Grad Vrlika fire, April 2016 Grad Vrlika, Općina Civljane
The fire started on 5 April 2016 in Grad Vrlika, Croatia, and satellites saw it burning for 3 days. Copernicus mapped a burnt perimeter of 2,836 hectares from satellite imagery, spread across 2 municipalities.
It is the 7th largest in Split-Dalmatia since 2016 (of 48 with a page). The largest in Croatia in 2016, of 20.

The smoke
CAMS · CopernicusOn 3 April 2016 the air beside the fire reached 34 µg/m³ of PM2.5. That day averaged 24: 1.6 times the WHO daily guideline (15).

Frequently asked questions
- How long did the Grad Vrlika fire last?
- According to the heat detections seen by satellite inside the perimeter, it burned from 5 April 2016 to 7 April 2016 (3 days). The perimeter dates it from 5 April 2016 to 6 April 2016.
- How much area did it burn?
- The perimeter Copernicus measured from satellite imagery is 2,836 hectares (28.4 km²). Official national figures may differ.
- Which municipalities burned?
- The fire entered 2 municipalities: Grad Vrlika (2,795 ha, 12 %); Općina Civljane (0 ha, 0.0 %).
- What was the weather like?
- During the fire the temperature reached 15.2 °C, humidity dropped to 42 % and gusts hit 30 km/h. The fire danger index (FWI) reached 4, 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 5 April 2016 to 6 April 2016. 59 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 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.
