Katherine fire, 30 September 2024 Katherine
The fire started on 30 September 2024 in Katherine, Australia, and satellites saw it burning for 8 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 12,007 hectares from heat detections, spread across a single municipality.
It is the 1177th largest in Northern Territory since 2016 (of 3503 with a page). Number 206 in Australia in 2024, of 638.

Where it burned
How it evolved, day by day
Fire radiative power detected each day, in megawatts, and number of hotspots. The magenta bar marks the peak day.
The weather it burned in
It had gone 2 days without rain (1 mm or more) when it started. Rain came after the fire: 2.6 mm on 13 Oct.
This area had burned before
70% of the perimeter overlaps earlier fires recorded since 2016: 3,276 ha in 2016, 3,262 ha in 2017, 3,606 ha in 2018, 5,800 ha in 2019, 422 ha in 2020, 637 ha in 2021, 5,330 ha in 2022, 2,256 ha in 2023. Part of it burned more than once, so the yearly figures add up to more than the 8,445 ha that had burned before.

Burnt area inside each municipality, from crossing the GWIS perimeter with administrative boundaries. The distance runs from the point marking the centre of each area to the nearest fire: staying a kilometre away does not mean it reached the houses.
People and buildings inside the perimeter
GHSL 2025Inside the perimeter there were about 10.0 hectares of built-up land and about 100 residents (GHSL 2025, satellite-based estimate).
This is an estimate on 100 m cells, made from satellite imagery and census data: it does not mean that homes burned or that anyone was harmed. The perimeter also contains land that never burned. The GHSL 2025 epoch is a projection made from 2020 and earlier data.

The smoke
CAMS · CopernicusOn 4 October 2024 the air beside the fire reached 136 µg/m³ of PM2.5. That day averaged 50: 3.4 times the WHO daily guideline (15).

Frequently asked questions
- How long did the Katherine fire last?
- GWIS (Copernicus) dates it between 30 September 2024 and 7 October 2024: 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 12,007 hectares (120.1 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire only entered Katherine (12,077 ha, 1.6 %).
- What was the weather like?
- During the fire the temperature reached 39.3 °C, humidity dropped to 12 % and gusts hit 45 km/h. The fire danger index (FWI) reached 54, class Extreme.
- Where does this data come from?
- From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Australia (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 from the perimeter: the VIIRS detections inside it did not change them. 392 Suomi-NPP VIIRS detections on those dates.
- We have not matched this page with any official record.
- Weather: Copernicus ERA5 reanalysis at the fire location, in cells of about 25 km.
- Built-up area and population come from the JRC Global Human Settlement Layer (epoch 2025, 100 m cells), summed inside the perimeter: an estimate of what was there, not a damage count.
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.
