Lizarda fire, August 2025 Lizarda, Rio Sono

Out · last detection 5 Sept 2025, 17:11 UTC

The fire started on 28 August 2025 in Lizarda, Brazil, and satellites saw it burning for 8 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 6,995 hectares from heat detections, spread across 2 municipalities.

It is the 363th largest in Tocantins since 2016 (of 1242 with a page). Number 213 in Brazil in 2025, of 714.

It had gone more than two months without rain (1 mm or more) when it started.

This area had burned before

66% of the perimeter overlaps earlier fires recorded since 2016: 863 ha in 2016, 864 ha in 2017, 872 ha in 2018, 2,563 ha in 2020, 2,677 ha in 2022, 193 ha in 2024. Part of it burned more than once, so the yearly figures add up to more than the 4,586 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 Lizarda fire last?
GWIS (Copernicus) dates it between 28 August 2025 and 4 September 2025: 8 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 6,995 hectares (70.0 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire entered 2 municipalities: Lizarda (5,446 ha, 1.0 %); Rio Sono (1,596 ha, 0.2 %).
What was the weather like?
During the fire the temperature reached 37.8 °C, humidity dropped to 14 % and gusts hit 59 km/h. The fire danger index (FWI) reached 70, class Very extreme.
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.
