Persistent heat source near Itaguaí, Brazil
Right now
The most recent data we hold from NASA FIRMS (VIIRS) arrived 6 minutes ago, and this point is not in it. We record detections, not passes: an absence is not proof that nothing is there.
3 other detections within 20 km in the last 24 hours, the nearest <1 km from here.
The satellite has seen heat at this spot on 36 earlier days since 8 March 2026, in 7 of the twelve months of the year. Heat that is there in every season usually comes from industry (a steelworks, a refinery flare, a gas field) or from routine burning, not from a wildfire. NASA's data do not say which.
3 satellite detections of this fire · 31 October – 3 November 2026
A satellite sees a burning fire on each of its passes. This page gathers every detection of this fire; the address of each one leads here.
| Day and time (UTC) | Radiative power | Distance from Itaguaí |
|---|---|---|
| 3 Nov 17:30 | 142 MW | 8 km |
| 3 Nov 16:47 | 121 MW | 8 km |
| 31 Oct 16:45 | 72 MW | 8 km |
This page covers the record dated 31 October 2026. Browse recent observations in this area:
Recorded by satellite 3 days ago.
A thermal anomaly is a snapshot of one satellite pass, not a record of a fire’s life: we cannot say whether it kept burning after that pass.
It is the 5th strongest of the 26 detections recorded within 20 km of this point since 8 March 2026. Another comparable one was recorded here earlier the same day. 6 more were recorded here in the fortnight before it.
What the source measured
NASA FIRMS (VIIRS) reported 20 fire pixels with a combined fire radiative power of 72 MW, at nominal confidence, 8 km from Itaguaí.
The 20 pixels cover about 2.8 km² — that is the footprint of the detection grid at 375 m resolution, not an estimate of how much land burned.
FIRMS does not report burned area, and neither do we.
Urban PEI: 192,949 within a heuristic 35 km radius; not unique people.

How we know
One source: NASA FIRMS (VIIRS). Not yet confirmed by a second, independent source.
Our own score for this event is 39 out of 100.
This is our versioned heuristic index, not source severity or a calibrated probability. Urban PEI does not count unique people.
Computed under scoring rules v5. Rows carrying other versions were judged by different rules and are not directly comparable.
Series begins 8 March 2026. Comparisons refer to that period only. Collection gap: 14-26 August 2026.
This data is aggregated algorithmically from scientific sources. Not a replacement for official emergency warnings.

Safety information
Heat shows up at this spot regularly, which usually means an industrial plant or routine burning rather than a wildfire. Nothing on this page is an alert. In a real emergency, follow local authorities.
