Out · last detection 19 Sept 2017, 04:59 UTC

The fire started on 3 September 2017 in Guarantã do Norte, Brazil, and satellites saw it burning for 17 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 4,384 hectares from heat detections, spread across a single municipality.

It is the 1278th largest in Mato Grosso since 2016 (of 1996 with a page). Number 567 in Brazil in 2017, of 994.

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 2015
Built-up area1.1 ha
Residents≈ 100

Inside the perimeter there were about 1.1 hectares of built-up land and about 100 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 Guarantã do Norte fire last?
According to the heat detections seen by satellite inside the perimeter, it burned from 3 September 2017 to 19 September 2017 (17 days). The perimeter dates it from 4 September 2017 to 19 September 2017.
How much area did it burn?
The perimeter GWIS (Copernicus) rebuilt from heat detections is 4,384 hectares (43.8 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire only entered Guarantã do Norte (4,414 ha, 0.9 %).
What was the weather like?
During the fire the temperature reached 37.6 °C, humidity dropped to 14 % and gusts hit 42 km/h. The fire danger index (FWI) reached 52, 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.

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.

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 4 September 2017 to 19 September 2017. 131 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.

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.
