Aripuanã fire, July 2024 Aripuanã

Out · last detection 16 Aug 2024, 04:53 UTC

The fire started on 27 July 2024 in Aripuanã, Brazil, and satellites saw it burning for 20 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 4,430 hectares from heat detections, spread across a single municipality.

It is the 1255th largest in Mato Grosso since 2016 (of 1996 with a page). Number 799 in Brazil in 2024, of 1301.

Burnt area inside each municipality, from crossing the GWIS perimeter with administrative boundaries. The distance is from the town centre to the nearest fire: staying a kilometre away does not mean it reached the houses.

Frequently asked questions

How long did the Aripuanã fire last?
GWIS (Copernicus) dates it between 27 July 2024 and 15 August 2024: 20 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 4,430 hectares (44.3 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire only entered Aripuanã (4,461 ha, 0.2 %).
What was the weather like?
During the fire the temperature reached 36.1 °C, humidity dropped to 19 % and gusts hit 39 km/h. The fire danger index (FWI) reached 46, 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.

What do you think is wrong?

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.
