Out · last detection 18 Sept 2022, 04:41 UTC

The fire started on 27 August 2022 in Dueré, Brazil, and satellites saw it burning for 23 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 8,352 hectares from heat detections, spread across 3 municipalities.

It is the 277th largest in Tocantins since 2016 (of 1242 with a page). Number 153 in Brazil in 2022, of 687.

It had gone more than two months without rain (1 mm or more) when it started. Rain came after the fire: 1.0 mm on 21 Sept.

This area had burned before

99% of the perimeter overlaps earlier fires recorded since 2016: 6,520 ha in 2016, 5,077 ha in 2017, 6,886 ha in 2019, 3,688 ha in 2020, 256 ha in 2021. Part of it burned more than once, so the yearly figures add up to more than the 8,269 ha that had burned before.

Burnt area inside each municipality, from crossing the GWIS perimeter with administrative boundaries. The distance is from the town centre to the nearest fire: staying a kilometre away does not mean it reached the houses.

Frequently asked questions

How long did the Dueré fire last?
GWIS (Copernicus) dates it between 27 August 2022 and 18 September 2022: 23 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 8,352 hectares (83.5 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire entered 3 municipalities: Dueré (7,262 ha, 2.1 %); Lagoa da Confusão (692 ha, 0.1 %); Santa Rita do Tocantins (445 ha, 0.1 %).
What was the weather like?
During the fire the temperature reached 39.7 °C, humidity dropped to 14 % and gusts hit 54 km/h. The fire danger index (FWI) reached 64, 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.

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.
