Mid-Coast fire, October 2019 Mid-Coast, Walcha, Port Macquarie-Hastings

Out · last detection 10 Jan 2020, 15:07 UTC

The fire started on 17 October 2019 in Mid-Coast, Australia, and satellites saw it burning for 86 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 204,662 hectares from heat detections, spread across 3 municipalities.

This page is probably a fire complex, not a single fire. GWIS merges into one perimeter the fires that touch over weeks, which in large burning seasons can join dozens of separate fires. The total area is reliable; the origin and dates refer to the whole complex.

Other fire pages in the same area and on the same dates:

It is the 5th largest in New South Wales since 2016 (of 121 with a page). Number 7 in Australia in 2019, of 288.

It had gone 4 days without rain (1 mm or more) when it started. Rain came after the fire: 1.3 mm on 11 Jan.

This area had burned before

14% of the perimeter overlaps earlier fires recorded since 2016: 17,370 ha in 2016, 9,881 ha in 2017, 3,187 ha in 2018. Part of it burned more than once, so the yearly figures add up to more than the 28,988 ha that had burned before.

How a twin is chosen

  • Same area: fires that have already ended, less than 250 km from this one, since 2016.
  • Same start: we compare the FWI on the first day, the minimum humidity that day and the run of days without rain before it. The slider sets how much they may differ.
  • Only pages with final weather data (ERA5 reanalysis) calculated in the same way as this fire’s; agricultural and grass burns and pages with data under review are left out.
  • Fires burning at the same time as this one (a week before or after) are left out: they share the same spell of weather and do not count as a precedent.
  • They are sorted by similarity, and the outlines of the first five are drawn.

Frequently asked questions

How long did the Mid-Coast fire last?
According to the heat detections seen by satellite inside the perimeter, it burned from 17 October 2019 to 10 January 2020 (86 days). The perimeter dates it from 18 October 2019 to 10 January 2020.
How much area did it burn?
The perimeter GWIS (Copernicus) rebuilt from heat detections is 204,662 hectares (2,046.6 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire entered 3 municipalities: Mid-Coast (154,496 ha, 15 %); Walcha (49,448 ha, 7.9 %); Port Macquarie-Hastings (3,778 ha, 1.0 %).
What was the weather like?
During the fire the temperature reached 41.0 °C, humidity dropped to 10 % and gusts hit 88 km/h. The fire danger index (FWI) reached 62, 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; 4 polygons grouped in this page.
  • Dates adjusted with the VIIRS detections inside the perimeter, which said 18 October 2019 to 10 January 2020. 34,124 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.

How we build fire pages: methodology

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.
