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.

Frequently asked questions

How long did the Dueré fire last?
According to the heat detections seen by satellite inside the perimeter, it burned from 26 August 2016 to 20 September 2016 (26 days). The perimeter dates it from 2 September 2016 to 16 September 2016.
How much area did it burn?
The perimeter GWIS (Copernicus) rebuilt from heat detections is 21,092 hectares (210.9 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire entered 3 municipalities: Dueré (13,336 ha, 3.9 %); Santa Rita do Tocantins (4,637 ha, 1.4 %); Lagoa da Confusão (3,240 ha, 0.3 %).
What was the weather like?
During the fire the temperature reached 39.8 °C, humidity dropped to 13 % and gusts hit 47 km/h. The fire danger index (FWI) reached 61, 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.

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 adjusted with the VIIRS detections inside the perimeter, which said 2 September 2016 to 16 September 2016. 1,342 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.

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.
