Maban fire, December 2017 Maban

Out · last detection 18 Dec 2017, 11:07 UTC

The fire started on 15 December 2017 in Maban, South Sudan, and satellites saw it burning for 4 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 5,386 hectares from heat detections, spread across a single municipality.

It is the 251th largest in Upper Nile since 2016 (of 284 with a page). Number 180 in South Sudan in 2017, of 203.

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 Maban fire last?
GWIS (Copernicus) dates it between 15 December 2017 and 18 December 2017: 4 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 5,386 hectares (53.9 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire only entered Maban (5,416 ha, 0.5 %).
What was the weather like?
During the fire the temperature reached 39.1 °C, humidity dropped to 14 % and gusts hit 40 km/h. The fire danger index (FWI) reached 52, class Extreme.
Where does this data come from?
From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of South Sudan (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.

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.

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.
