Lizarda fire, 23 October 2025 Lizarda, Rio Sono, São Félix do Tocantins

Out · last detection 30 Oct 2025, 16:41 UTC

The fire started on 23 October 2025 in Lizarda, Brazil, and satellites saw it burning for 7 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 14,656 hectares from heat detections, spread across 4 municipalities.

It is the 111th largest in Tocantins since 2016 (of 1242 with a page). Number 64 in Brazil in 2025, of 714.

It had gone one day without rain (1 mm or more) when it started. Rain came after the fire: 4.4 mm on 1 Nov.

This area had burned before

72% of the perimeter overlaps earlier fires recorded since 2016: 4,776 ha in 2016, 702 ha in 2020, 9,192 ha in 2022. Part of it burned more than once, so the yearly figures add up to more than the 10,501 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.

Frequently asked questions

How long did the Lizarda fire last?
GWIS (Copernicus) dates it between 23 October 2025 and 29 October 2025: 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 14,656 hectares (146.6 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire entered 4 municipalities: Lizarda (14,226 ha, 2.5 %); Rio Sono (279 ha, 0.0 %); São Félix do Tocantins (190 ha, 0.1 %); Novo Acordo (75 ha, 0.0 %).
What was the weather like?
During the fire the temperature reached 40.5 °C, humidity dropped to 15 % and gusts hit 55 km/h. The fire danger index (FWI) reached 58, class 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.
