Itaituba fire, July 2022 Itaituba
Out · last detection 1 Sept 2022, 04:58 UTC
The fire started on 29 July 2022 in Itaituba, Brazil, and satellites saw it burning for 35 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 3,696 hectares from heat detections, spread across a single municipality.
It is the 684th largest in Pará since 2016 (of 957 with a page). Number 464 in Brazil in 2022, of 682.

Satellites pass a few times a day and cloud or smoke can hide the fire: a lack of detections is not an official extinction. Each country’s emergency service declares a fire contained or out.

52% of the perimeter overlaps earlier fires recorded since 2016: 248 ha in 2016, 911 ha in 2018, 1,125 ha in 2019, 975 ha in 2020, 900 ha in 2021. Part of it burned more than once, so the yearly figures add up to more than the 1,907 ha that had burned before.

In 10 of 15, not even 1 mm fell in the ten days after the end: they went out without rain. In the rest, the first rainy day brought a median of 1.6 mm.

How a twin is chosen
- Same area: fires that have already ended, less than 250 km from this one, since 2016.
- Same start: we compare the FWI on the first day, the minimum humidity that day and the run of days without rain before it. The slider sets how much they may differ.
- Only pages with final weather data (ERA5 reanalysis) calculated in the same way as this fire’s; agricultural and grass burns and pages with data under review are left out.
- Fires burning at the same time as this one (a week before or after) are left out: they share the same spell of weather and do not count as a precedent.
- They are sorted by similarity, and the outlines of the first five are drawn.

- According to the heat detections seen by satellite inside the perimeter, it burned from 29 July 2022 to 1 September 2022 (35 days). The perimeter dates it from 1 August 2022 to 25 August 2022.
- How much area did it burn?
- The perimeter GWIS (Copernicus) rebuilt from heat detections is 3,696 hectares (37.0 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire only entered Itaituba (3,727 ha, 0.1 %).
- What was the weather like?
- During the fire the temperature reached 37.0 °C, humidity dropped to 23 % and gusts hit 37 km/h. The fire danger index (FWI) reached 42, 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.
- How did the fires that started in similar weather in this area end?
- Fires less than 250 km away that started since 2016 with a similar FWI, humidity and dry spell: 15. Their median duration was 16 days and their median area 4,057 ha; 20 % went past 10,000 ha. In 10 of 15, not even 1 mm fell in the ten days after the end: they went out without rain. In the rest, the first rainy day brought a median of 1.6 mm.
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.
- Dates adjusted with the VIIRS detections inside the perimeter, which said 1 August 2022 to 25 August 2022. 348 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.
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.
