The latest clear Sentinel-2 pass before this event and the earliest one after it.
20 Oct 2026, 13 days before this event. 4.7% 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.
