How long did the Eruh fire last?

Copernicus dates it between 14 August 2021 and 16 August 2021: 3 days between the first and last image with fire.

How much area did it burn?

The perimeter Copernicus measured from satellite imagery is 396 hectares (4.0 km²). Official national figures may differ.

Which municipalities burned?

The fire only entered Eruh (396 ha, 0.4 %).

Did the fire reach a town?

The closest fire to a town centre came within 13.0 km of Eruh. That is the distance to the perimeter or nearest hotspot; it does not mean it entered the houses.

What was the weather like?

During the fire the temperature reached 31.4 °C, humidity dropped to 12 % and gusts hit 52 km/h. The fire danger index (FWI) reached 52, class Extreme.

Where does this data come from?

From the EFFIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Türkiye (geoBoundaries). It is not an official report.

Eruh fire, August 2021 Eruh

Out · last detection 14 Aug 2021, 23:03 UTC

The fire started on 14 August 2021 in Eruh, Türkiye, and satellites saw it burning for 3 days. Copernicus mapped a burnt perimeter of 396 hectares from satellite imagery, spread across a single municipality.

It is the 11th largest in Siirt since 2016 (of 43 with a page). Number 51 in Türkiye in 2021, of 138.

The power measured by the satellite is low (19.0 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 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 ADM2 (Open Data Commons Open Database License 1.0). 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.
