Each image is a preview of a whole Sentinel-2 tile — an area of roughly 110 by 110 km, where one pixel is about 320 metres — not a close-up of the event, which may be a small part of it. "Clear" means under 30% cloud across the entire tile, so the exact place that matters can still be hidden. These are pictures for context, not an assessment of damage.
