Cáceres fire, 12 November 2023 Cáceres

Out · last detection 18 Nov 2023, 04:55 UTC

The fire started on 12 November 2023 in Cáceres, Brazil, and satellites saw it burning for 7 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 8,248 hectares from heat detections, spread across a single municipality.

It is the 588th largest in Mato Grosso since 2016 (of 1996 with a page). Number 70 in Brazil in 2023, of 431.

It had gone 8 days without rain (1 mm or more) when it started. Rain came after the fire: 23.0 mm on 19 Nov.

This area had burned before

85% of the perimeter overlaps earlier fires recorded since 2016: 4 ha in 2019, 7,092 ha in 2020, 2,025 ha in 2021. Part of it burned more than once, so the yearly figures add up to more than the 7,005 ha that had burned before.

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.

ECMWF ERA5 reanalysis at the fire location, the standard reference for past weather, and the Canadian Fire Weather Index (the same system Copernicus uses), computed by WorldFires from that data. Days after the fire run until the first rain.

Frequently asked questions

How long did the Cáceres fire last?
GWIS (Copernicus) dates it between 12 November 2023 and 18 November 2023: 7 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 8,248 hectares (82.5 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire only entered Cáceres (8,303 ha, 0.3 %).
What was the weather like?
During the fire the temperature reached 41.8 °C, humidity dropped to 26 % and gusts hit 54 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.

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.
