Grad Gospić fire, February 2017 Grad Gospić
The fire started on 15 February 2017 in Grad Gospić, Croatia, and satellites saw it burning for 7 days. Copernicus mapped a burnt perimeter of 1,137 hectares from satellite imagery, spread across a single municipality.
It is the 5th largest in Lika-Senj since 2016 (of 84 with a page). Number 19 in Croatia in 2017, of 78.
The power measured by the satellite is low (4.6 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 · CopernicusOn 17 February 2017 the air beside the fire reached 38 µg/m³ of PM2.5. That day averaged 26: 1.7 times the WHO daily guideline (15).

Frequently asked questions
- How long did the Grad Gospić fire last?
- According to the heat detections seen by satellite inside the perimeter, it burned from 15 February 2017 to 21 February 2017 (7 days). The perimeter dates it from 16 February 2017 to 21 February 2017.
- How much area did it burn?
- The perimeter Copernicus measured from satellite imagery is 1,137 hectares (11.4 km²). Official national figures may differ.
- Which municipalities burned?
- The fire only entered Grad Gospić (1,137 ha, 1.2 %).
- What was the weather like?
- During the fire the temperature reached 13.7 °C, humidity dropped to 27 % and gusts hit 38 km/h. The fire danger index (FWI) reached 2, 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.

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: EFFIS (Copernicus), mapped on satellite imagery.
- Dates adjusted with the VIIRS detections inside the perimeter, which said 16 February 2017 to 21 February 2017. One Suomi-NPP VIIRS detection 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 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.
