Barh-Signaka fire, 6 November 2016 Barh-Signaka

Out · last detection 12 Nov 2016, 11:27 UTC

The fire started on 6 November 2016 in Barh-Signaka, Chad, and satellites saw it burning for 7 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 6,814 hectares from heat detections, spread across a single municipality.

It is the 20th largest in Guéra since 2016 (of 193 with a page). Number 13 in Chad in 2016, of 220.

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

Built-up area< 0.1 ha
Residents< 20

Inside the perimeter there was no noticeable built-up land and almost nobody lived there (GHSL 2015, 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.

Its twins: fires that started in the same weather

It started with an FWI of 37.7, a minimum humidity of 18% and 28 days without rain. Fires in the area that started in weather like this since 2016: 31.

It was 2.5 times larger than the median of its twins and lasted 7 days, against 5 days.

Only 1 of its 31 twins burned more. The weather on the first day does not explain everything: the wind in the following days, the fuel and the firefighting also count. In none of them did 1 mm fall in the ten days after the end: they all went out without rain.

It was considered over on 12 Nov, and not even 1 mm fell in the following ten days: it went out without rain. None of its 31 twins had rain when they ended.

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 Barh-Signaka fire last?
GWIS (Copernicus) dates it between 6 November 2016 and 12 November 2016: 7 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 6,814 hectares (68.1 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire only entered Barh-Signaka (6,866 ha, 0.2 %).
What was the weather like?
During the fire the temperature reached 38.2 °C, humidity dropped to 13 % and gusts hit 38 km/h. The fire danger index (FWI) reached 49, class Very high.
Where does this data come from?
From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Chad (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: 31. Their median duration was 5 days and their median area 2,721 ha; 100 % went past 1,000 ha. Only 1 of its 31 twins burned more. The weather on the first day does not explain everything: the wind in the following days, the fuel and the firefighting also count. In none of them did 1 mm fall in the ten days after the end: they all went out without rain.

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; 2 polygons grouped in this page.
  • Dates from the perimeter: the VIIRS detections inside it did not change them. 189 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 2015, 100 m cells), summed inside the perimeter: an estimate of what was there, not a damage count.

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 3.0 Intergovernmental Organisations (CC BY 3.0 IGO)). 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.
