Fire near 45.49°N, 4.25°E

What the satellites measured

This fire is not in the last thirty days of the fire list, but detections remain around this point: the curve below is rebuilt from the raw pixels, which are kept for a hundred days.

“Detected extent” is not “burned area”: it is the union of the ground footprints of the satellite pixels, and a 375 m pixel counts in full even when only a forest edge is burning. Compared with press figures it is in practice one and a half to three times the area reported. Detections taken at the edge of the scan swath, too coarse to measure anything at all, are excluded. These figures come from thermal satellite detection and are not an official assessment: only the local fire and civil protection authorities are authoritative.

1. Presumed over25 August at 10:00

   No further news — a day of silence for an active fire, four for a contained one — and no recent satellite detection nearby: the register closed the entry on its own. This is a presumption, not an announcement, and a new report would reopen it.

A "contained" fire is no longer spreading but is not out: crews remain on site and it can flare up again. Statuses and areas come from press reports and official sources, matched automatically; they are not an official record — only the prefecture and the fire service are authoritative. An entry with no news for ten days is closed automatically, and each entry's history keeps track of who announced what, and when.

The location

No satellite detected this fire: it is known only through press and official sources. There is therefore nothing to replay — the map shows the place, and the timeline above tells what was announced. This is the most common case in France: a fire of a few hectares brought under control in the afternoon slips between two overpasses without leaving a single hot pixel.

How the radiative power evolved

One point per satellite pass: the sum of the fire radiative power measured over the fire. This is the curve that says whether the fire eased off or picked up again, which no cumulative figure shows. The window covers 30 days; beyond that, clustering would merge two successive fires in the same place.
