The latest clear Sentinel-2 pass before this event and the earliest one after it.
23 Oct 2026, 7 days before this event. 2.1% cloud across the tile.
No clear pass yet. Sentinel-2 revisits every few days and cloud can hide a place for longer — this event is less than a day old, and a clear scene will appear here once one exists.
The white ring marks where the event was reported.
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.
Contains modified Copernicus Sentinel data 2026, found through the Earth Search catalogue (Element 84) and served from the AWS Open Data Sentinel-2 archive.
