Vardenis fire, 13 September 2022 Vardenis
The fire started on 13 September 2022 in Vardenis, Armenia, and satellites saw it burning for 1 day. Copernicus’s global GWIS system rebuilt a burnt perimeter of 400 hectares from heat detections, spread across a single municipality.
It is the 32th largest in Gegharkunik since 2016 (of 59 with a page). Number 15 in Armenia in 2022, of 21.

We have the GWIS perimeter for this fire, but the VIIRS sensors did not capture it in enough detail: no day-by-day evolution, but the split by municipality is there.

Where it burned
The weather it burned in
It had gone 5 days without rain (1 mm or more) when it started. Rain came after the fire: 1.1 mm on 22 Sept.
This area had burned before
10% of the perimeter overlaps earlier fires recorded since 2016: 43 ha in 2017. Part of it burned more than once, so the yearly figures add up to more than the 40 ha that had burned before.
What happened to each town

Vardenis where it started397 ha0.3 %
Burnt area inside each municipality, from crossing the GWIS perimeter with administrative boundaries. The distance runs from the point marking the centre of each area to the nearest fire: staying a kilometre away does not mean it reached the houses.
People and buildings inside the perimeter
GHSL 2020Inside the perimeter there was no noticeable built-up land and almost nobody lived there (GHSL 2020, satellite-based estimate).
This is an estimate on 100 m cells, made from satellite imagery and census data: it does not mean that homes burned or that anyone was harmed. The perimeter also contains land that never burned.

The smoke
CAMS · CopernicusOn 14 September 2022 the air beside the fire reached 17 µg/m³ of PM2.5, but no daily average passed the WHO guideline (15).

Frequently asked questions
- How long did the Vardenis fire last?
- GWIS (Copernicus) dates it between 13 September 2022 and 13 September 2022: 1 day between the first and last heat detection of the perimeter.
- How much area did it burn?
- The perimeter GWIS (Copernicus) rebuilt from heat detections is 400 hectares (4.0 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire only entered Vardenis (397 ha, 0.3 %).
- What was the weather like?
- During the fire the temperature reached 19.5 °C, humidity dropped to 21 % and gusts hit 38 km/h. The fire danger index (FWI) reached 14, class Moderate.
- Where does this data come from?
- From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Armenia (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: GWIS (Copernicus), rebuilt from heat detections rather than mapped on imagery.
- Dates from the perimeter: the VIIRS detections inside it did not change them. No 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.
- Built-up area and population come from the JRC Global Human Settlement Layer (epoch 2020, 100 m cells), summed inside the perimeter: an estimate of what was there, not a damage count.
Where this data comes from
The perimeter comes from the Copernicus Global Wildfire Information System (GWIS), which rebuilds it from MODIS and VIIRS heat detections and publishes it under CC BY 4.0. It is not measured on imagery as in Europe, so it is an estimate. 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 3.0 Intergovernmental Organisations (CC BY 3.0 IGO)). The area per municipality is computed by WorldFires by crossing the perimeter with those boundaries, so it may differ from each country’s official figure.
