Ribeirão Cascalheira fire, 13 August 2019 Ribeirão Cascalheira
The fire started on 13 August 2019 in Ribeirão Cascalheira, Brazil, and satellites saw it burning for 19 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 15,863 hectares from heat detections, spread across a single municipality.
It is the 257th largest in Mato Grosso since 2016 (of 1996 with a page). Number 79 in Brazil in 2019, of 974.

Where it burned
How it evolved, day by day
Fire radiative power detected each day, in megawatts, and number of hotspots. The magenta bar marks the peak day.
The weather it burned in
It had gone more than two months without rain (1 mm or more) when it started.
This area had burned before
96% of the perimeter overlaps earlier fires recorded since 2016: 8,504 ha in 2016, 12,512 ha in 2017, 8,738 ha in 2018. Part of it burned more than once, so the yearly figures add up to more than the 15,226 ha that had burned before.

What happened to each town
-
15,985 ha reached on 13 Aug1.4 %
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 2020Inside the perimeter there was no noticeable built-up land and almost nobody lived there (GHSL 2020, 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 Ribeirão Cascalheira fire last?
- According to the heat detections seen by satellite inside the perimeter, it burned from 13 August 2019 to 31 August 2019 (19 days). The perimeter dates it from 14 August 2019 to 25 August 2019.
- How much area did it burn?
- The perimeter GWIS (Copernicus) rebuilt from heat detections is 15,863 hectares (158.6 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire only entered Ribeirão Cascalheira (15,985 ha, 1.4 %).
- What was the weather like?
- During the fire the temperature reached 38.0 °C, humidity dropped to 16 % and gusts hit 47 km/h. The fire danger index (FWI) reached 53, 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; 2 polygons grouped in this page.
- Dates adjusted with the VIIRS detections inside the perimeter, which said 14 August 2019 to 25 August 2019. 582 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 2020, 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.
