Moju fire, October 2026 Moju

Burning · last detection 25 Oct 2026, 05:23 UTC

The fire started on 2 October 2026 in Moju, Brazil, and satellites saw it burning for 24 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 3,012 hectares from heat detections, spread across a single municipality.

It is the 1094th largest in Pará since 2016 (of 1098 with a page). Number 750 in Brazil in 2026, of 751.

Is it still active?

Satellites detected fire on 25 Oct 2026, 05:23 UTC. Everything suggests it is still burning. 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.

Frequently asked questions

How long did the Moju fire last?
According to the heat detections seen by satellite inside the perimeter, it burned from 2 October 2026 to 25 October 2026 (24 days). The perimeter dates it from 2 October 2026 to 24 October 2026.
How much area did it burn?
The perimeter GWIS (Copernicus) rebuilt from heat detections is 3,012 hectares (30.1 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire only entered Moju (3,034 ha, 0.3 %).
Is the Moju fire still active?
Yes: satellites detected fire on 25 Oct 2026, 05:23 UTC. Check the emergency service for the official status.
What was the weather like?
During the fire the temperature reached 35.4 °C, humidity dropped to 32 % and gusts hit 38 km/h. The fire danger index (FWI) reached 28, class 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.

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 2 October 2026 to 24 October 2026. 189 Suomi-NPP VIIRS detections on those dates.
  • We have not matched this page with any official record.
  • Weather: ECMWF IFS model, provisional until the ERA5 reanalysis arrives.

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.
