Almeida fire, June 2022 União das freguesias de Amoreira, Parada e Cabreira

Out · last detection 18 Jun 2022, 14:31 UTC

The fire started on 18 June 2022 in União das freguesias de Amoreira, Parada e Cabreira, Portugal, and satellites saw it burning for 1 day. Copernicus mapped a burnt perimeter of 103 hectares from satellite imagery, spread across a single municipality. According to ICNF, it was detected on 17 June 2022 at 16:20 and declared extinguished on 17 June 2022.

Number 103 in Portugal in 2022, of 107.

The power measured by the satellite is low (15.5 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

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 (CC0 1.0 Universal (CC0 1.0) Public Domain Dedication). 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.
