Uruará fire, 16 November 2024 Uruará

Out · last detection 4 Dec 2024, 05:28 UTC

The fire started on 16 November 2024 in Uruará, Brazil, and satellites saw it burning for 19 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 3,672 hectares from heat detections, spread across a single municipality.

It is the 797th largest in Pará since 2016 (of 1095 with a page). Number 1008 in Brazil in 2024, of 1301.

It had gone 5 days without rain (1 mm or more) when it started. Rain came after the fire: 5.4 mm on 12 Dec.

This area had burned before

5% of the perimeter overlaps earlier fires recorded since 2016: 150 ha in 2022, 124 ha in 2023. Part of it burned more than once, so the yearly figures add up to more than the 172 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.

The weather day by day

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 Uruará fire last?
GWIS (Copernicus) dates it between 16 November 2024 and 4 December 2024: 19 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 3,672 hectares (36.7 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire only entered Uruará (3,696 ha, 0.3 %).
What was the weather like?
During the fire the temperature reached 35.1 °C, humidity dropped to 39 % and gusts hit 38 km/h. The fire danger index (FWI) reached 20, class Moderate.
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.
