The fire started on 17 August 2022 in Landal, Portugal, and satellites saw it burning for 4 days. Copernicus mapped a burnt perimeter of 618 hectares from satellite imagery, spread across 6 freguesias. According to ICNF, it was detected on 17 August 2022 at 13:45 and declared extinguished on 18 August 2022.
Number 21 in Portugal in 2022, of 107.
Perimeter published by EFFIS (Copernicus).
ICNF: 614 ha (matched records: 1). Difference between the page and the official record: +0.6%. Matched on 8 November 2026.
17 Aug 2022 to 20 Aug 2022: first and last day with fire on the page.
ICNF declared the fire extinguished on 18 August 2022. Satellites may still see smouldering spots afterwards.
Alert according to ICNF: 17 August 2022 at 13:45. Official cause: arson.
First day with fire on the page (satellite or perimeter): 17 August 2022.
VIIRS detections at 375 m. Most intense hotspot: 97 MW.
There is no official record to compare with. Each hotspot is a pixel detected in one satellite pass, not a separate fire.
Total radiative power on 17 August 2022; hotspots that day: 3.
Fire radiative power (FRP) measures the energy the fire gives off when the satellite passes. Added up by day, it compares intensity, not area.
Fire Weather Index (Canadian system) computed by WorldFires for the day the fire started. Consecutive days without rain before: 44.
This is an index computed from weather model data, not a measurement of the fire nor an official warning. Danger warnings are issued by each country’s authority. Emergency number and official warnings
High of 35.2 °C and minimum humidity of 13% on 19 August 2022; gusts of 61 km/h on 17 August 2022.
These are model values for a cell of about 25 km, not from a weather station: they may differ from what was measured on the ground.
This page’s change log has been kept since 24 October 2026: every night what it publishes is compared and the difference is logged. Anything earlier is reconstructed from each source’s date and marked as reconstructed.
Every night a snapshot of what the page shows is saved. If anything changes, it appears in the list as a log entry.
A version keeps the area, dates, name and official record; the area as it was logged (changes under 2% are not logged). The map, hotspots and weather always show today’s data.

Fire radiative power detected each day, in megawatts, and number of hotspots. The magenta bar marks the peak day.
It had gone 44 days without rain (1 mm or more) when it started.
No earlier perimeters overlap this fire since 2016, when the satellite record begins.

This compares size, not location: both shapes are at the same scale, north up, centred on each other.
Burnt area inside each freguesia, from crossing the official 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.
Land cover inside the perimeter according to Corine Land Cover, as reported by Copernicus.
Inside the perimeter there were about 0.48 hectares of 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.

It started with an FWI of 49.3, a minimum humidity of 50% and 44 days without rain. Fires in the area that started in weather like this since 2016: 9.
First rain (1 mm or more) after it ended: 8.3 mm on 28 Aug.
First rain (1 mm or more) after it ended: none in the following ten days.
First rain (1 mm or more) after it ended: none in the following ten days.
First rain (1 mm or more) after it ended: 1.7 mm on 24 Aug.
First rain (1 mm or more) after it ended: 1.8 mm on 25 Jun.
Fires in the area that started in similar weather: 9. With fewer than 15 we give no figures: they would be more noise than signal.
This is a bank of analogues: it shows what usually happens, not what will happen. With fewer than 15 twins we give no figures. How we calculate it
It was considered over on 20 Aug, and not even 1 mm fell in the following ten days: it went out without rain.

Drag the line to compare the same ground before the fire and after it.
If the day is cloudy, change the date: each satellite passes once a day. In false colour the burnt ground looks brown or red.
On 19 August 2022 the air beside the fire reached 15 µg/m³ of PM2.5, but no daily average passed the WHO guideline (15).

RSS Changes to this page With cross-checks and a citable version
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.
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. Freguesia boundaries come from geoBoundaries ADM3 (CC0 1.0 Universal (CC0 1.0) Public Domain Dedication). The area per freguesia is computed by WorldFires by crossing the perimeter with those boundaries, so it may differ slightly from each country’s official figure.
