Cumaru do Norte fire, 10 August 2017 Cumaru do Norte, São Félix do Xingu, Santana do Araguaia
The fire started on 10 August 2017 in Cumaru do Norte, Brazil, and satellites saw it burning for 58 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 215,807 hectares from heat detections, spread across 3 municipalities.
This page is probably a fire complex, not a single fire. GWIS merges into one perimeter the fires that touch over weeks, which in large burning seasons can join dozens of separate fires. The total area is reliable; the origin and dates refer to the whole complex.

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.
People and buildings inside the perimeter
GHSL 2015Inside the perimeter there were about 5.6 hectares of built-up land and about 300 residents (GHSL 2015, satellite-based estimate).
This is an estimate on 100 m cells, made from satellite imagery and census data: it does not mean that homes burned or that anyone was harmed. The perimeter also contains land that never burned.

Frequently asked questions
- How long did the Cumaru do Norte fire last?
- According to the heat detections seen by satellite inside the perimeter, it burned from 10 August 2017 to 6 October 2017 (58 days). The perimeter dates it from 17 August 2017 to 30 September 2017.
- How much area did it burn?
- The perimeter GWIS (Copernicus) rebuilt from heat detections is 215,807 hectares (2,158.1 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire entered 3 municipalities: Cumaru do Norte (150,501 ha, 8.8 %); São Félix do Xingu (66,837 ha, 0.8 %); Santana do Araguaia (336 ha, 0.0 %).
- What was the weather like?
- During the fire the temperature reached 37.4 °C, humidity dropped to 20 % and gusts hit 46 km/h. The fire danger index (FWI) reached 49, class Very 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.

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; 3 polygons grouped in this page.
- Dates adjusted with the VIIRS detections inside the perimeter, which said 17 August 2017 to 30 September 2017. 9,986 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.
- Built-up area and population come from the JRC Global Human Settlement Layer (epoch 2015, 100 m cells), summed inside the perimeter: an estimate of what was there, not a damage count.
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.
