Cook fire, 6 June 2023 Cook

Out · last detection 13 Jun 2023, 03:18 UTC

The fire started on 6 June 2023 in Cook, Australia, and satellites saw it burning for 8 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 5,237 hectares from heat detections, spread across a single municipality.

It is the 1630th largest in Queensland since 2016 (of 1737 with a page). Number 1178 in Australia in 2023, of 1235.

The power measured by the satellite is low (14.0 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

It had gone 46 days without rain (1 mm or more) when it started.

This area had burned before

89% of the perimeter overlaps earlier fires recorded since 2016: 3,956 ha in 2016, 870 ha in 2017, 7 ha in 2019, 2,309 ha in 2020, 35 ha in 2022. Part of it burned more than once, so the yearly figures add up to more than the 4,655 ha that had burned before.

How big is it?

It burned the equivalent of 3.3% of the area of London (52 km² against 1,583 km²).

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.

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 Cook fire last?
GWIS (Copernicus) dates it between 6 June 2023 and 13 June 2023: 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 5,237 hectares (52.4 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire only entered Cook (5,293 ha, 0.0 %).
What was the weather like?
During the fire the temperature reached 32.0 °C, humidity dropped to 35 % and gusts hit 53 km/h. The fire danger index (FWI) reached 33, class High.
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. 192 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.

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.
