The fire started on 15 January 2019 in Casamaccioli, France, and satellites saw it burning for 2 days. Copernicus mapped a burnt perimeter of 129 hectares from satellite imagery, spread across a single municipality.
It is the 23th largest in Haute-Corse since 2016 (of 27 with a page). Number 22 in France in 2019, of 26.
The power measured by the satellite is low (16.4 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.
Perimeter published by EFFIS (Copernicus).
BDIFF: 106 ha (matched records: 1). Difference between the page and the official record: +21.5%. Matched on 1 November 2026.
15 Jan 2019 to 16 Jan 2019: first and last day with fire on the page.
Satellites pass a few times a day and cloud or smoke can hide the fire: a lack of detections is not an official extinction. Each country’s emergency service declares a fire contained or out.
Alert according to BDIFF: 14 January 2019 at 20:15.
First day with fire on the page (satellite or perimeter): 15 January 2019.
VIIRS detections at 375 m. Most intense hotspot: 16 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 15 January 2019; hotspots that day: 19.
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: 26.
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 5.2 °C and minimum humidity of 25% on 15 January 2019; gusts of 41 km/h on 15 January 2019.
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 26 days without rain (1 mm or more) when it started. Rain came after the fire: 1.0 mm on 17 Jan.
No earlier perimeters overlap this fire since 2016, when the satellite record begins.
Burnt area inside each municipality, 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.
According to BDIFF, a fire of 106 ha was recorded in Casamaccioli on 14 January 2019 (the satellite measured 129 ha). The record has no coordinates, so it was matched by municipality and date.
BDIFF (Base de Données sur les Incendies de Forêts en France). This is the agency’s consolidated statistic: it measures the area in its own way, which is why it can differ from the satellite.
ECMWF ERA5 reanalysis at the fire location, the standard reference for past weather, and the Canadian Fire Weather Index (the same system Copernicus uses), computed by WorldFires from that data. Days after the fire run until the first rain.

It started with an FWI of 1.8, a minimum humidity of 25% and 26 days without rain. Fires in the area that started in weather like this since 2016: 7.
First rain (1 mm or more) after it ended: none in the following ten days.
First rain (1 mm or more) after it ended: 12.7 mm on 30 Mar.
First rain (1 mm or more) after it ended: 2.2 mm on 4 Mar.
First rain (1 mm or more) after it ended: 5.6 mm on 4 Mar.
First rain (1 mm or more) after it ended: none in the following ten days.
Fires in the area that started in similar weather: 7. 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 16 Jan, and on 17 Jan 1.0 mm fell. We do not know whether the rain or the firefighters put it out.

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 15 January 2019 the air beside the fire reached 16 µg/m³ of PM2.5, but no daily average passed the WHO guideline (15).

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. Municipal boundaries come from geoBoundaries ADM5 (Open Data Commons Attribution 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.
