazil in 2024, of 1301.

It had gone 30 days without rain (1 mm or more) when it started. Rain came after the fire: 1.3 mm on 4 Aug.

This area had burned before

88% of the perimeter overlaps earlier fires recorded since 2016: 999 ha in 2016, 1,148 ha in 2017, 3,140 ha in 2018, 2,498 ha in 2019, 2,266 ha in 2020, 1,498 ha in 2021, 5,272 ha in 2022, 1,129 ha in 2023. Part of it burned more than once, so the yearly figures add up to more than the 5,154 ha that had burned before.

Frequently asked questions

How long did the Lábrea fire last?
GWIS (Copernicus) dates it between 11 July 2024 and 26 July 2024: 16 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 5,855 hectares (58.6 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire only entered Lábrea (5,904 ha, 0.1 %).
What was the weather like?
During the fire the temperature reached 36.7 °C, humidity dropped to 23 % and gusts hit 36 km/h. The fire danger index (FWI) reached 36, class High.
Where does this data come from?
From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Brazil (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.

Emergency number: 193

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.

We will only use your email to reply about this report. Privacy. This is not an emergency service: if there is a fire now, call 193.

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.
