How long did the Boli fire last?

According to the heat detections seen by satellite inside the perimeter, it burned from 10 January 2018 to 16 January 2018 (7 days). The perimeter dates it from 11 January 2018 to 13 January 2018.

How much area did it burn?

The perimeter GWIS (Copernicus) rebuilt from heat detections is 1,038 hectares (10.4 km²). It is an estimate: official national figures may differ.

Which municipalities burned?

The fire only entered Boli (1,045 ha, 3.4 %).

Where does this data come from?

From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Côte d’Ivoire (geoBoundaries). It is not an official report.

The fire started on 10 January 2018 in Boli, Côte d’Ivoire, and satellites saw it burning for 7 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 1,038 hectares from heat detections, spread across a single municipality.

It is the 123th largest in Lacs since 2016 (of 139 with a page). Number 93 in Côte d’Ivoire in 2018, of 98.

The power measured by the satellite is low (26.3 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

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.
