Out · last detection 22 Sept 2024, 04:58 UTC

The fire started on 20 August 2024 in Juara, Brazil, and satellites saw it burning for 34 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 15,454 hectares from heat detections, spread across 2 municipalities.

It is the 266th largest in Mato Grosso since 2016 (of 1996 with a page). Number 194 in Brazil in 2024, of 1301.

It had gone more than two months without rain (1 mm or more) when it started. Rain came after the fire: 3.6 mm on 27 Sept.

This area had burned before

62% of the perimeter overlaps earlier fires recorded since 2016: 2,686 ha in 2016, 3,731 ha in 2019, 4,886 ha in 2021, 5,127 ha in 2022, 1,032 ha in 2023. Part of it burned more than once, so the yearly figures add up to more than the 9,534 ha that had burned before.

Frequently asked questions

How long did the Juara fire last?
GWIS (Copernicus) dates it between 20 August 2024 and 22 September 2024: 34 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 15,454 hectares (154.5 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire entered 2 municipalities: Juara (15,197 ha, 0.7 %); Nova Bandeirantes (310 ha, 0.0 %).
What was the weather like?
During the fire the temperature reached 37.9 °C, humidity dropped to 12 % and gusts hit 40 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 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.

What do you think is wrong?

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.
