Nova Maringá fire, October 2026 Nova Maringá

Burning · last detection 23 Oct 2026, 18:17 UTC

The fire started on 1 October 2026 in Nova Maringá, Brazil, and satellites saw it burning for 22 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 6,297 hectares from heat detections, spread across a single municipality.

It is the 821th largest in Mato Grosso since 2016 (of 1996 with a page). Number 245 in Brazil in 2026, of 747.

Is it still active?

Satellites detected fire on 23 Oct 2026, 18:17 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.

83% of the perimeter overlaps earlier fires recorded since 2016: 2,036 ha in 2017, 316 ha in 2018, 195 ha in 2019, 5,998 ha in 2020, 2,079 ha in 2021, 4,675 ha in 2022, 1,149 ha in 2023. Part of it burned more than once, so the yearly figures add up to more than the 5,250 ha that had burned before.

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.

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.
