Penguia fire, 31 March 2017 Penguia, Kpeje West, Kpeje Bongre

Out · last detection 9 Apr 2017, 13:32 UTC

The fire started on 31 March 2017 in Penguia, Sierra Leone, and satellites saw it burning for 10 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 4,240 hectares from heat detections, spread across 3 municipalities.

It is the 10th largest in Eastern since 2016 (of 263 with a page). Number 6 in Sierra Leone in 2017, of 207.

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.

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 Penguia fire last?
According to the heat detections seen by satellite inside the perimeter, it burned from 31 March 2017 to 9 April 2017 (10 days). The perimeter dates it from 6 April 2017 to 9 April 2017.
How much area did it burn?
The perimeter GWIS (Copernicus) rebuilt from heat detections is 4,240 hectares (42.4 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire entered 3 municipalities: Penguia (3,480 ha, 16 %); Kpeje West (712 ha, 4.5 %); Kpeje Bongre (75 ha, 0.4 %).
What was the weather like?
During the fire the temperature reached 35.4 °C, humidity dropped to 36 % and gusts hit 35 km/h. The fire danger index (FWI) reached 17, class Moderate.
Where does this data come from?
From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Sierra Leone (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.

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.
  • Dates adjusted with the VIIRS detections inside the perimeter, which said 6 April 2017 to 9 April 2017. 102 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.

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 4.0 (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.
