Corumbá fire, 1 July 2021 Corumbá

Out · last detection 16 Jul 2021, 17:57 UTC

The fire started on 1 July 2021 in Corumbá, Brazil, and satellites saw it burning for 15 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 19,714 hectares from heat detections, spread across a single municipality.

It is the 60th largest in Mato Grosso do Sul since 2016 (of 506 with a page). Number 59 in Brazil in 2021, of 814.

Frequently asked questions

How long did the Corumbá fire last?
GWIS (Copernicus) dates it between 1 July 2021 and 15 July 2021: 15 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 19,714 hectares (197.1 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire only entered Corumbá (19,794 ha, 0.3 %).
What was the weather like?
During the fire the temperature reached 35.4 °C, humidity dropped to 18 % and gusts hit 41 km/h. The fire danger index (FWI) reached 47, 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.

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.
