Chereponi fire, 23 December 2017 Chereponi

Out · last detection 24 Dec 2017, 12:36 UTC

The fire started on 23 December 2017 in Chereponi, Ghana, and satellites saw it burning for 2 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 7,474 hectares from heat detections, spread across a single municipality.

It is the 4th largest in North East Region since 2016 (of 68 with a page). Number 8 in Ghana in 2017, of 116.

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.

The weather day by day

ECMWF ERA5 reanalysis at the fire location, the standard reference for past weather, and the Canadian Fire Weather Index (the same system Copernicus uses), computed by WorldFires from that data. Days after the fire run until the first rain.

Frequently asked questions

How long did the Chereponi fire last?
GWIS (Copernicus) dates it between 23 December 2017 and 24 December 2017: 2 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 7,474 hectares (74.7 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire only entered Chereponi (7,481 ha, 5.4 %).
What was the weather like?
During the fire the temperature reached 32.5 °C, humidity dropped to 13 % and gusts hit 34 km/h. The fire danger index (FWI) reached 47, class Very high.
Where does this data come from?
From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Ghana (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.

Emergency number: 112

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 4.0 International (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.
