Barkly fire, 20 April 2018 Barkly

Out · last detection 27 Apr 2018, 03:34 UTC

The fire started on 20 April 2018 in Barkly, Australia, and satellites saw it burning for 8 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 5,253 hectares from heat detections, spread across a single municipality.

It is the 3272th largest in Northern Territory since 2016 (of 3496 with a page). Number 872 in Australia in 2018, of 923.

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 Barkly fire last?
GWIS (Copernicus) dates it between 20 April 2018 and 27 April 2018: 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 5,253 hectares (52.5 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire only entered Barkly (5,242 ha, 0.0 %).
What was the weather like?
During the fire the temperature reached 36.0 °C, humidity dropped to 8 % and gusts hit 45 km/h. The fire danger index (FWI) reached 69, 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.

Emergency number: 000

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 000.

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.
