How long did the Široki Brijeg fire last?

Copernicus dates it between 14 August 2021 and 15 August 2021: 2 days between the first and last image with fire.

How much area did it burn?

The perimeter Copernicus measured from satellite imagery is 185 hectares (1.8 km²). Official national figures may differ.

Which municipalities burned?

The fire only entered Široki Brijeg (186 ha, 0.5 %).

What was the weather like?

During the fire the temperature reached 34.9 °C, humidity dropped to 20 % and gusts hit 35 km/h. The fire danger index (FWI) reached 32, class High.

Široki Brijeg fire, 14 August 2021 Široki Brijeg

Out · last detection 15 Aug 2021, 12:07 UTC

The fire started on 14 August 2021 in Široki Brijeg, Bosnia & Herzegovina, and satellites saw it burning for 2 days. Copernicus mapped a burnt perimeter of 185 hectares from satellite imagery, spread across a single municipality.

It is the 327th largest in Federation of Bosnia and Herzegovina since 2016 (of 520 with a page). Number 55 in Bosnia & Herzegovina in 2021, of 86.

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 and land cover come from the Copernicus European Forest Fire Information System (EFFIS), measured on MODIS and Sentinel-2 imagery and published under CC BY 4.0. 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 (Public Domain). The area per municipality is computed by WorldFires by crossing the perimeter with those boundaries, so it may differ slightly from each country’s official figure.
