Out · last detection 5 Sept 2019, 12:04 UTC

The fire started on 19 August 2019 in Milengi, Zambia, and satellites saw it burning for 18 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 3,010 hectares from heat detections, spread across 2 municipalities.

It is the 444th largest in Luapula since 2016 (of 449 with a page). Number 243 in Zambia in 2019, of 243.

It had gone more than two months without rain (1 mm or more) when it started.

This area had burned before

94% of the perimeter overlaps earlier fires recorded since 2016: 1,624 ha in 2016, 1,565 ha in 2017, 1,778 ha in 2018. Part of it burned more than once, so the yearly figures add up to more than the 2,821 ha that had burned before.

How big is it?

It burned the equivalent of 1.9% of the area of London (30 km² against 1,583 km²).

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 Milengi fire last?
According to the heat detections seen by satellite inside the perimeter, it burned from 19 August 2019 to 5 September 2019 (18 days). The perimeter dates it from 21 August 2019 to 29 August 2019.
How much area did it burn?
The perimeter GWIS (Copernicus) rebuilt from heat detections is 3,010 hectares (30.1 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire entered 2 municipalities: Mansa (2,913 ha, 0.4 %); Milengi (120 ha, 0.0 %).
What was the weather like?
During the fire the temperature reached 32.9 °C, humidity dropped to 17 % and gusts hit 49 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 Zambia (geoBoundaries). It is not an official report.
How did the fires that started in similar weather in this area end?
Fires less than 250 km away that started since 2016 with a similar FWI, humidity and dry spell: 46. Their median duration was 17 days and their median area 5,181 ha; 28 % went past 10,000 ha. In 45 of 46, not even 1 mm fell in the ten days after the end: they went out without rain. In the rest, the first rainy day brought a median of 3.3 mm.

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 adjusted with the VIIRS detections inside the perimeter, which said 21 August 2019 to 29 August 2019. 106 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 (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.
