Etheridge fire, 25 October 2025 Etheridge

Out · last detection 2 Nov 2025, 03:51 UTC

The fire started on 25 October 2025 in Etheridge, Australia, and satellites saw it burning for 8 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 9,893 hectares from heat detections, spread across a single municipality.

It is the 771th largest in Queensland since 2016 (of 1737 with a page). Number 502 in Australia in 2025, of 1124.

It had gone 9 days without rain (1 mm or more) when it started. Rain came after the fire: 1.7 mm on 14 Nov.

This area had burned before

64% of the perimeter overlaps earlier fires recorded since 2016: 151 ha in 2016, 1,550 ha in 2017, 4,240 ha in 2019, 1,502 ha in 2021, 56 ha in 2023. Part of it burned more than once, so the yearly figures add up to more than the 6,352 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 4.0 International (CC BY 4.0)). 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.
