Grad Gospić fire, 20 March 2017 Grad Gospić

Out · last detection 21 Mar 2017, 12:57 UTC

The fire started on 20 March 2017 in Grad Gospić, Croatia, and satellites saw it burning for 2 days. Copernicus mapped a burnt perimeter of 223 hectares from satellite imagery, spread across a single municipality.

It is the 36th largest in Lika-Senj since 2016 (of 84 with a page). Number 55 in Croatia in 2017, of 78.

The power measured by the satellite is low (12.3 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

The smoke

CAMS · Copernicus

On 18 March 2017 the air beside the fire reached 35 µg/m³ of PM2.5. That day averaged 22: 1.5 times the WHO daily guideline (15).

Frequently asked questions

How long did the Grad Gospić fire last?
Copernicus dates it between 20 March 2017 and 21 March 2017: 2 days between the first and last image with fire.
How much area did it burn?
The perimeter Copernicus measured from satellite imagery is 223 hectares (2.2 km²). Official national figures may differ.
Which municipalities burned?
The fire only entered Grad Gospić (223 ha, 0.2 %).
What was the weather like?
During the fire the temperature reached 18.1 °C, humidity dropped to 50 % and gusts hit 28 km/h. The fire danger index (FWI) reached 3, class Very low.
Where does this data come from?
From the EFFIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Croatia (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.

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 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 (Creative Commons Attribution-ShareAlike 2.0). 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.
