How sure is this?
The strongest area (#1) has 89% confidence. It appears in 6 of 6 later clear images, so it is not a one-day artefact. Radar confirmed some of these areas; the others rest on optical and seasonal evidence. Confidence measures how strong the evidence for real surface change is; it does not identify the cause or who did it.
How it was measured
SCOPE used Sentinel-2 optical imagery at 10 m, cloud-masked and combined over each period; Sentinel-1 radar, which sees through cloud, as an independent check; the same season in 2018, so normal seasonal change is not reported as real change. The whole analysis took 27 seconds.
