ArlB fire, March 2022 ArlB, J
The fire started on 22 March 2022 in ArlB, Hungary, and satellites saw it burning for 3 days. Copernicus mapped a burnt perimeter of 220 hectares from satellite imagery, spread across 2 municipalities.
It is the 8th largest in Borsod-Abaúj-Zemplén since 2016 (of 15 with a page). Number 11 in Hungary in 2022, of 22.
The power measured by the satellite is low (11.1 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

How it evolved, day by day
Fire radiative power detected each day, in megawatts, and number of hotspots. The magenta bar marks the peak day.
The weather it burned in
It had gone 5 days without rain (1 mm or more) when it started. Rain came after the fire: 1.0 mm on 30 Mar.
This area had burned before
No earlier perimeters overlap this fire since 2016, when the satellite record begins.

Frequently asked questions
- How long did the ArlB fire last?
- Copernicus dates it between 22 March 2022 and 24 March 2022: 3 days between the first and last image with fire.
- How much area did it burn?
- The perimeter Copernicus measured from satellite imagery is 220 hectares (2.2 km²). Official national figures may differ.
- Which municipalities burned?
- The fire entered 2 municipalities: ArlB (135 ha, 2.9 %); J (84 ha, 7.5 %).
- What was the weather like?
- During the fire the temperature reached 21.7 °C, humidity dropped to 10 % and gusts hit 26 km/h. The fire danger index (FWI) reached 15, class Moderate.
- Where does this data come from?
- From the EFFIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Hungary (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.

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 ADM3 (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.
