Key figures

Course

Detections per period since the first observation. Each bar is a six-hour window; higher means more satellite pixels measured fire in that window. Most activity fell around 22-09 00:00 UTC.

Surroundings

Nearest town: Silva Escura (PT), about 2 km. Larger town nearby: Porto, about 15 km.

Observed by

This fire was seen by 8 satellite source(s): N21, S3B, S3A, SNPP, N20, MTG, MSG, MODIS. Polar satellites deliver sharp measurements but pass over a few times a day; geostationary satellites watch continuously with a coarser pixel.

How these figures are produced

FireSignal groups individual satellite detections into a single fire event. The heat zone is the sum of the measured pixels and is therefore an upper bound: it says where heat was observed, not how many hectares actually burned. Official figures from fire services or authorities are usually lower. Cloud and thick smoke block the view, so there is always a gap between two observations.
