Fire near Couchey

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 detection and are not an official assessment: only the emergency services and the competent authorities are authoritative.

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.

Replay how the fire spread

The map is framed on this fire and loads only its detections. The timeline below covers the whole known life of the fire, from the first trace, satellite or report, to the last announcement from emergency services, and the ticks on the bar mark those announcements. Detections often stop before containment: a fire stops radiating once it stops spreading, which is exactly when it is declared contained. “1 h” shows what is burning within an hour of the chosen moment : the map then follows the power curve below and empties when it falls. “12 h” stacks twelve hours , as the home map does, where stacking avoids an empty screen between two satellite passes. Both are true, but they say different things.

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.

Separate fires, apart in time or in space, not pieces of this one. A single municipality can have several over one summer, and a forest massif often covers more than a hundred square kilometres.
