Gearchiveerd na 7 dagen zonder detecties. No satellite detection does not mean an area is safe. Cloud, sensor timing and heat below a sensor’s threshold can hide activity.
Satellite
Where the measurements are
Heat marks show satellite measurements. Orbit tracks are modelled; glow sizes and place-label positions are display context.
What each mark means
Footprint at this scaleVIIRS (NASA) 375 mMeteosat (EUMETSAT) about 1–3 km per cell · not drawn
- VIIRS (NASA)375 m
Measured positions. Drawn at true footprint scale, brightest layer.
- Meteosat (EUMETSAT)about 1–3 km per cell
Measures radiated power, which is what sizes the glow. Its individual pixel positions are not stored, so no Meteosat footprint is drawn — inferring one from the sharper layer would put a detection pixel on ground nobody measured.
- True geographic scale, corrected for latitude. Frame is about 48 km across.
- The glow means “an event, roughly here”. Its area follows the measured power and its radius is capped, because an uncapped one would assert a burnt extent nobody measured. The number carries the magnitude.
- Grey marks detections shown as history, including those on quiet or archived events. It does not establish that a later satellite pass measured no activity.
- Coastline, lakes and borders come from a generalised map with about 1,7 km between vertices, so treat every line as the shape of the geography and not as a surveyed boundary. It is drawn under the data and never over it.
- Place names sit at their own coordinates from an offline index of populated places. They say what is near the measurements — not that any named place is burning, and not how far the heat reaches.
- This event is quiet or archived, so its detections are drawn in history grey — . This status does not rule out recent heat detections or mean the activity is over.

Verification ladder
- ConfirmedNot yet observed
Two independent satellite looks recorded the same heat; one power reading or one VIIRS detection alone does not establish this step. Bevestigende sensoren: onbekend in het openbare record.
- QuantifiedObserved
The heat here has a number on it — radiated power, in megawatts — and the number is what lets one reading be compared with another from the same time of day, day by day. Between measurements it says nothing. Measured by: Meteosat (EUMETSAT), VIIRS (NASA).

What each sensor measured
Meteosat looks every ten minutes; VIIRS passes a few times a day. The contrast is the point — between sharp passes there is no new sharp knowledge, only the ten-minute layer.

Day and night observations stay labelled. REYKR does not compare unlike times of day.
Measurement record
Measured from 8 okt 2026, 09:40 to the most recent observation on 8 okt 2026, 14:14. Satellite readings in the 72 hours shown: 22, from VIIRS (NASA) and Meteosat (EUMETSAT). Highest power measured across the whole record: 78,4 MW, Meteosat (EUMETSAT) — 8 okt 2026, 12:10, .
This is a record of what satellites have measured so far, not a statement that the activity has ended. Only an official source can say that, and heat can return to ground that has gone quiet.

Questions about these readings
What has been observed near Amarante, Porto?
Gearchiveerd na 7 dagen zonder detecties. No satellite detection does not mean an area is safe. Cloud, sensor timing and heat below a sensor’s threshold can hide activity.
When was the last measurement near Amarante, Porto?
8 okt 2026, 14:14 UTC
How current is the last measurement near Amarante, Porto?
No signals: safe?
No. No detection is not proof of safety: cloud, missed passes, sub-threshold heat or failed reads leave activity unknown.
Missing or misplaced?
Buiten dekking of zonder bruikbare waarnemingen: onbekend. Meteosat-drempel ongeveer 12 MW; VIIRS 375 m; Meteosat ongeveer 1–3 km. Benaderde gebieden, geen brandgrenzen.
Data age?
Meteosat: every 10 min; median publication lag about 17 min, no deadline. VIIRS: usually 1–3 h after a pass. ANEPC: at least 600 s (10 min) between polls; no publication guarantee. Age per reading.
Sources?
Official above satellite. ANEPC: Portugal only. Meteosat (EUMETSAT); VIIRS (NASA): NOAA-20, NOAA-21; Suomi-NPP until its retirement in November 2026.
