Persistent heat source near Hamilton

CanadaNASA FIRMS (VIIRS)

Right now

The most recent data we hold from NASA FIRMS (VIIRS) arrived 9 hours ago, and this point is not in it. We record detections, not passes: an absence is not proof that nothing is there.

One other detection within 20 km in the last 24 hours, 1 km from here.

The satellite has seen heat at this spot on 444 earlier days since 10 February 2024, in 12 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.

33 satellite detections of this fire · 18 – 27 October 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.

Tick none to hear about every hazard.

One message per event, not per detection. We send a confirmation first, and every message carries a link to stop them. We store the address and the place, nothing else.

Recorded by satellite 10 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 15th strongest of the 92 detections recorded within 20 km of this point since 10 February 2024. Another comparable one was recorded here earlier the same day. 18 more were recorded here in the fortnight before it.

What the source measured

NASA FIRMS (VIIRS) reported 44 fire pixels with a combined fire radiative power of 109 MW, at nominal confidence, 4 km from Hamilton.

The 44 pixels cover about 6.2 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: 843,094 within a heuristic 35 km radius; not unique people.

Nearby, since 10 February 2024

How we know

One source: NASA FIRMS (VIIRS). Not yet confirmed by a second, independent source.

Our own score for this event is 53 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 for live collection; the monthly chart also counts backfilled detections from 10 February 2024. 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.
