Ouadda fire, 20 January 2018 Ouadda

Out · last detection 2 Feb 2018, 11:44 UTC

The fire started on 20 January 2018 in Ouadda, Central African Republic, and satellites saw it burning for 13 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 12,166 hectares from heat detections, spread across a single municipality.

It is the 114th largest in Haute-Kotto since 2016 (of 372 with a page). Number 27 in Central African Republic in 2018, of 81.

48% of the perimeter overlaps earlier fires recorded since 2016: 4,699 ha in 2016, 2,385 ha in 2017. Part of it burned more than once, so the yearly figures add up to more than the 5,788 ha that had burned before.

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 ADM3 (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.
