Fire near Membach (BE)

50.53°N, 6.08°E · first detected on 14 August at 13:19

What the satellites measured

This fire was tracked from 14 August at 13:19 to 14 August at 22:10, through 35 satellite detections. The detected extent reaches 2,197 ha.

Detected extent: 2,197 ha
Cumulative power: 5,677 MW
Peak power: 713 MW
Detections: 35

“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.

Replay how the fire spread

The map is centred on this fire and loads only its detections. The timeline below covers the whole fire, from the first satellite pass to the last. “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.
